Working Memory 2.0
Working memory is the fundamental function by which we break free from reflexive input-
output reactions to gain control over our own thoughts. It has two types of mechanisms …

Persistent spiking activity underlies working memory
Persistent activity generated in the PFC during the delay period of working memory tasks
represents information about stimuli held in memory and determines working memory …

Working memory: delay activity, yes! Persistent activity? Maybe not
Persistent spiking has been thought to underlie working memory (WM). However, virtually all
of the evidence for this comes from studies that averaged spiking across time and across …

Thalamic regulation of switching between cortical representations enables cognitive flexibility
Interactions between the prefrontal cortex (PFC) and mediodorsal thalamus are critical for
cognitive flexibility, yet the underlying computations are unknown. To investigate …

Shared neural mechanisms of visual perception and imagery
For decades, the extent to which visual imagery relies on the same neural mechanisms as
visual perception has been a topic of debate. Here, we review recent neuroimaging studies …
