[Evoked potentials of the somatosensory regions of the brains of healthy subjects].
Somatosensory evoked responses were recorded in 37 healthy adults, male and female, at the age of 18-53. These responses were polyphasic aperiodic and consisted of 7-9 waves. The early components of the response were more marked in monopolar recording. Differences in the fluctuation of the latent periods and amplitudes were found as dependent on the age. Ipsilateral responses contrary to the contralateral ones were more variable, had a less amplitude and frequency of appearance of separate components. The latent periods of ipsilateral responses were longer (3-7 ms) as compared to the contralateral ones.
