Title of the talk:
Neural circuits and the cognitive map of space: insights from single neurons
Andrea Burgalossi studied Biology at the University of Perugia (Italy). In 2003 he joined the International Molecular Biology PhD Program in Göttingen. During his PhD in the laboratory of Prof. Nils Brose he investigated the molecular mechanisms of synaptic vesicle exocytosis. Shortly after graduation, he jumped from “cell culture & molecules” to “whole-brain & behavior”: he joined the laboratory of Prof. Michael Brecht (Berlin), where he contributed to the development of innovative methodologies for studying how single neurons, recorded in freely-moving animals, contribute to cognition and behavior. Since 2013 he is Junior Group Leader at the Werner-Reichardt Centre for Integrative Neuroscience (Tübingen). His team is currently exploring the cellular mechanisms of spatial representations in the mammalian brain.

The experimental accessibility of internally-generated patterns of activity (i.e. place cells and grid cells) offers an unprecedent opportunity for exploring the mechanisms of a “cognitive map of space” at the cellular, circuit and synaptic level. Experiments in the Burgalossi lab are centered on newly-established techniques for performing juxtacellular recordings from single neurons in freely moving rodents. These methods allow to visualize neuronal circuits in animals engaged in unrestrained, natural behaviours. In combination with anatomical and molecular tools, his research aims at dissecting the structural determinants of cognitive spatial behaviours.
