WebAboutTranscript. The reward pathway of the brain is connected to areas of the brain that control behavior and memory. It begins in the ventral tegmental area, where neurons release dopamine to make you feel pleasure. The brain begins to make connections between the activity and the pleasure, ensuring that we will repeat the behavior.
WebThe subthalamic nucleus is part of the diencephalon; as its name implies, it is located just below the thalamus. The substantia nigra is a midbrain structure, composed of two distinct parts: the pars compacta and the pars reticulata. The substantia nigra is located between the red nucleus and the crus cerebri (cerebral peduncle) on the ventral part of the midbrain.
WebWith the loss of dopamine neurons in Parkinson’s disease, however, there is an increased amount of activity in the indirect pathway. As a result, the thalamus is kept inhibited.
