Symposia: Interacting with the world: from neurons to social behavior
- Lorenzo Ferrucci
Presentation materials
Social interactions in primates are possible through the ability to extract relevant information from voices, for example their identity. The anterior Temporal Voice Area (aTVA) is a region in the anterior temporal lobe of humans, macaques and marmosets specialized in the processing of voices, but the exact voice information represented by individual neurons in the aTVA remains obscure.

Every day we interact with the world around us, and our ability to have successful social interaction depends on our ability to integrate different information coming from different social contexts. To this end, studies on animal models can provide valuable insights, offering a controlled environment to investigate neural mechanisms, explore behavioral dynamics, and understand the evolutionary...
Primates have a complex social life that requires monitoring and understanding the actions and choices of the other group members and learning from others' behavior. While previous behavioral studies have shown monkeys' remarkable observational learning abilities, how the information learned by observation is encoded at the neural level has not been studied yet. In this study, we recorded...
The evolution of frontopolar cortex (FPC) has been linked to advanced social skills typical to primates. Until recently, lesion and electrophysiological studies in macaques have revealed its role in exploratory behaviors and self-generated actions. Two of our previous electrophysiological works confirmed and broadened this role. FPC neurons encoded the different stages of a learning process...
Social interactions imply dynamic and synergic feedback loops in which actions, reactions, and internal states of each partner is modulated by the others. In this framework, interacting brains appear to operate as an integrated system, showing shared neural dynamics coevolving over time. In-phase brain oscillation alignment have been found in interacting people, but also in monkeys, bats, and...
