Top-down feedback controls spatial summation and response amplitude in primate visual cortex

RT @kw_cooper: @LecoqJerome @prokraustinator @hb_cell @PessoaBrain Not sure about MT, but this paper did it in V2 / V1 https://t.co/T4QDWEg…

@neurograce The Rao and Ballard model (Figure 5) predicts reduced surround suppression with inactivated top-down feedback. This is what we found with optogenetic inactivation of the axon terminals of V2-to-V1 feedback in marmosets. https://t.co/hlFvoKVUaC
