When we learn a new skill, the brain has to decide—cell by cell—what to change. New research from MIT suggests it can do that ...
For at least six decades, neuroscientists have been arguing over a big, foundational question: Do adult brains make new neurons? This process of “neurogenesis” had been shown in other adult animals, ...
To think, feel, talk and move, neurons send messages through electrical signals in the brain and spinal cord. This intricate communication network is built of billions of neurons connected by synapses ...
A pair of new studies have provided fresh evidence in the long-running scientific debate—and the result could be ...
Overactivation of dopamine neurons may directly drive their death, explaining why movement-controlling brain cells degenerate in Parkinson’s. Mice with chronically stimulated neurons showed the same ...
Drug addiction carries an extremely high risk of relapse, as cravings can be reignited by minor stimuli even long after one has stopped using. Previously, this phenomenon was attributed to a decline ...
