Research Statement

The response of cortical networks to stimulation is a complicated interaction between external drive and the ongoing pattern of internally generated activity. I study how experience changes the spatio-temporal properties of cortical activity in simulated recurrent networks and data from in vivo electrophysiology. I am particularly interested in the role of spontaneous activity in neural circuits, its relevance to prediction and memory and its connection to statistical learning.
