fMRI captures brain oxygen levels (BOLD) as a proxy for local neuron signaling—higher levels mean more brain activity. The head needs to keep very still throughout the scans to avoid blurring. That’s ...

Although neurons are considered the basic units of the brain and nervous system, they do not do all the work. Glia are a non-neuronal category of cells that do not transmit electrical signals but ...

A new technique reveals cells’ precise locations and functions in the brain. Its developers have already used it to identify a previously unknown neuron type. Dan is a News Editor at The Scientist. He ...

Neuroscience examines the structure and function of the human brain and nervous system. Neuroscientists use cellular and molecular biology, anatomy and physiology, human behavior and cognition ...
