I found strong prefrontal projections to the lateral habenula in humans, with high fibre tract density around AM. It is possible that the PFC-LHb projections form collaterals in AM. AM is known for reciprocal connections with hippocampus, prefrontal cortex and retrosplenial cortex. What is its role?
