Donders Lecture - Dean Mobbs

Thursday 6 June 2024, 4 pm - 5 pm

In the Donders Lectures series on cognitive neuroscience, outstanding researchers in the field of brain and cognition present their work and ideas to a broad audience of scholars with a diversity of backgrounds, ranging from neuroscience to psychology and linguistics.

Dean Mobbs

In this talk, I discuss novel theoretical and empirical approaches to mapping the neural circuits, behaviors, and computations associated with ecologically-defined threat states. Naturalistic observations show that decisions to avoid or escape predators occur at different spatiotemporal scales and that they are supported by different computations and neural circuits. At their extremes, proximal threats are addressed by a limited repertoire of reflexive and myopic actions, reflecting reduced decision and state spaces and model-free (MF) architectures. Conversely, distal threats allow increased information processing supported by model-based (MB) operations, including affective prospection, replay, and planning.  I will discuss spatiotemporal approaches to examining the switch between each of these strategies and data inspired by economic models from the field of behavioral ecology examining the overt behaviors, computations, and neural circuitry associated with escape.
