In addition, the nucleus accumbens, which plays a role in processing reward, has been shown to beinvolved in risky behaviorsin adolescents and adults. This region is rich in dopamine and suggests a further role for dopamine in risky behaviors. Tackling gambing addiction Currently, gambling disorder...
Researchers provide neurophysiological data suggesting that the lateral habenula provides input to dopamine neurons especially about the absence of rewards. Accordingly, latheral habenula receives inputs from the nucleus accumbens and the internal segment of the globus pallidus.Kimura...
Our difficulty, according to Daniel Nettle, is that the brain systems for liking and wanting are separate. Wanting involves two ancient regions the amygdala and the nucleus accumbens that communicate using the chemical dopamine to form the brain’s reward system. They are involved in anticipating ...
Referred to as the body’s control and communication network, the brain’s nervous system is responsible for receiving and processing all information in the body. It’s divided into two sections: the central nervous system (CNS) made up of the brain and spinal cord; and the peripheral nervous...
The majority of addictive substances induces increased levels of omovanillic acid (OVA), an index of dopaminergic activity, and heighten the release of dopamine in the nucleus accumbens, which is the terminal of the dopaminergic mesolimbic pathway [120]. On this basis, we can say that substance...

For years neuroscientists studying appetite focused mainly either on the hypothalamus, a brain area involved in regulating energy balance, or on reward-processing centers such asthe nucleus accumbens(伏隔核). But this group has identified a new feeding center in the brain, says Elanor Hinton, a ...
