My laboratory seeks to understand the synaptic, network and metabolic changes in the brain that allow the developing visual system to begin to process information. Our immediate questions are (1) when are humans and other mammals first capable of sight, (2) what are the critical regulatory checkpoints leading to sight, and (3) why does this process occur when it does? We answer these questions by assaying the ensemble activity of the network using state of the art electrophysiological techniques, including multi-electrode arrays and intra-cellular recording, in behaving neonatal rodents. We believe a detailed understanding of early visual circuit development will provide a model for functional development throughout the brain, and clues to how this process becomes disrupted in neurological disorders.
