Closely related subtypes of dopamine-releasing neurons may play entirely separate roles in processing sensory information, depending on their physical structure. New research from the Institute of ...

Biology textbooks may need a revision, say Johns Hopkins Medicine scientists, who present new evidence that an armlike structure of mammalian brain cells may be a different shape than scientists have ...

Axons are the brain’s information highways, transporting cellular cargo, chemical signals, and electrical impulses to other cells. These “roads” are typically depicted as smooth and cylindrical, with ...

Neurons, the cells in brains and spinal cords that make up the central nervous system, communicate by firing electrical pulses. But scientists have found hints that neurons may transmit light as well, ...
