🧵 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!

Seems like there is a new ultracompact #femtosecond #laser source for #multiphoton #microscopy in town! 50 MHz rep rate means a 2-3 m cavity if there is a single pulse circulating in the cavity - folding that into that compact of a form factor is quite impressive!

Catching up from the dead time w/o X, here is the excellent recently published study by Sara Jamali with @standehaene.bsky.social using the local-global prediction paradigm in mice. Oddball signaling is not just adaptation. Sequence chunking responses in VIPs. And some more doi.org/10.7554/eLif...
Parallel mechanisms signal a hierarchy of sequence structure violations in the auditory cortex
Responses to local and global violations in sound sequences are prediction errors and not simply the consequence of stimulus-specific adaptation.
