In 1921, Otto Loewi woke from a dream with the idea for an experiment that proved nerves communicate using chemicals, not just electricity. By showing that stimulating one frog’s heart released a ...

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 of nerve signals ...

New research describes a key molecular mechanism in nerve fibers that ensures the rapid conductance of nervous system impulses. New research from the University of North Carolina at Chapel Hill School ...

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, ...

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 of nerve signals to and from the brain ...

At first glance, nerve cells would appear to be energy hogs. The brain accounts for only about two percent of a human's body mass, but burns through 20 percent of its energy budget. But transmitting ...

Due to their simple body structure with a limited number of cell types, freshwater polyps (Hydra) can be used to study many fundamental processes of life. In recent years, Hydra has also experienced a ...

Multiple sclerosis is an autoimmune disease in which the body's own immune cells attack myelin in the brain and spinal cord. Myelin or the myelin sheath is a protective layer of fat that insulates ...

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), ...

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 ...
