This Month’s Highlights
A newly found brain circuit drives OCD-like behavior
Researchers identified a previously unknown connection between the amygdala (the brain’s threat detector) and the striatum (involved in habits). In mice, this circuit amplified repetitive behavior, and calming it prevented OCD-like symptoms. This is early animal research, but it points to more precise future treatments.

Four core brain hubs of OCD mapped
By studying people who developed OCD after a stroke or brain tumor, researchers pinpointed four core hubs in the orbitofrontal cortex and basal ganglia. The same areas light up in typical OCD, which could help aim brain-stimulation treatments (TMS) more precisely. (Biological Psychiatry, July 2026)
Closing the OCD treatment gap
An editorial in a leading journal highlights that OCD is common but often underdiagnosed, with too few trained specialists. It reviews brain-stimulation options, which reduce symptoms for many people, and calls for wider access to effective care. (Nature Mental Health, April 2026)
Brain regions linked to OCD during complex tasks
Brown University researchers found that people with OCD activated more brain regions than others while completing a sequencing task, including some areas not previously linked to OCD. These regions could become future treatment targets. (Imaging Neuroscience, February 2026)
