Figure 2. N100 TEP Amplitude Decreases with Age:

Figure 2

N100 amplitude decreases as a function of age after controlling for whether rMT was elicitable (<100% MSO) or supramaximal (>100% MSO). N100 TEP amplitude increases as a function of stimulation intensity within a given individual. rMT is used to normalize stimulation intensity across individuals, but this cannot be done for those with supramaximal rMTs. Consequently, subjects with supramaximal rMTs (triangles) have smaller N100 amplitudes than those with elicitable rMTs (circles). Age becomes a significant predictor of N100 TEP amplitude after stratifying by rMT.
