Excessive anxiety can lead to psychiatric disorders, but it is an evolutionary trait that has helped us survive by alerting us to potential dangers. Researchers at Tohoku University have investigated how astrocytes within the habenula, a region of the brain associated with emotional processing, can tune anxiety levels.

While anger and aggression are instinctive behaviors found across many species, leaving these emotions unchecked can lead to conflict and violence. In a recent study, researchers at Tohoku University demonstrated that neuronal-glial interactions in the cerebellum determine the degree of aggression exhibited by mice. This suggests that future therapeutic methods could adjust glial activity in the cerebellum to help reduce unwanted aggression.
