In a mouse model of depression, Tak Pan Wong and colleagues at Douglas Hospital Research Centre tagged the engrams that formed after mice experienced social stress and examined their social avoidance behavior.

Activating the engram cells increased social avoidance behavior while suppressing the cells decreased it, suggesting a role in the cognitive symptoms of depression.
