The receptors of neurotransmitters move very rapidly. This mobility plays an essential, and hitherto unsuspected, role in the passage of nerve impulses from one neuron to another, thus controlling the ...

COLUMBUS, Ohio – Scientists have solved a longstanding mystery of the central nervous system, showing how a key protein gets to the right spot to launch electrical impulses that enable communication ...

(Nanowerk News) Information coded as impulses is transferred from one neuron to its target at synapses. At these close neuron-neuron contacts the impulse opens voltage sensitive calcium channels ...

(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, ...

THE intimate nature of the nervous impulse has long been a subject for speculation by physiologists and psychologists. Simple models to explain the mode of transmission of an impulse along a nerve, ...

Researchers may finally have a better explanation for epilepsy, chronic pain and other conditions of the nervous system that have baffled the scientific world for decades. Neurons are the most basic ...

Nerve cells communicate with one another via synapses. Neuroscientists at the University of Zurich and ETH Zurich have now found that these connections seem to be much more powerful than previously ...

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 ...

DR. ALCOCK, in his recent paper at the Royal Society, finds the rate of transmission of nerve impulses in man to be 66 metres per second. Sir Michael Foster, in his “Physiology” (1888, part i. p. 76), ...

One of the greatest, relatively underappreciated, discoveries in all of science was the discovery of the nerve impulse in the 1930s by the British Lord Adrian. Adrian did win a Nobel Prize for his ...
