Preferred term

contralateral delay activity  

Definition(s)

  • A negative slow wave in the contralateral hemisphere where the items to be maintained are presented. CDA is an indicator of visual working memory capacity: its amplitude increases as the number of items to be maintained increases, but reaches an asymptote at 3-4 items.
