Talk by Nachum Ulanovsky (Weizmann Institute of Science, ISR): Neural codes for natural behaviors in flying bats
“Natural Neuroscience” aims to decipher the neural mechanisms of natural behaviors in freely-moving animals. This talk will focus on studies of neural codes for space, time, and social behaviors - in flying bats - using wireless neurophysiology methods that we developed. It will highlight new neuronal representations discovered in animals navigating through 3D spaces, or very large-scale environments, or engaged in social interactions. In particular, I will discuss 3D grid cells in flying bats - which turned out to refute predictions of several theoretical models; I will describe the hippocampal representation of an ultra-large 200-meter environment - which revealed a surprising multi-scale code for space that is fundamentally different from spatial codes reported for small environments; and I will also talk about the spatial representation of other individuals, in a social setting. The lecture will propose that neuroscience experiments - in bats, rodents or humans - should be conducted under evermore naturalistic conditions.
