where is the reward center of the brain located
Reward system The brain structures that compose the reward system are located primarily within the cortico-basal ganglia-thalamo-cortical loop;[11] the basal ganglia portion of the loop drives activity within the reward system.[11] Most of the pathways that connect structures within the reward system are glutamatergic interneurons, GABAergic medium spiny neurons, and dopaminergic projection neurons,[11][12] although other types of projection neurons contribute (e.g., orexinergic projection neurons). The reward system includes the ventral tegmental area, ventral striatum (i.e., the nucleus accumbens and olfactory tubercle), dorsal striatum (i.e., the caudate nucleus and putamen), substantia nigra (i.e., the pars compacta and pars reticulata), prefrontal cortex, anterior cingulate cortex, insular cortex, hippocampus, hypothalamus (particularly, the orexinergic nucleus in the lateral hypothalamus), thalamus (multiple nuclei), subthalamic nucleus, globus pallidus (both external and internal), ventral pallidum, parabrachial nucleus, amygdala, and the remainder of the extended amygdala.[6][11][13][14][15] The dorsal raphe nucleus and cerebellum appear to modulate some forms of reward-related cognition (i.e., associative learning, motivational salience, and positive emotions) and behaviors as well.[16][17][18] The laterodorsal tegmental nucleus, pedunculopontine nucleus, and lateral habenula(both directly and indirectly via the rostromedial tegmental nucleus) are also capable of inducing aversive salience and incentive salience through their projections to the VTA.[19][20][21][22]
Thalamus It is a midline symmetrical structure of two halves, within the vertebrate brain, situated between the cerebral cortex and the midbrain.
Cerebrum With the assistance of the cerebellum, the cerebrum controls all voluntary actions in the body.
