Researchers report they have discovered the region of the brain that registers excitement over a preferred food option. The study reports the findings could help develop new therapies and treatments to potentially combat obesity and encourage healthier eating.
A new study provides insight into the neurobiological underpinnings of envy. Researchers have identified a part of the brain that specifically registers when another receives a reward. This affects the subjective value placed on personal resources and rewards.
A neuroimaging study conducted by researchers from UCLA reveals the brains of people with schizophrenia are less sensitive to social rewards than they are to non-social rewards.
Researchers have identified two subpopulations of neurons in the BNST that connect to separate populations of neurons in the lateral hypothalamus which appear to drive two opposing emotional states; avoidance and reward seeking
Researchers identify a driving network for compulsivity in those with alcohol use disorders. The study reports heavy drinkers have more activity in the prefronal cortex, insular and striatum, areas of the brain critical for reward and decision making.
Researchers say melanocortin 4 receptors may play a role in unease and reward. The study reports dopamine levels fell in the reward system of mice when the animal experienced something unpleasant. However, in mice lacking the melanocortin 4 receptor, dopamine levels increased slightly following a negative experience.
Researchers report the brain's reward network could play an influential role in evaluating the opportunity to gain new information, just as it does to evaluate rewards such as food or financial gain.
Researchers say our neural circuits could be responsible for why we find comfort in those who are similar to us and why we are often uneasy with those who might differ from us.
Researchers reveal how molecular alterations in the brain are linked to behaviors central to addiction.
