The ventral tegmental area (VTA) (tegmentum is Latin for covering), also known as the ventral tegmental area of Tsai, [1] or simply ventral tegmentum, is a group of neurons located close to the midline on the floor of the midbrain.
The Ventral tegmental area plays an important function in releasing the dopamine chemicals in our brain through the reward circuit. Any motivating behavior, pleasurable activity, chemical and non-chemical addiction and any behavior that contains a reward are known as dopamine-related functions.
The ventral tegmental area (VTA) is well known for regulating reward consumption, learning, memory, and addiction behaviors through mediating dopamine (DA) release in downstream regions. Other than DA neurons, the VTA is known to be heterogeneous and contains other types of neurons, including glutamate neurons.
The ventral tegmental area (VTA) is studied for its implication in a wide range of functions including the processing of salient sensory and emotional information, the control of motivated behavior, natural or drug-related reward, reward-related learning, mood, and their associated psychopathologies (Nestler and Carlezon, 2006; Fields et al ...
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.
Dopamine-releasing neurons of the ventral tegmental area (VTA) have central roles in reward-related and goal-directed behaviours. VTA dopamine-releasing neurons are heterogeneous in their...
Functions of the Ventral Tegmental Area. The role of the VTA in reward and motivation is perhaps its most well-known function. When we experience something pleasurable, whether it’s eating a delicious meal or receiving praise, the VTA becomes activated, releasing dopamine into the reward pathway. This surge of dopamine creates feelings of ...
Ventral tegmental area (VTA) dopamine neurons have important roles in adaptive and pathological brain functions related to reward and motivation.
The ventral tegmental area (VTA) is involved in adaptive reward and motivation processing and is composed of dopamine (DA) and GABA neurons.
The ventral tegmental area (VTA) in the brain’s reward circuitry is composed of a heterogeneous population of dopamine, GABA, and glutamate neurons that play important roles in mediating mood-related functions including depression.
