Losing the activity of a key ion channel in the brain may contribute to the buildup of a devastating and toxic protein responsible for the clumps of plaque that accumulate in Alzheimer's disease, a team of neurobiologists ...
Our brains are made of billions of neurons, which are connected forming complex networks. They communicate between themselves by sending electrical signals, known as action potentials, and chemical signals, known as neurotransmitters, ...

(Medical Xpress)—Sensory adaptation is a familiar phenomenon. Whether jumping into a cold pool, or driving through manure-laden air as you pass by a recently fertilized farm, an initially strong sensory experience generally ...
(Medical Xpress)—The smooth operation of the brain requires a certain robustness to fluctuations in its home within the body. At the same time, its extraordinary power derives from an activity structure poised at criticality. ...
For decades, scientists have dreamed of building computer systems that could replicate the human brain’s talent for learning new tasks.
