- We have previously shown that deaf signers recruit partially different brain regions during simple arithmetic compared to a group of hearing non-signers, despite similar performance. Specifically, hearing individuals show more widespread activation in brain areas that have been related to the verbal system of numerical processing, i.e., the left angular and inferior frontal gyrus, whereas deaf individuals engaged brain areas that have been related to the quantity system of numerical processing, i.e., the right horizontal intraparietal sulcus. This indicates that compared to hearing non-signers, deaf signers can successfully make use of processes located in partially different brain areas during simple arithmetic. In this study, which is a conceptual replication and extension of the above-presented study, the main aim is to understand similarities and differences in neural correlates supporting arithmetic in deaf compared to hearing individuals. The primary objective is to investigate the role of the right horizontal intraparietal gyrus, the left inferior frontal gyrus, the hippocampus, and the left angular gyrus during simple and difficult arithmetic and how these regions are connected to each other. A second objective is to explore what other brain regions support arithmetic in deaf signers. Up to 34 adult deaf signers and the same amount of hearing non-signers will be enrolled in an functional magnetic resonance imaging study that will include simple and difficult subtraction and multiplication. Brain imaging data will be analyzed using whole-brain analysis, region of interest analysis and connectivity analysis. This is the first study to investigate neural underpinnings of arithmetic of different difficulties in deaf individuals.

- Deaf signers and hearing non-signers have previously been shown to recruit partially different brain regions during simple arithmetic. In light of the triple code model, the differences were interpreted as relating to stronger recruitment of the verbal system of numerical processing, that is, left angular and inferior frontal gyrus, in hearing non-signers, and of the quantity system of numerical processing, that is, right horizontal intraparietal sulcus, for deaf signers. The main aim of the present study was to better understand similarities and differences in the neural correlates supporting arithmetic in deaf compared to hearing individuals. Twenty-nine adult deaf signers and 29 hearing non-signers were enrolled in an functional magnetic resonance imaging study of simple and difficult subtraction and multiplication. Brain imaging data were analyzed using whole-brain analysis, region of interest analysis, and functional connectivity analysis. Although the groups were matched on age, gender, and nonverbal intelligence, the deaf group performed generally poorer than the hearing group in arithmetic. Nevertheless, we found generally similar networks to be involved for both groups, the only exception being the involvement of the left inferior frontal gyrus. This region was activated significantly stronger for the hearing compared to the deaf group but showed stronger functional connectivity with the left superior temporal gyrus in the deaf, compared to the hearing, group. These results lend no support to increased recruitment of the quantity system in deaf signers. Perhaps the reason for performance differences is to be found in other brain regions not included in the original triple code model.

Tidskriftsartikel (refereegranskat)abstract
- Congenital deafness is often compensated by early sign language use leading to typical language development with corresponding neural underpinnings. However, deaf individuals are frequently reported to have poorer numerical abilities than hearing individuals and it is not known whether the underlying neuronal networks differ between groups. In the present study, adult deaf signers and hearing nonsigners performed a digit and letter order tasks, during functional magnetic resonance imaging. We found the neuronal networks recruited in the two tasks to be generally similar across groups, with significant activation in the dorsal visual stream for the letter order task, suggesting letter identification and position encoding. For the digit order task, no significant activation was found for either of the two groups. Region of interest analyses on parietal numerical processing regions revealed different patterns of activation across groups. Importantly, deaf signers showed significant activation in the right horizontal portion of the intraparietal sulcus for the digit order task, suggesting engagement of magnitude manipulation during numerical order processing in this group.

- Interaction with the environment has a key role in refining the neuronal circuitry required for normal brain function throughout life. Profound effects of enriched environment have been shown on neuronal structure and chemistry in experimental animals. Epidemiological studies imply that this is true also in man, thus cognitive stimulation has a protective effect on neurodegeneration, e.g., in Alzheimer's disease. Glutamatergic pathways are imperative for cognitive functions, such as memory, learning and long-term potentiation, and relies on the AMPA and NMDA glutamate receptors and the hippocampus, with its specific subregions, is an important anatomical substrate in this. The glutamate signalling is also dependent on a fine-tuned transport system, in the hippocampus primarily achieved by the glutamate transporter EAAC1. In this study we show how environmental enrichment modulates these parts of the glutamatergic system using quantitative in situ hybridisation. This work demonstrates for the first time that environmental enrichment modulates the mRNA expression of EAAC1 which is significantly and region specifically decreased in the hippocampus. We also provide evidence for regional and hemisphere-specific upregulation of NMDA mRNA in the hippocampus after environmental enrichment. The current work also shows that AMPA mRNA of the hippocampus is not per se changed by environmental enrichment in adult animals. Taken together, our results extend the knowledge of the glutamatergic system of specific regions of the hippocampus and its modulation by environmental enrichment and could contribute to the development of strategies aimed at limiting pathological changes associated with glutamatergic dysfunctions. © 2007.

- Glutamate transporters regulate the glutamate concentration in the synaptic cleft within the CNS, a regulation required for normal brain function. In several neurological conditions, the amount of glutamate is altered. One reason for the changes in glutamate concentration might be impaired glutamate transporter function. In this study, an in situ hybridisation technique has been used to elucidate changes in mRNA expression of the glutamate transporter, excitatory amino acid carrier 1 (EAAC1), after treatment with the tricyclic antidepressant (TCA) amitriptyline. The results lead to the suggestion that treatment with tricyclic antidepressants leads to changes in the EAAC1 mRNA expression in rat brain suggesting involvement of the glutamate system in the tricyclic treatment of depression.

Multiplication engages phonological networks in Broca's area differently for deaf signers and hearing non-signers
- 2012
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- In hearing individuals, multiplication relies mainly on the phonological loop while subtraction relies on the visuo-spatial sketchpad (VSSP; Lee & Kang, 2002). Little is known about arithmetic neural networks in deaf signers (DS). Since DS often perform worse than hearing non-signers (NH) on arithmetic in general and multiplication in particular (Traxler, 2000), we hypothesized that there are strategic differences between how groups recruit the phonological loop in multiplication, but not in subtraction, leading to differential activation of phonological processing areas in left inferior frontal gyrus (Broca’s area). We investigated this using a blocked fMRI-design in which nine DS and 17 HN matched on age, gender, education and non-verbal intelligence (Raven & Raven, 1998) were tested on tasks of multiplication, subtraction and phonology (rhyme). The contrasts rhyme versus multiplication and rhyme versus subtraction were examined across groups within the region of interest defined by a probability map of Broca’s area (Amunts, 1999). We observed a significant interaction between task (multiplication and rhyme) and group (F = 12.64, p = .034, FWE-corrected), where the HN showed higher activation for rhyme than for multiplication (T = 4.55, p = .001, FWE-corrected) whereas there were no differences in activations between tasks for DS. For subtraction versus rhyme no interaction with group was found. These results suggest that there are differences between DS and HN in the phonology dependent neural networks in Broca’s area used during multiplication, which may be part of the explanation for poorer performance in DS.

Pharmacological and environmental modulations of the rat glutamatergic system

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Glutamate is the principal excitatory neurotransmitter in the central nervous system and it is implicated in neural transmission, learning, memory processes and neuronal plasticity. In the glutamatergic synapse two main components are present; the glutamate receptors and the glutamate transporters. The receptors, the NMDA, AMPA, kainite and the metabotroptic receptors, are responsible for conveying neural transmission, including long term potentiation (LTP), synaptic strengthening and modification. The transporters, located to the neuronal membrane and to the membranes of surrounding astrocytes, regulates the extracellular concentration of glutamate and thereby the duration of the synaptic signal.Alterations in both receptor and transporter systems have been suggested to be important in the pathogenesis of several acute and chronic nervous system diseases, such as psychosis, mood disorders, epilepsy, Parkinson's disease and Alzheimer's disease. The pathophysiology of these disorders is not yet completely understood and the involvement of glutamate is unclear. In this thesis we have sought to investigate the role of the glutamatergic system in the treatment of mood disorders and dementia. The antidepressant drug amitriptyline exerts its main effects on the serotonergic and noradrenergic systems and the antidementia drug rivastigmine acts mainly on the cholinergic system. However, given the close relationship between different neurotransmitter systems we have investigated the influence of amitriptyline and rivastigmine on the mRNA expression of the neuronal transporter, EAAC1, in rats. The results showed for the first time an involvement of EAAC1 in amitriptyline and rivastigmine treatment. Amitriptyline induced an acute increase in EAAC1 mRNA expression, which 24 hour after administration returned to baseline levels. Chronic treatment, on the other hand, induces a significant decrease in cortical areas, which we suggest results in enhanced neuronal transmission. Rivastigmine treatment, acute as well as chronic, induced increases in the mRNA expression in hippocampus. We hypothesize that this counteracts the excitotoxic glutamate levels seen in Alzheimer's disease.Further, environmental enrichment has been shown to have beneficial effects on capillary supply, the number of glial cells and dendritic spines, the thickness and weight of cortex, the concentration of cholinesterase, LTP and synaptic strength in animals. It has also been reported that humans that lead an active life have a reduced risk of developing Alzheimer's disease. This suggests that an active and stimulated life may have a protective effect against dementia in man, by creating a cognitive reserve which provides a buffer against brain pathology or age-related changes. We investigated the influence of environmental enrichment on the mRNA expression of NMDA and AMPA receptors and on EAACl and showed for the first time that EAAC1 mRNA is decreased after environmental enrichment. This is probably followed by an increase of glutamate in the synapse, which in turn leads to enhanced neuronal transmission including enhanced memory formation and learning. Furthermore, we confirmed in greater detail previous findings on the upregulation of NMDA mRNA and show that the regulation is regionally and hemisphere specific. We also confirm that AMPA mRNA is not per se changed by environmental enrichment in adult animals.This work provides further evidence about the involvement of the glutamatergic system in affective and cognitive disorders. Improved knowledge of the glutamatergic system will contribute to the development of strategies aimed at limiting pathological changes associated with glutamatergic dysfunctions.

Tidskriftsartikel (refereegranskat)abstract
- If the brain is deprived of input from one or more senses during development, functional and structural reorganization of the deprived regions takes place. However, little is known about how sensory deprivation affects large-scale brain networks. In the present study, we use data-driven independent component analysis (ICA) to characterize large-scale brain networks in 15 deaf early signers and 24 hearing non-signers based on resting-state functional MRI data. We found differences between the groups in independent components representing the left lateralized control network, the default network, the ventral somatomotor network, and the attention network. In addition, we showed stronger functional connectivity for deaf compared to hearing individuals from the middle and superior temporal cortices to the cingulate cortex, insular cortex, cuneus and precuneus, supramarginal gyrus, supplementary motor area, and cerebellum crus 1, and stronger connectivity for hearing non-signers to hippocampus, middle and superior frontal gyri, pre- and postcentral gyri, and cerebellum crus 8. These results show that deafness induces large-scale network reorganization, with the middle/superior temporal cortex as a central node of plasticity. Cross-modal reorganization may be associated with behavioral adaptations to the environment, including superior ability in some visual functions such as visual working memory and visual attention, in deaf signers.

- Alzheimer’s disease is a neurodegenerative disorder that affects the cholinergic, glutamatergic and monoaminergic systems in the neocortex and hippocampus. Today, the major pharmacological treatment involves the use of acetylcholinesterase inhibitors (AChEIs). In this study, an in situ hybridisation technique (using digoxigenin-labelled cRNA probes) was used to elucidate changes in mRNA expression of the neuronal glutamate transporter, rat excitatory amino carrier 1 (rEAAC1), after treatment with the AChEI rivastigmine. Compared with saline-treated rats, the rats subchronically (3 days) and chronically (21 days), but not acutely, treated with rivastigmine showed a significant increase in rEAAC1 mRNA expression in the hippocampal areas cornu anterior 1 (CA1), CA2, CA3 and dentate gyrus (p < 0.01), but not in the cortical areas. These results provide the first evidence that the glutamatergic system is modulated following acetylcholinesterase inhibition by rivastigmine, a finding, which is likely to be of importance for the clinical effects.

Similar digit-based working memory in deaf signers and hearing non-signers despite digit span differences

Tidskriftsartikel (refereegranskat)abstract
- Similar working memory (WM) for lexical items has been demonstrated for signers and non-signers while short-term memory (STM) is regularly poorer in deaf than hearing individuals. In the present study, we investigated digit-based WM and STM in Swedish and British deaf signers and hearing non-signers. To maintain good experimental control we used printed stimuli throughout and held response mode constant across groups. We showed that deaf signers have similar digit-based WM performance, despite shorter digit spans, compared to well-matched hearing non-signers. We found no difference between signers and non-signers on STM span for letters chosen to minimize phonological similarity or in the effects of recall direction. This set of findings indicates that similar WM for signers and non-signers can be generalized from lexical items to digits and suggests that poorer STM in deaf signers compared to hearing non-signers may be due to differences in phonological similarity across the language modalities of sign and speech.

- Deafness is generally associated with poor mental arithmetic, possibly due to neuronal differences in arithmetic processing across language modalities. Here, we investigated for the first time the neuronal networks supporting arithmetic processing in adult deaf signers. Deaf signing adults and hearing non-signing peers performed arithmetic and phonological tasks during fMRI scanning. At whole brain level, activation patterns were similar across groups. Region of interest analyses showed that although both groups activated phonological processing regions in the left inferior frontal gyrus to a similar extent during both phonological and multiplication tasks, deaf signers showed significantly more activation in the right horizontal portion of the inferior parietal sulcus. This region is associated with magnitude manipulation along the mental number line. This pattern of results suggests that deaf signers rely more on magnitude manipulation than hearing non-signers during multiplication, but that phonological involvement does not differ significantly between groups.Abbreviations: AAL: Automated Anatomy Labelling; fMRI: functional magnetic resonance imaging; HIPS: horizontal portion of the intraparietal sulcus; lAG: left angular gyrus; lIFG: left inferior frontal gyrus; rHIPS: right horizontal portion of the intraparietal sulcus

- Stimulus degradation adds to working memory load during speech processing. We investigated whether this applies to sign processing and, if so, whether the mechanism implicates secondary auditory cortex. We conducted an fMRI experiment where 16 deaf early signers (DES) and 22 hearing non-signers performed a sign-based n-back task with three load levels and stimuli presented at high and low resolution. We found decreased behavioral performance with increasing load and decreasing visual resolution, but the neurobiological mechanisms involved differed between the two manipulations and did so for both groups. Importantly, while the load manipulation was, as predicted, accompanied by activation in the frontoparietal working memory network, the resolution manipulation resulted in temporal and occipital activation. Furthermore, we found evidence of cross-modal reorganization in the secondary auditory cortex: DES had stronger activation and stronger connectivity between this and several other regions. We conclude that load and stimulus resolution have different neural underpinnings in the visual–verbal domain, which has consequences for current working memory models, and that for DES the secondary auditory cortex is involved in the binding of representations when task demands are low.

- Early deafness results in crossmodal reorganization of the superior temporal cortex (STC). Here, we investigated the effect of deafness on cognitive processing. Specifically, we studied the reorganization, due to deafness and sign language (SL) knowledge, of linguistic and nonlinguistic visual working memory (WM). We conducted an fMRI experiment in groups that differed in their hearing status and SL knowledge: deaf native signers, and hearing native signers, hearing nonsigners. Participants performed a 2-back WM task and a control task. Stimuli were signs from British Sign Language (BSL) or moving nonsense objects in the form of point-light displays. We found characteristic WM activations in fronto-parietal regions in all groups. However, deaf participants also recruited bilateral posterior STC during the WM task, independently of the linguistic content of the stimuli, and showed less activation in fronto-parietal regions. Resting-state connectivity analysis showed increased connectivity between frontal regions and STC in deaf compared to hearing individuals. WM for signs did not elicit differential activations, suggesting that SL WM does not rely on modality-specific linguistic processing. These findings suggest that WM networks are reorganized due to early deafness, and that the organization of cognitive networks is shaped by the nature of the sensory inputs available during development.

Acoustic Features Distinguishing Emotions in Swedish Speech.

Tidskriftsartikel (refereegranskat)abstract
- Few studies have examined which acoustic features of speech can be used to distinguish between different emotions, and how combinations of acoustic parameters contribute to identification of emotions. The aim of the present study was to investigate which acoustic parameters in Swedish speech are most important for differentiation between, and identification of, the emotions anger, fear, happiness, sadness, and surprise in Swedish sentences. One-way ANOVAs were used to compare acoustic parameters between the emotions and both simple and multiple logistic regression models were used to examine the contribution of different acoustic parameters to differentiation between emotions. Results showed differences between emotions for several acoustic parameters in Swedish speech: surprise was the most distinct emotion, with significant differences compared to the other emotions across a range of acoustic parameters, while anger and happiness did not differ from each other on any parameter. The logistic regression models showed that fear was the best-predicted emotion while happiness was most difficult to predict. Frequency- and spectral-balance-related parameters were best at predicting fear. Amplitude- and temporal-related parameters were most important for surprise, while a combination of frequency-, amplitude- and spectral balance-related parameters are important for sadness. Assuming that there are similarities between acoustic models and how listeners infer emotions in speech, results suggest that individuals with hearing loss, who lack abilities of frequency detection, may compared to normal hearing individuals have difficulties in identifying fear in Swedish speech. Since happiness and fear relied primarily on amplitude- and spectral-balance-related parameters, detection of them are probably facilitated more by hearing aid use.

Effects of mild-to-moderate sensorineuralhearing loss and signal amplification on vocalemotion recognition in middle-aged–olderindividuals

-
Tidskriftsartikel (refereegranskat)abstract
- Previous research has shown deficits in vocal emotion recognition in sub-populations of individuals with hearing loss, making this a high priority research topic. However, previousresearch has only examined vocal emotion recognition using verbal material, in which emotions are expressed through emotional prosody. There is evidence that older individualswith hearing loss suffer from deficits in general prosody recognition, not specific to emotionalprosody. No study has examined the recognition of non-verbal vocalization, which constitutes another important source for the vocal communication of emotions. It might be thecase that individuals with hearing loss have specific difficulties in recognizing emotionsexpressed through prosody in speech, but not non-verbal vocalizations. We aim to examinewhether vocal emotion recognition difficulties in middle- aged-to older individuals with sensorineural mild-moderate hearing loss are better explained by deficits in vocal emotion recognition specifically, or deficits in prosody recognition generally by including both sentencesand non-verbal expressions. Furthermore a, some of the studies which have concluded thatindividuals with mild-moderate hearing loss have deficits in vocal emotion recognition abilityhave also found that the use of hearing aids does not improve recognition accuracy in thisgroup. We aim to examine the effects of linear amplification and audibility on the recognitionof different emotions expressed both verbally and non-verbally. Besides examining accuracy for different emotions we will also look at patterns of confusion (which specific emotionsare mistaken for other specific emotion and at which rates) during both amplified and nonamplified listening, and we will analyze all material acoustically and relate the acoustic content to performance. Together these analyses will provide clues to effects of amplification onthe perception of different emotions. For these purposes, a total of 70 middle-aged-olderindividuals, half with mild-moderate hearing loss and half with normal hearing will perform acomputerized forced-choice vocal emotion recognition task with and without amplification

Evidence of an Effect of Gaming Experience on Visuospatial Attention in Deaf but Not in Hearing Individuals

Tidskriftsartikel (refereegranskat)abstract
- Auditory cortex in congenitally deaf early sign language users reorganizes to support cognitive processing in the visual domain. However, evidence suggests that the potential benefits of this reorganization are largely unrealized. At the same time, there is growing evidence that experience of playing computer and console games improves visual cognition, in particular visuospatial attentional processes. In the present study, we investigated in a group of deaf early signers whether those who reported recently playing computer or console games (deaf gamers) had better visuospatial attentional control than those who reported not playing such games (deaf non-gamers), and whether any such effect was related to cognitive processing in the visual domain. Using a classic test of attentional control, the Eriksen Flanker task, we found that deaf gamers performed on a par with hearing controls, while the performance of deaf non-gamers was poorer. Among hearing controls there was no effect of gaming. This suggests that deaf gamers may have better visuospatial attentional control than deaf non-gamers, probably because they are less susceptible to parafoveal distractions. Future work should examine the robustness of this potential gaming benefit and whether it is associated with neural plasticity in early deaf signers, as well as whether gaming intervention can improve visuospatial cognition in deaf people.

Konferensbidrag (refereegranskat)abstract
- Objectives Working memory (WM) capacity is similar for signed (SL) and spoken (SpL) language yet underlying temporal and spatial processing mechanisms may not be identical. To investigate this, two studies with deaf native signers (DS) and hearing non-signers (HN) were conducted. Methods DS and matched HN groups performed WM tasks with varying temporal and spatial demands in study 1 at encoding (temporal, spatial and mixed presentation styles) and in study 2 at retrieval (forward and backward span) and with abstract spatial demands (math span). Results DS performance was inferior with high temporal demands at encoding (temporal style) and retreival (forward span). There was no difference between groups with high spatial order demands at encoding (spatial style) or retrieval (backward span). DS performance was worse when abstract spatial processing was involved (math span). Conclusion WM processing mechanisms for SL and SpL differ for temporal information at encoding and retrieval and for abstract spatial information.
