“Neural computations at the interface of vision and cognition”
We have a remarkable ability to recognize the behavioral significance of visual stimuli, and to plan task-appropriate behavioral responses. This talk will present parallel experimental and computational approaches aimed at understanding how visual feature encoding in upstream sensory cortical areas is transformed across the cortical hierarchy into more flexible cognitive encoding in the parietal and prefrontal cortices. The experimental studies utilize multi-electrode recording approached to monitor activity of neuronal population activity, as well as reversible cortical inactivation approaches, during performance of visually-based decision making tasks. Parallel computational modeling work employs machine learning approaches to train artificial neural networks to perform the same tasks as in the experimental work, allowing a deep investigation of putative neural circuit mechanisms used by networks to perform task-dependent cognitive computations.

“Coupling between the anterior cingulate cortex and the amygdala in primate social cognition”
How do we interact with others? Social interactions are characterized by a dynamic and contingent series of behaviors between at least two individuals. Experiments involving real-life interactions aimed at better simulating natural social behaviors may help elucidate the mechanisms underlying social cognition. In this talk, I will first discuss our recent finding on oscillatory coordination between the anterior cingulate cortex and amygdala that is associated with other-regarding (compared to self-regarding) preference toward a conspecific. Further, I will discuss how focal manipulations of the neuropeptide oxytocin influences this inter-regional coupling for other-regarding preference. Finally, I will discuss the neural basis of interactive gaze dynamics between pairs of macaques from the perspectives of local coding and inter-regional coordination.
