Our laboratory seeks to understand how the brain receives, computes, encodes and transmits information. More specifically, we’d like to learn which biophysical and morphological features equip synapses, neurons and networks to perform these tasks. The retina is a model system for the study of neuronal information processing: We can deliver precisely defined physiological stimuli and record with high fidelity the output of the retina, as well as activity at various points within the network; in addition, retinal circuitry is particularly well understood, enabling us to interpret more directly the impact of synaptic and cellular mechanisms on circuit function; finally, new genetic tools permit us to identify specific neuronal subtypes, record their activity and manipulate their influence on the network. I will present recent experiments in the lab that exploit these advantages to examine how synapses and neurons within the retinal circuit perform specific visual computations. I will focus on amacrine cells, interneurons in the inner retina that confer spatiotemporal complexity on the visual signals sent by ganglion cells to the rest of the brain.
