RT Journal Article SR Electronic T1 Categorical working memory codes in human visual cortex JF bioRxiv FD Cold Spring Harbor Laboratory SP 2021.12.16.472288 DO 10.1101/2021.12.16.472288 A1 Yan, Chang A1 Christophel, Thomas B. A1 Allefeld, Carsten A1 Haynes, John-Dylan YR 2021 UL http://biorxiv.org/content/early/2021/12/17/2021.12.16.472288.abstract AB Working memory contents are represented in neural activity patterns across multiple regions of the cortical hierarchy. It has remained unclear to which degree this reflects a specialization for different levels of abstraction. Here, we demonstrate that for color stimuli categorical codes are already present at the level of extrastriate visual cortex (V4 and VO1). Interestingly, this categorical coding was observed during working memory, but not during perception.Competing Interest StatementThe authors have declared no competing interest.
