🧵 New paper out🚨🧠! Information about motion is key to vision. Head motion signals from the vestibular system robustly modulate visual cortex activity. Despite this profound modulation, we still don’t know how these signals reach visual cortex - or even what aspects of head motion are transmitted.
🤯 👁️ Did you know the primary visual cortex tracks head movements even in complete darkness?
Guy Bouvier and colleagues managed to decode multiple head movement variables in V1 without light in the room, and discovered two distinct brain sources delivering these signals!

New results! Visual adaptation changes the geometry of V1 population activity: frequent stimuli elicit smaller responses but become more discriminable. Similar results are seen in ANNs trained with metabolic constraints, suggesting these changes emerge from efficient coding. bit.ly/3VJHXRn
Adaptation shapes the representational geometry in mouse V1 to efficiently encode the environment
Sensory adaptation dynamically changes neural responses as a function of previous stimuli, profoundly impacting perception. The response changes induced by adaptation have been characterized in detail...

🚨Thrilled to share our latest work with @alesz.bsky.social, N. Brunel, and M. Scanziani! In this study, we explored how head movement are encoded in mouse primary visual cortex and identified the main source of this signal reaching V1: biorxiv.org/content/10.110…
Thread coming soon!
