The '''Ventral tegmentum''' or '''Ventral tegmental area''' is part of the [[midbrain]] near the [[dorsal striatum]] and [[Substantia nigra]].
The Ventral tegmentum [[neurons]] primarily respond to the [[neurotransmitters]] [[dopamine]] and [[serotonin]]. It is thought to play a crucial rule in [[reinforcement learning]] particularly as computation of reward prediction and error in prediction. Researchers in [[neuroscience]] modeling have used [[Temporal difference learning]] to attempt to explain how animals might learn and the role of dopamine and the Ventral tegmentum area.
