Learning in a sensory cortical microstimulation task is associated with elevated representational stability
R Pancholi, L Ryan, S Peron - Nature communications, 2023 - nature.com
Sensory cortical representations can be highly dynamic, raising the question of how
representational stability impacts learning. We train mice to discriminate the number of …

[HTML][HTML] Excitation creates a distributed pattern of cortical suppression due to varied recurrent input
Dense local, recurrent connections are a major feature of cortical circuits, yet how they affect
neurons' responses has been unclear, with some studies reporting weak recurrent effects …

[HTML][HTML] Sparse and distributed cortical populations mediate sensorimotor integration
R Pancholi, A Sun-Yan, M Laughton, S Peron - bioRxiv, 2023 - ncbi.nlm.nih.gov
Touch information is central to sensorimotor integration, yet little is known about how cortical
touch and movement representations interact. Touch-and movement-related activity is …

[HTML][HTML] Representational drift in barrel cortex is receptive field dependent
A Alisha, V Bettina, P Simon - bioRxiv, 2023 - ncbi.nlm.nih.gov
Cortical populations often exhibit changes in activity even when behavior is stable. How
behavioral stability is maintained in the face of such 'representational drift'remains unclear …

Brain-machine interface learning is facilitated by specific patterning of distributed cortical feedback
Neuroprosthetics offer great hope for motor-impaired patients. One obstacle is that fine
motor control requires near-instantaneous, rich somatosensory feedback. Such distributed …
