A novel theoretical framework for mathematically modeling nerve cells has illuminated for the first time how small synaptic impulses enable non-linear information processing in the brain. Reported in ...

Researchers have achieved patch-clamp studies of an elusive part of mammalian myelinated nerves called the Nodes of Ranvier. At the nodes, they found unexpected potassium channels that give the ...

The myelin sheath is a protective covering that surrounds fibers called axons, which are the long thin projections that extend from the main body of a nerve cell or neuron. This sheath is composed of ...

It's surprisingly difficult to pinpoint what a given nerve is doing at any given moment. The electrochemical dance of neuronal function never stops, and it's synced to the beat of the default mode ...

(1) A nerve impulse arrives. (2) This causes calcium ion channels to open, resulting in an influx of calcium ions in the terminal. (3) This causes synaptic vesicles to fuse with the terminal membrane, ...

Researchers at the Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute at the Texas Children’s Hospital have uncovered a new cell type in the human brain. The team ...

THE observations reported here were made in the course of preliminary experiments concerned with the electrical changes which vagal and sympathetic nerve impulses produce in the pace-maker region of ...
