Our latest findings show that when we remember the duration of a visual event, we don’t use the same organisational format in working memory as when we retain other visual features such as colour. Check out our recent preprint, led by @annavanharmelen.bsky.social here: doi.org/10.64898/202...

In the IPS, but not the VC, spatial locations generalized across hemifield by sequence position. E.g., a location at the left point of the star in the left hemifield shared a common code with the left point of the star in the right hemifield. This indicates abstract coding of sequence in the IPS.

Online Now: Sensory reformatting for a working visual memory
dlvr.it
Sensory reformatting for a working visual memory
A core function of visual working memory (WM) is to sustain mental representations of recent visual inputs, thereby bridging moments of experience. This is thought to occur in part by recruiting early ‘sensory’ cortical regions, via flexible fronto-parietal mechanisms. The nature of visual cortex activity during WM has been elusive, but new evidence suggests that early WM representations can transform from a sensory-like code into a format that is shaped by task context and optimized for behavior. Here, we review evidence for transformations in visual cortical WM coding, the various forms they take, and their functional importance. Visual cortex may be an active workspace during WM, where flexible and ‘good enough’ WM representations serve to interface with perception and action.
