The ventral tegmental area (VTA) (tegmentum is Latin for covering), also known as the ventral tegmental area of Tsai, or simply ventral tegmentum, is a group of neurons located close to the midline on the floor of the midbrain.
The ventral tegmental area, or VTA, is in the midbrain, situated adjacent to the substantia nigra. Although it contains several different types of neurons, it is primarily characterized by its dopaminergic neurons, which project from the VTA throughout the brain.
Sep 14, 2023 · Activation of the Ventral Tegmental Area (VTA): Upon the recognition of the rewarding stimulus, the VTA is stimulated to produce and release dopamine. The exact mechanism can vary: for natural rewards, the VTA responds to signals from other parts of the brain. For drugs of abuse, many directly increase dopamine production or release in the VTA. 3.
Mar 18, 2018 · Despite their importance in reward, motivation, and learning there is only sparse anatomical knowledge about the human medial forebrain bundle (MFB) and the connectivity of the ventral tegmental area (VTA).

May 1, 2019 · The ventral tegmental area (VTA) and substantia nigra pars compacta (SNc) are assumed to play a key role in dopamine-related functions such as reward-related behaviour, motivation, addiction and motor functioning.
May 20, 2022 · The ventral tegmental area (VTA) located in the midbrain controls diverse behavioral repertoire, including reward processing, aversion, stress modulation, drug addiction, learning, and memory ( Haber and Fudge, 1997; Ikemoto, 2007; Arias-Carrion et al., 2010; Polter and Kauer, 2014 ).
