Postmortem Cortical Brain Mapping in
Suicide and Depression
• Lower serotonin transporter binding in Major
Depression is widespread in PFC.
• Lower serotonin transporter binding in suicide is
highly localized to ventro-medial PFC.
• The ventro-medial prefrontal cortex is involved in
behavioral and cognitive restraint. Therefore,
deficient serotonin input to that brain region
could predispose to acting on suicidal or
aggressive feelings.
