This page covers biological details of component Ventral Tegmental Area. Region is part of aHuman target integrated biological model.

• Top-down path to region: Midbrain Mesencephalon -> Ventral Tegmental Area (LMC.MM.VTA) (see Mind Maps)
• Type: nucleus
• Brain area: Lower Brain - Modulatory Contol Area
• Role: relay
• Function: Respond to novel stimuli, unexpected rewards, and reward predictive sensory cues
