Using light- and electron-microscopic techniques, a quantitative histological study of the rat saphenous nerve has been carried out. The distribution of myelinated fibre diameters was bimodal; while that of the unmyelinated axons was unimodal. The variation of myelin sheath thickness with axon diameter was non-linear; two straight lines were found to fit(More)
Contralateral and ipsilateral cortical somatosensory evoked potentials to selective activation of different diameter sural nerve fiber groups were recorded in cats. Activation of alpha fibers evoked a well defined positive-negative primary potential at the contralateral somatosensory area II. Activation of delta fibers in addition to alpha fibers resulted(More)
Optimizing a neural network to improve classification performance rainstem Auditory Evoked Potentials B (BAEPs) are considered the most objective measure currently available with which to determine the functional integrity of the peripheral auditory nervous system. BAEPs are the early portion of the electrical activity of the brain in response to a brief(More)
Five far-field components were identified preceding the cortical wave in response to the stimulation of the A beta fibers of the sural nerve. When A delta activity was also included in the afferent volley, a second cortical wave and additional far-field potentials were recorded. Upon blocking the A beta fiber activity and thus isolating the peripheral input(More)
