Differences between the distribution of SCP in persons of the same sex and age, but with different FMAs are observed both in the temporal areas, which seems to be the most logical, and in sagittal leads.
If right-handers at young and middle age have SCD in the left temporal region significantly higher than in the right, then left-handers of the same age have the opposite ratios of the potential level in the temporal areas. In left-handers, however, the hemispheric difference of SCP is somewhat smaller and the individual variability of this indicator is larger, as a result of which the hemispheric differences of SCP are not statistically significant. This corresponds to the lower lateralization of left-handers found in behavioral tests. Differences in the difference of SCP in the temporal regions of right-handed and left-handed people are significant.
