Now out in #ScienceAdvances: @baiweiliu.bsky.social and I ask how internal (goal) and external (sensory) selection are coordinated during visual search. The key insight: internal and external selection are not inherently serial, but may develop in parallel in the human brain: doi.org/10.1126/scia...
Concurrent selection of internal goals and external sensations during visual search
Internal and external selection processes can codevelop in time to yield efficient search behavior.

Online Now: Sensory reformatting for a working visual memory
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.
