Neuroimaging study reveals how light-sensitive signals reach the brain and how regions associated with mood process those signals. Some regions of the cerebral cortex associated with cognitive and mood processing show sensitivity to light intensity.
The activation of a neural circuit comprising of the central nucleus of the amygdala and the bed nucleus of the stria terminalis in the first hours following sepsis infection induced anxiety behaviors in mice two weeks after the infection cleared.

Patients with mood and anxiety disorders have abnormally low activation in brain areas associated with cognitive and emotional control. Brain scans also revealed hyperactivity in brain areas linked to the processing of emotional thoughts.
People with mood and substance use disorders have reduced lifespan compared to their peers without a mental health disorder.

A new paper explores the phenomena of dissociation and calls for more understanding of the condition.
