An overview of nerve systems, impulse transmission, neurotransmitters, the brain, and the rest of the nervous system. ... Changed polarity of the membrane, the action potential, results in propagation of the nerve impulse along the membrane. An action potential is a temporary reversal of the electrical potential along...

In the nerve membrane there are several types of channels, each of which is selective to a specific ion, such as Na+ or K+. Therefore the situation of zero net flow across the membrane does not depend on one particular ion concentration gradient but it involves the concentration of the other permeant ions and...

Nerve impulses have a domino effect. Each neuron receives an impulse and must pass it on to the next neuron and make sure the correct impulse continues on its path. ... Figure 1: Transmission of a nerve impulse: Resting potential and action potential.

Among his earliest achievements were experiments that challenged vitalism, microscopic studies on the structure of the nerve cell and its processes, and the first reasonable estimates of the speed of nerve transmission based on physiological experiments.
