Generally a depressed person shows prefrontal hypofunction. Especially left prefrontal hypofunction. As well depressed people tend to have hyperactivity in the limbic system. Effective antidepressants oftentimes tame down the limbic system and turn on the prefrontal cortex.
This was one thing noted in sleep deprivation. After 24 of total sleep deprivation the limbic system showed less activity and prefrontal had more. Antidepressants also tend to lower dopamine in the limbic system when effective.Linkadge
