Revisiting the role of persistent neural activity during working memory

Highlights • Recent work suggests that the standard neural model of WM is in need of revision. • Multivariate analyses find that sensory cortex stores WM information. • lPFC simultaneously encodes multiple task variables to bias sensory regions. • WM is mediated by dynamic population codes in additi...

Description
Summary:Highlights • Recent work suggests that the standard neural model of WM is in need of revision. • Multivariate analyses find that sensory cortex stores WM information. • lPFC simultaneously encodes multiple task variables to bias sensory regions. • WM is mediated by dynamic population codes in addition to persistent neural activity.
