Broadly, my lab is interested in studying in mechanistic, molecular and computational terms fundamental features of central neuron’s function and plasticity. My presentation will provide an overview of two main research orientations currently being pursued in the lab. First, I will describe electrophysiological, behavioral and optogenetic experiments used within a computational framework that seek to identify the processing features of the dorsal raphe, a midbrain nucleus enriched with 5-HT neurons, and how they dynamically impact behavior. Second, I will present work that defines the nature of the so-called and still elusive ‘eligibility traces’ in cortex, a time decaying synaptic process that allows individual neurons to bind inputs that are separated in time. This mechanism provides an attractive cellular model of associative learning.
