- Ten healthy volunteers were subjected to a vestibulo-oculomotor test battery before, during and 1 hour after trichloroethylene exposure. The concentration of trichloroethylene in in-spiratory air was 32–78 ppm (176429 mg/m3). The concentration of trichloroethylene in venous blood was followed throughout the experiment. The mean pulmonary uptake was estimated. Each test person was also subjected to a control experiment, breathing air free of trichloroethylene. A decreased ability to visually suppress the vestibulo-oculomotor reflex during sinusoidal stimulation was noticed during trichloroethylene exposure. One hour after exposure the test subjects showed a decreased maximum velocity of the voluntary saccade and a decreased ability to follow a sinusoidally moving target.

- The short-term effect of exposure to toluene on the vestibulo- and opto-oculomotor system in rats was investigated. Stimulation of the vestibulo- and opto-oculomotor system was either a constant rotatory acceleration, a sinusoidal oscillation, a randomized oscillation or an optokinetic stimulation. Eye movements in response to the different stimulations were recorded by EOG and fed into a computer for analysis. Due to toluene exposure the slow phase velocity gain during constant acceleration increased and the post-acceleratory nystagmus response was prolonged. The optokinetic gain at stimulation velocities above 10 deg/sec decreased during toluene exposure. Toluene also prolonged the duration of optokinetic after-and after-afternystagmus. The findings in this study strongly suggest an effect of toluene on the cerebellum.

Cognitive development in children with cochlear implants: Relations to reading and communication
- 2008

Konferensbidrag (refereegranskat)abstract
- The purpose of the present article is to present an overview of a set of studies conducted in our own laboratory on cognitive and communicative development in children with cochlear implants (CI). The results demonstrate that children with CIs perform at significantly lower levels on the majority of the cognitive tasks. The exceptions to this trend are tasks with relatively lower demands on phonological processing. A fairly high proportion of the children can reach a level of reading comprehension that matches hearing children, despite the fact that they have relatively poor phonological skills. General working memory capacity is further correlated with the type of questions asked in a referential communication task. The results are discussed with respect to issues related to education and rehabilitation.

- This report summarizes some of the results of studies in our laboratory exploring the development of cognitive, reading and prosodic skills in children with cochlear implantation (CI). The children with CI performed at significantly lower levels than the hearing comparison group on the majority of cognitive tests, despite showing levels of nonverbal ability. The differences between children with CI and hearing children were most pronounced on tasks with relatively high phonological processing demands, but they were not limited to phonological processing. Impairment of receptive and productive prosody was also evident in children with CI. Despite these difficulties, 75% of the children with CI reached a level of reading skill comparable to that of hearing children. The results are discussed with respect to compensation strategies in reading.
