Descriptor cronaxia
Scope note: La menor duración de un estímulo eléctrico en el que la amplitud umbral es el doble de la reobase - el mínimo para desencadenar un POTENCIAL DE ACCIÓN en cualquier momento. Es una medida de la excitabilidad del tejido nervioso o muscular, y es característico de los tipos y/o estado de las células nerviosas o musculares del tejido.
