RAMIREZ ARISTEGUIETA, Luis Miguel. Evaluation of the Effects of Various Intensities of Nerve Stimulation on the Scale of the Response in Different Species. Int. J. Morphol. [online]. 2010, vol.28, n.1, pp.227-238. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022010000100033.

Nervous behaviour by electrical stimulation has been widely studied since 1840, times that initiated the comprehension of the conduction velocity and nerve's amplitude responses in animals. The amplitude response in nerve segments electrically stimulated is generated by the result of composed action potentials. This research pretended to study the nerve responses to evoked potentials in human in vivo (ulnar nerve) and in vitro in animals (Bufus marinus) in sciatic nerve. Electrical stimulation resulted in rising responses of heterogeneous quality inter and intra-species. Mechanisms involved in each response are examined.

Palavras-chave : Composed action potential; Stimulation electrode; Register electrode; stimulation impulse; Intensity of charge displaced.
