- In animals, personality variations in response to stress and energy demands have been established. Cognitive processing of negative stimuli correlates with stress response patterns. Still, the relative contribution of cognitive appraisal or physiological demands to the behavioural output needs to be clarified. In this study we utilized reactive (high-responsive, HR) and proactive (low-responsive, LR) rainbow trout strains to investigate how contrasting reactions to hypoxia are related to individual variation in metabolism and/or cognition. The HR-LR strains did not differ in standard metabolic rate or hypoxia tolerance. HR trout displayed more pronounced avoidance to a signal cue after being conditioned with hypoxia, suggesting that they experienced this stimulus more aversive than LR trout. Together with differences in forebrain c-fos activation patterns in dorsomedial pallium, these results suggest cognitive differences between the strains. These results demonstrate that differences in personality/stress coping style can be related to contrasts in cognition, which are independent of metabolic differences.

Conference paper (peer-reviewed)abstract
- Searching for "The Internet of Things" may render thousands of hits in academic databases but a challenge still remains: to let students envision as well as work with the concept in a practical way. Designing "Things for the Internet" will not only require skills in engineering and electronics but also some understanding of digital service design and business models. This paper reports on work in progress between Belgium, Sweden and China. Students with different education backgrounds and levels hand over work (ideas) to others, to develop further. Currently, there are nine open-platform exercises to use as starting points for student work and discussions. Exercises are in English and free to download and use, as are some of the lectures related to them. So far, they are used in a digital service design class and in an introductory course in embedded systems. © 2017 IEEE.

Like a snowball : Adding layers of knowledge Enchanting student work with student input

Conference paper (peer-reviewed)abstract
- Internet of Things (IoT) seems to be a popular term nowadays, for business, society and teaching alike. Teaching students about such concepts and more importantly, making them aware of the many competency components (often called KSA-knowledge, skills, abilities) required in the development of IoT systems, services and products has been a major aim in the teaching design presented in this paper. The snowball metaphor symbolizes added layers of input, comments and suggestions delivered by Belgian, Swedish and Chinese students respectively, to peers with different backgrounds (study level, subject major, etc.). Open-platform exercises using Arduino kits are used as starting points and reports. Conceptualizations and suggestions are carried through the snowball ’chain’, which ends nearly two years later. Knowledge components are delivered e.g. through lectures. Among skills developed are practice in receiving input from and delivering output to groups different also in culture, knowledge, etc. Abilities include a demonstrated (and graded) proficiency in combining the acquired set of components, as demonstrated in workshops, discussions and reports, and in a proposed feedback loop to Sweden from China (not yet implemented). © 2017 IEEE.

How do individuals cope with stress? : Behavioural, physiological and neuronal differences between proactive and reactive coping styles in fish

Journal article (peer-reviewed)abstract
- Despite the use of fish models to study human mental disorders and dysfunctions, knowledge of regional telencephalic responses in non-mammalian vertebrates expressing alternative stress coping styles is poor. As perception of salient stimuli associated with stress coping in mammals is mainly under forebrain limbic control, we tested region-specific forebrain neural (i.e. mRNA abundance and monoamine neurochemistry) and endocrine responses under basal and acute stress conditions for previously characterised proactive and reactive Atlantic salmon. Reactive fish showed a higher degree of the neurogenesis marker proliferating cell nuclear antigen (pcna) and dopamine activity under basal conditions in the proposed hippocampus homologue (Dl) and higher post-stress plasma cortisol levels. Proactive fish displayed higher post-stress serotonergic signalling (i.e. higher serotonergic activity and expression of the 5-HT1A receptor) in the proposed amygdala homologue (Dm), increased expression of the neuroplasticity marker brain-derived neurotropic factor (bdnf) in both Dl and the lateral septum homologue (Vv), as well as increased expression of the corticotropin releasing factor 1 (crf(1)) receptor in the Dl, in line with active coping neuro-profiles reported in the mammalian literature. We present novel evidence of proposed functional equivalences in the fish forebrain with mammalian limbic structures.
