Sublinear integration underlies binocular processing in primary visual cortex

Longordo, Fabio; To, Minh-Son; Ikeda, Kaori; Stuart,Greg

Description

Although we know much about the capacity of neurons to integrate synaptic inputs in vitro, less is known about synaptic integration in vivo. Here we address this issue by investigating the integration of inputs from the two eyes in mouse primary visual cortex. We find that binocular inputs to layer 2/3 pyramidal neurons are integrated sublinearly in an amplitude-dependent manner. Sublinear integration was greatest when binocular responses were largest, as occurs at the preferred orientation and...[Show more]
