Nervous System Physiology

Medical Definition:	Functions and activities of the nervous system as a whole or with reference to the peripheral or the central nervous system.
Guide Notes:	GEN or unspecified; prefer specifics; DF: NERVOUS SYSTEM PHYSIOL
Previously Indexed:	Nervous System/physiology (1966-1997)

Nervous System Physiology Categories.

	Cerebrospinal Fluid Pressure - Manometric pressure of the cerebrospinal fluid as measured by lumbar, cerebroventricular, or cisternal puncture. Within the cranial cavity it is called INTRACRANIAL PRESSURE.
	Chronaxy - The shortest duration of an effective electrical stimulus to nerve or muscle tissue, having a strength equal to twice the minimum strength required for excitation. (Stedman's, 25th ed)
	Dominance, Ocular - The functional superiority and preferential use of one eye over the other. The term is usually applied to superiority in sighting (VISUAL PERCEPTION) or motor task but not difference in VISUAL ACUITY or dysfunction of one of the eyes. Ocular dominance can be modified by visual input and neurotrophic factors.
	Higher Nervous Activity
	Kindling (Neurology) - A phenomenon in which there is a relatively profound alteration in brain function resulting from repeated electrical or chemical stimulation and culminating in the appearance of electrographic and behavioral convulsions whenever the stimulus is re-applied. It is used as an experimental model for epilepsy.
	Neural Conduction
	Neural Inhibition
	Neuronal Plasticity - The capacity of the nervous system to change its reactivity as the result of successive activations.
	Neurosecretion
	Spreading Cortical Depression
