Neuroimaging reveals how dopamine released from the striatum influences brain activity in the motor cortex and insular. Read More
Lamprey brain study provides new insights into how the human brain evolved. Read More
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. Read More
Researchers report the hormone prolactin, more commonly associated with lactation in new mothers, may underlie why women are more vulnerable to developing functional pain syndromes than men. Read More
Exposure to perfluorooctane sulfonate and perfluorooctanoic acid, so-called "forever chemicals," results in a decline of both dopamine levels and dopamine neurons in roundworms. Read More
Dopamine may play a role in activating immune cells to migrate in the early stages of infection. Read More
Researchers investigate the role the dopamine 2 receptor plays in psychosis. Read More
Everyone knows consuming junk food is bad for your health, but a new study reveals it could also be bad for developing brain health. Excessive consumption of calorie-dense foods can lead to changes in the structure and function of the prefrontal cortex, including altering dopamine signaling and inhibition. Read More
Researchers have identified a novel neurotransmitter system in the brain. The system signals transmission of innate olfactory information to areas of the brain associated with emotional processing via the TAAR5 receptor. The findings could help in the development of new treatments for depression and schizophrenia. Read More
Using mouse models, researchers seeded alpha-synuclein aggregates in gut neurons and discovered the clumps can travel to neurons in the brain. Read More
Novelty directly activates the dopamine system and enhances associative learning. The findings have implications for the development of new machine learning technologies and educational strategies. Read More
New findings about dopaminergic neurons in the striatum could have implications for treating Parkinson's disease and Tourette syndrome. Read More
