VTA and reward learning Ventral tegmental area (VTA). VTA efferents provide dopamine to the nucleus accumbens (ventral striatum) in the same way that the substantia nigra provides dopamine to the dorsal striatum because there is much evidence that it plays a central role in reward learning, the VTA-Na dopaminergic projection has attracted a great deal Of attention
