Defining Outcome Measures for Behavioural and Emotional Problems in Dystrophinopathies

To evaluate the neurophysiological and physiological response to a classical conditioning task, which is comparable to findings that have been made in the mdx dystrophic mouse (deficient in Dp427). The investigators will assess correlations between the specific DMD/BMD genotype and susceptibility to conditioning, as well as the relationship between conditioning and behavioural/emotional characteristics of the syndrome.
