Mouse studies offer new insights about cocaine’s effect on the brain

Newly discovered beetle species named after Rockefeller’s Daniel KronauerResearchers have determined how a specific protein regulates the brain’s response to cocaine. Their findings provide fresh insights into the neurobiology of addiction, and could lead to the development of better interventions and treatments.

Study offers insight on how a new class of antidepressants works

Study offers insight on how a new class of antidepressants worksThe experimental drugs target brain cells’ ability to respond to the chemical messenger glutamate, however, it has been unclear how they work. The recent discovery of a molecular amplification system helps explain how the drugs alter signaling in particular neurons to achieve an antidepressant effect. More »

A newly discovered molecular feedback process may protect the brain against Alzheimer’s

A newly discovered molecular feedback process may protect the brain against Alzheimer’s Researchers have identified within neurons a series of molecular interactions — known as a pathway — that can dampen the production of the Alzheimer’s protein amyloid-β. These results suggest a new route in the search for therapies for this degenerative disease. More »

Ritalin may cause changes in the brain’s reward areas

A common treatment for attention deficit/hyperactivity disorder, prescribed millions of times a year, may change the brain in the same ways that cocaine does, a new study in mice suggests. More »
