They identify two distinct population activity states – eyes open vs. closed – with notably stronger V4→V1 signaling in the foveal region during eyes-open periods. A cool example of how cognitive context reshapes visual cortical dynamics.</p><p>🌍 <a href="https://www.cell.com/cell-reports/fulltext/S2211-1247(24)00699-5" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">cell.com/cell-reports/fulltext</span><span class="invisible">/S2211-1247(24)00699-5</span></a></p><p><a href="https://sigmoid.social/tags/CompNeuro" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CompNeuro</span></a> <a href="https://sigmoid.social/tags/Neuroscience" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Neuroscience</span></a> <a href="https://sigmoid.social/tags/VisualCortex" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>VisualCortex</span></a> <a href="https://sigmoid.social/tags/NeuralManifolds" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>NeuralManifolds</span></a> <a href="https://sigmoid.social/tags/SystemsNeuroscience" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SystemsNeuroscience</span></a></p>

Visual working memories are abstractions of percepts – New #preprint by Duan and Curtis (2023)
Neurons in primary #VisualCortex (area V1) are driven by both sensory stimuli & nonsensory events; this study shows that during #visual & #auditory decisions, rat V1 represents multiple task features in an overlapping & distributed fashion #PLOSBiology https://plos.io/4840HPq

Thrilled to share our paper "Intrinsic timescales in the visual cortex change with selective attention and reflect spatial connectivity" now out at #NatureCommunications
https://www.nature.com/articles/s41467-023-37613-7
We have added interesting new analyses to our preprint version (thanks to the reviewers!),
so here goes a new summary:
