Dopamine neuron firing helps brain distinguish between rewarding and aversive eventsResearchers are one step closer to understanding the neurobiology that allows people to successfully learn motivated behaviors by associating environmental cues with rewarding outcomes, according to a study published yesterday in the Proceedings of the National Academy of Sciences' online Early Edition. Carlos Paladini, assistant professor of neuroscience at The University of Texas at San Antonio (UTSA) and...

The human brain's sensitivity to unexpected outcomes plays a fundamental role in the ability to adapt and learn new behaviors, according to a new study by a team of psychologists and neuroscientists from the University of Pennsylvania.Using a computer-based card game and microelectrodes to observe neuronal activity of the brain, the Penn study, published this week in the journal Science, suggests that neurons in the human substantia nigra, or SN, play a central role in reward-based learning,...

The melodious singing of birds has been long appreciated by humans, and has often been thought to reflect a particularly positive emotional state of the singer. In a new study published in the online, open-access journal PLoS ONE on October 1, researchers at the RIKEN Brain Science Institute in Japan have demonstrated that this can be true. When male birds sang to attract females, specific "reward" areas of their brain were strongly activated. Such strong brain activation resulted in a...

By Rothstein, Ted L Olanow, C Warren Shaking and slowness of movement may be the most obvious symptoms, but they are often not the most debilitating ones Parkinson's disease may not be an epidemic, but it's more common than you might think. Approximately 1,000,000 Americans suffer from the illness, with 60,000 new cases appearing each year in the United States alone. This neurodegenerative disorder, which is both progressive and incurable, usually begins around age 60, so neurologists...

New research has uncovered a fundamental cellular mechanism that may drive pathological drug-seeking behavior. The study, published by Cell Press in the July 31 issue of the journal Neuron, examines the brain's reward circuitry and details strikingly distinct influences of self-administered cocaine compared to natural rewards or passive cocaine injection. Dopamine (DA) neurons residing within the ventral tegmental area (VTA) of the brain are a key part of the brain's natural reward pathway...

A team of scientists from Princeton University has devised a new experimental technique that produces some of the best functional images ever taken of the human brainstem, the most primitive area of the brain.The scientists believe they may be opening the door to inquiries into a region that acts as the staging area for the brain chemicals whose overabundance or absence in other parts of the brain are at the root of many neuropsychiatric disorders, like addiction, schizophrenia and...

The midbrain, also known as the mesencephalon is the part of the brain most responsible for vision, motor control, arousal, temperature regulation, alertness and hearing. Formation and Orientation The midbrain is found under the cerebral cortex and above the hindbrain. The mesencephalon is not divided into any other portions of the brain unlike the other two vesicles that stem from the neural tube. There are four separate lobes on the side of the cerebral aqueduct within the...
