Figure 4. Effects of activeHIGH 1 Hz rTMS on pharyngeal motor cortex and hand motor cortex excitability.

Figure 4

Group mean ± s.e.m. (%) change in PMEP and TMEP amplitudes from baseline following activeHIGH (♦) 1 Hz rTMS over the stimulated stronger pharyngeal motor cortex. Inhibitory changes in PMEPs evoked from the stronger pharyngeal motor cortex can be seen immediately and for up to 45 min after active rTMS (*P ≤ 0.004, **P ≤ 0.001, post hoc t tests) but are not consistently seen in hand motor cortex (▪). Weaker pharyngeal motor cortex (▴) shows no change in excitability (P = 0.7).
