Nested deeper within the brain are essential structures such as the basal ganglia, the amygdala, and the hippocampus ... together form the body’s command structure: the central nervous system.

A large brain imaging study suggests that insomnia, depression, and anxiety—often co-occurring—share overlapping brain abnormalities.

The three main brain centers in the circuitry of anxiety—the amygdala, the hippocampus, and the prefrontal cortex (PFC)—are all subject to lasting shifts in structure and function as a result ...

Research explores overlapping and unique brain features in insomnia, depression and anxiety using brain scans. The findings reveal shared brain mechanisms, such as reduced cerebral cortex area.

Insomnia, depression, and anxiety are the most common mental disorders. Treatments are often only moderately effective, with ...

Volumes of the hippocampus and amygdala and subcortical grey matter including thalamus, caudate and putamen were calculated using the automated full brain segmentation process in Freesurfer ...
