... The conduction of impulses between neurons operates under an “all-or-none” principle. This means that the magnitude of a neuron’s response to a stimulus is independent of the strength of that stimulus. When a single stimulus is strong enough to exceed a certain threshold potential, the neuron will f ...

... responses, and 2) it decreased the number of brain-invading, injury-producing, polymorphonuclear (PMN) leukocytes. PMNs gather around oxygen-deprived brain tissue following stroke and increase the amount of the damaged tissue. When a neuron is damaged, a chain of events is set in motion that drives ...
