Top-down feedback controls spatial summation and response amplitude in primate visual cortex
Feedback modulation of V1 is implicated in functions such as attention yet the precise neural mechanisms are not known. Here the authors report that optogenetic inactivation of V2 projections leads to modulation of V1 receptive field properties such as size, surround suppression and response amplitu...

| Sumario: | Feedback modulation of V1 is implicated in functions such as attention yet the precise neural mechanisms are not known. Here the authors report that optogenetic inactivation of V2 projections leads to modulation of V1 receptive field properties such as size, surround suppression and response amplitude. |
