Cortical abnormalities Cortical brain areas implicated in depression are the dorsal and medial prefrontal cortex , the dorsal and ventral anterior cingulate cortex , the orbital frontal cortex and the insula. There have been studies showing a change in brain activity when mood shifts, but there is now also research showing a change in brain shape that appears to be associated with severe mood disorders. The brain shrinks , or rather, certain parts of it do.

One of those parts is called the hippocampus. This part is associated with making and being able to recall memories. When it comes to depression, the brain’s hippocampus , prefrontal cortex and amygdala are involved.

Besides ECT, other technologies have been developed in recent years. They treat depression by stimulating areas of the brain that are believed to control mood.
