Abstract

A critical function of neural circuitry in the brain is detecting relevant features in the environment. The direction selective circuit in the retina is a classic model for studying neural mechanisms underlying feature detection. In this talk, I will discuss our recent work that focuses on the dendritic and synaptic mechanisms underlying retinal direction selectivity using a combination of synapse-specific genetic manipulations, two-photon calcium imaging, electrophysiology and pharmacology. Our results demonstrate that distinct sets of mechanisms are recruited to encode motion direction under different visual conditions. Therefore, direction selectivity in the retina is implemented by a dynamic and acutely modulated network that ensures robust feature detection in the complex natural environment.
