Novelty speeds up learning thanks to dopamine activation

Brain scientists led by Sebastian Haesler (NERF, empowered by IMEC, KU Leuven and VIB) have identified a causal mechanism of how novel stimuli promote learning. Novelty directly activates the dopamine system, which is responsible ...

Parkinson's disease may start before birth

People who develop Parkinson's disease before age 50 may have been born with disordered brain cells that went undetected for decades, according to new Cedars-Sinai research. The research points to a drug that potentially ...

The pathway to Parkinson's takes a surprising twist

In neurodegenerative conditions like Parkinson's disease, a specific group of neurons start to die one by one, causing movement problems and other symptoms. Scientists have long focused on finding out why these neurons die. ...

Unraveling the brain's reward circuits

To some, a chocolate cake may spark a shot of pleasure typically associated with illicit drugs. A new study by Penn biologists offers some insights into that link, revealing new information about how the brain responds to ...

A new drug target for chemically induced Parkinson's disease

More than three decades ago, scientists discovered that a chemical found in a synthetic opioid, MPTP, induced the onset of a form of Parkinson's disease. In a new study led by scientists from the School of Veterinary Medicine, ...

Unexplored neural circuit modulates memory strength

Learning to avoid negative experiences requires an interplay of two distinct brain circuits, one to interpret "Yikes!" and drive learning, and the other, unexpectedly, to dial in the strength of that memory, a new fruit fly ...

Altered brain activity patterns of Parkinson's captured in mice

The tell-tale tremors of Parkinson's disease emerge from abnormal activity in a brain region crucial for voluntary movement. Using a mouse model of the disease, researchers at the Okinawa Institute of Science and Technology ...
