Roberto A. Gulli


I completed my PhD in Neuroscience at McGill University, where I studied the function of a brain area called the hippocampus in monkeys. To do this, I developed custom-made virtual reality tools and trained monkeys to complete multiple cognitive tasks in a stable virtual environment. In resulting publications, I've shown that hippocampal neurons encode diverse elements of experience related to ongoing behavior and memory of recent experience.

In a collaboration with Drs. Daniel Salzman & Stefano Fusi, I'm now studying how deliberative decisions are derived from neural representations of objects, memories, and context. My project combines the use of virtual reality, large-scale electrophysiology across a number of brain areas, and other behavioural recording techniques in rhesus monkeys.
