The long-term goal of our research is to identify the neural circuits underlying perceptual and cognitive functions. To this end, we are studying the activity of single and populations of neurons recorded from animals trained to perform selected cognitive tasks. Cognitive functions emerge from computations implemented by neuronal networks and through application of a mixture of electrophysiological, behavioral, and computational techniques, we hope to play our role toward understanding the brain as a computational organ. Our current research focuses on the following topics: neuronal mechanisms involved in spatio-temporal dynamics of object representation, role of network states in preserving complex object information, neuronal feedback control for object recognition during partial occlusion, and the neuromodulatory basis of cognitive functions.
