Social and emotional learning in the cerebellum

Van Overwalle, Frank

2024

Overview

The posterior cerebellum has a critical role in human social and emotional learning. Three systems and related neural networks support this cerebellar function: a biological action observation system as part of an extended sensorimotor integration network, a mentalizing system for understanding a person’s mental and emotional state subserved by a mentalizing network, and a limbic network supporting core emotional (dis)pleasure and arousal processes. In this Review, I describe how these systems and networks support social and emotional learning via functional reciprocal connections initiating and terminating in the posterior cerebellum and cerebral neocortex. It is hypothesized that a major function of the posterior cerebellum is to identify and encode temporal sequences of events, which might help to fine-tune and automatize social and emotional learning. I discuss research using neuroimaging and non-invasive stimulation that provides converging evidence for this hypothesized function of cerebellar sequencing, but also other potential functional accounts of the posterior cerebellum’s role in these social and emotional processes.The cerebellum’s canonical role in learning is expanding beyond movement coordination. In this Review, Van Overwalle details the systems and networks facilitating the cerebellum’s role in human social and emotional learning and discusses whether cerebellar temporal sequencing might account for this functionality.
