Research on the brain basis of behavior. Covers reward and pleasure signals, attention in children, taste circuitry, and adaptive AI models.
Researchers found that PKA signaling regulates both alcohol-seeking behavior and sensitivity to alcohol intoxication in mice. Mice with a mutation in the RIIb subunit of PKA drank nearly twice as much 20-percent alcohol solution, while recovering faster from sedative effects.
A new study at Ohio State University suggests that Vietnamese Amerasians' thoughts and feelings about their American biological fathers play a powerful role in how well they adjust to life in the United States. The study found that those who reported frequent thoughts of their biological father experienced higher levels of psychologica...
Researchers discovered that sea slugs, despite their simple brain structure, make decisions based on a sliding scale of pleasure and pain. Hungry snails are quicker to strike at tempting food sources, while satiated ones avoid danger, reflecting the need for a meal to overcome prey defenses.
Researchers found that fruit flies exhibit behavioral and molecular changes similar to those observed in mammals, suggesting they may be capable of sleeping. The study provides new insights into the functions of sleep and could lead to the development of new treatments for human sleep disorders.
Researchers studied a c. elegans worm with a genetic mutation affecting its feeding behavior and discovered that it altered the potassium channel EXP-2, leading to muscle relaxation and reduced food intake. This study provides new insights into the molecular mechanisms controlling behavior in humans.
Aging hamsters who received a new biological clock had their lifespan increased by 20%, proving the importance of circadian rhythms to health and longevity. Behavioural modifications, such as structured light-dark cycles, may achieve similar benefits in humans.
