The Aim

The Regehr Lab studies dynamic regulation of connections between neurons and the role of the cerebellum in behavior.

The Impact

Synapses are not fixed, static junctions. Their strength fluctuates from one moment to the next depending on recent activity. The lab is interested in the molecular machinery behind this flexibility, as well as the broader behavioral functions of the cerebellum.

Long associated with movement, the cerebellum is now understood to play an extensive role in social behavior and cognition. This research is revealing new connections between cerebellar dysfunction and conditions including autism, schizophrenia, and ataxia, and may open new avenues for treatment.

A Closer Look

Psychology Today — May 2020: Aggressive Behavior and the “Little Brain”

This Psychology Today feature covers the Regehr Lab’s use of light-activated proteins to control cerebellar neurons. Using this method, researchers found that they could rapidly dial mouse aggression up or down, challenging the long-held view that the cerebellum is purely a motor structure.

Harvard Medical School — October 2026: Delving Into the Cerebellum’s Complexity

This article describes research led by Wade Regehr showing that the cerebellar cortex is more complex than previously thought. Researchers identified many previously unknown cell types, including nine types of Purkinje cells rather than one. The article also discusses evidence that the cerebellar cortex plays roles in emotion and social behavior, and how this research may help inform understanding of conditions such as autism, anxiety, and ataxia. The accompanying graphic includes a blue-stained image of cerebellar tissue.
