Joshua Trachtenberg

Joshua Trachenberg's lab is interested in the molecular and cellular processes of sensory processing and memory and on the connections between these two fundamental processes. They are also investigating how specific developmental disorders such as autism, alter these process. The focus is on the molecular and synaptic mechanisms of cortical plasticity, using the primary visual cortex as a model system. The lab is determining where experience-dependent plasticity is initiated in the cortical circuitry, how experience regulates the growth or retraction of synapses, and how plasticity mechanisms change with age.
