Converging evidence suggests that animals are motivated by curiosity, the intrinsic desire to know, but little is known about the mechanisms of this process. I will discuss historical reasons for why curiosity has been neglected in cognitive science, and the crucial importance of this process for higher cognitive functions and ecological behavior beyond the narrow confines of the laboratory. I...
Cooperation in primate species relies on advanced social cognition, but the behavioral and neural mechanisms supporting cooperative behaviors remain unclear. To investigate this, we examined freely moving marmoset dyads in a cooperative lever-pulling task. Marmosets successfully coordinated their actions, relying on social vision rather than environmental cues. Causal dependencies between...
We study the neural basis of natural behaviors, in particular navigation and social behaviors – taking a “Natural Neuroscience” approach. In my talk I will discuss three recent studies: (1) Our recent discovery that in social groups, hippocampal neurons encode rich social signals – including the identities, sex, hierarchy, and affiliation of other individuals. (2) A coding-transformation that...
The cerebral cortex exhibits strong recurrent connectivity governed by complex wiring rules. Recent advances allow probing this circuitry through optogenetic perturbations of single or few neurons, yet a general theory linking these responses to underlying connectivity is lacking. Here, we develop an exactly solvable framework to predict responses to perturbations in networks with multiple...
