Alcohol's effects on gene expression in the central nervous system

...gest that alcohol can produce changes in the brain reward system that can further increase the rewarding effects of alcohol." # Microarray techniques confirmed earlier reports indicating that chronic alcohol exposure/withdrawal differentially alters gene expression in the prefrontal cortex of mice.

The connections to the nucleus accumbens seem to be bidirectional, said the researchers, and the interactions with the pre...

Investigating 'brain shrinkage' in alcoholics

...ctive substances is that they provide an immediate reward in the intoxicating experience. When actively drinking, an individual's inhibition processes become impaired and can further contribute to poor decisions and excessive drinking. With prolonged bouts of drinking, dependence may ensue along with neural...

Cultural norms not unique to human societies

...cial bond with other group members than the simple reward of freeing the food." A characteristic traditionally thought to be solely human, the propensity to conform, may be part of an evolutionary progression. "These results suggest an ancient origin for the cultural conformism that is so evident in humans...

Gene controlling circadian rhythms linked to drug addiction

...ity, it may also be a key regulator of the brain's reward system. UT Southwestern researchers showed that, in mice, the Clock gene regulates the reward response to cocaine, suggesting that similar actions take place in humans. Findings from the multi-c...

Nose odors and mouth odors: The brain distinguishes

...d by retronasal stimulation creates a differential reward context for food but not for non-food odors by signaling availability versus receipt of food," they concluded. "Because the current study tested only one food, future experiments are needed to determine whether other food odors produce the same diffe...

Monkeys understand numbers across senses

...rchers chose to test each monkey only once and not reward them in any way. This experimental design meant that the monkeys could not learn anything within the experiment and instead were demonstrating their spontaneous numerical abilities. Other aspects of their experimental design avoided drawbacks in prev...

Researchers use brain scans to predict behavior

... world makes sense to you." Sapir noted that the reward systems' predictive abilities may be damaged or missing in some patients with mental illness, causing these patients to perceive the world as alien and unpredictable. Other areas involved in prediction included regions in the visual cortex involved...
