Ventral Tegmental Area

@@Home -> BiologicalLifeResearch -> BrainAreaLMC -> BrainRegionLMC_MM_VTA

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) (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
