Jongsma1 1Behavioural Science Institute, Radboud University Nijmegen, 2School of Psychology, Australian Catholic University, 3Department of Pediatric Rehabilitation, Sint Maartenskliniek Several children with unilateral Cerebral Palsy seem to disregard the preserved capacity of their affected upper limb.

To study underlying cognitive factors of upper limb control, an event-related potential protocol was developed.
