A new study reveals impulsive behaviors may be triggered when dopamine passes from the amygdala to the BNST.
People exposed to two common agrochemicals, Paraquat and Maneb, are at a 250% higher risk of developing Parkinson's disease, researchers report.
When fruit flies experience an unexpected change in its surroundings, serotonin produced in the ventral nerve cord slows the insect down. The findings may shed light on the neurobiological mechanisms of human startle response.
Researchers improve motor function and reduce brain shrinkage in animal models of HD by adjusting the levels of a signaling protein.
Transplanted dopamine neurons from fetal tissues remained healthy in the brains of people with Parkinson's disease for 14 years.
The popularity of blind bag collectible toys is rapidly growing among children. Researchers report blind bags tap into the same psychological mechanisms that ultimately result in gambling addiction, namely intermittent reinforcement.
After 12 days of sugar intake, researchers noted major changes in both the dopamine and opioid systems of pigs' brains. Alterations in the opioid system were seen following the very first intake of sugar.
Using transcranial focused ultrasound in combination with injectable microbubbles, researchers open a pathway through the blood-brain barrier. The technique allows drugs to penetrate the brain and trigger therapeutic effects for those with neurodegenerative diseases.
Dietary triglycerides directly alter signaling in the reward circuit to regulate behavior. The findings reveal a potential mechanism by which triglyceride-rich diets may lead to adaptions in dopamine signaling that underlie reward deficit and compulsive behaviors.
