September 5, 2024 by Eddy Duryea, University of Central Florida Description of plasmonic biosensor platform. (A) Schematic of integrated plasmonic biosensor platform. Top inset shows specificity of surface-functionalized DNA aptamer in presence of other interfering species, where the aptamer binds selectively to dopamine. Bottom inset shows a cartoon representation of the plasmonic biosensor. (B and...

DOI: 10.1016/j.ajpath.2024.02.014Recent evidence suggests that dopamine plays a crucial role in neural development. In a novel study, investigators demonstrated the link between disrupted developmental dopamine signaling and autism spectrum disorder (ASD)....

One characteristic of the disease is...
by Kyoto University Caption: Brain chemical dopamine enables adaptive reward pursuit to overcome lack of reward and ultimately obtain more rewards. Credit: KyotoU/Hiroko Uchida Dopamine has been known to increase when results are promising and decrease when expectations are not met. However, this role does not explain the ability to overcome disappointment. Now, researchers at Kyoto...
Dopamine is a neurotransmitter, a type of chemical that sends signals between nerves in the body. A dopamine deficiency may have links to several medical conditions, including depression, Parkinson’s disease, and attention deficit hyperactivity disorder (ADHD). Dopamine plays a part in controlling the movements a person makes, as well as their emotional responses. The right...
NETHERLANDS INSTITUTE FOR NEUROSCIENCE – KNAW IMAGE: PAVLOVIAN VERSUS OPERANT CONDITIONING EXPERIMENT CREDIT: NETHERLANDS INSTITUTE FOR NEUROSCIENCE A new study from the Netherlands Institute for Neuroscience brings together two schools of thought on the function of the neurotransmitter dopamine: one saying that dopamine provides a learning signal, the other saying that dopamine drives motivation. ‘But...
by Netherlands Institute for Neuroscience White noise (WN) is an aversive stimulus that lowers dopamine concentration in the nucleus accumbens core (NAC). (A) Left: example trajectory of a rat in the real-time place aversion test (30 min), in which entry into one quadrant (shaded), which was randomly determined prior to the session, led to 90...
