Figure 8. Facilitation of activation of a population of motoneurons (VR discharges) by iPT stimuli combined with coPT and MLF stimuli during and after tDCS.

Figure 8

(A–G), Averaged records (n=20) of discharges of motoneurons from the S1 VR evoked by different combinations of iPT, coPT and MLF stimuli as in Fig. 7. Net contributions from iPT are indicated by lower traces - computer generated differences between records indicated to the left. Left panels, control records. Middle and right panels, records during the 7th period of tDCS and 30 min after its last application. (H), superimposed expanded records from (G), illustrating both increases in the discharges and the shortening of their latencies. (I), records of descending volleys from the cord dorsum. Arrows in (H) indicate strongest effects of tDCS. Arrows in (I) indicate MLF volleys followed by EPSPs shown in (H). For the time course of effects of tDCS see Fig. 9A–C.
