Fig. 4. Threshold-tracking transcranial magnetic stimulation short-interval intracortical inhibition (SICI) results for all groups: across all interstimulus intervals (A) and for the peak interstimulus interval of 3 ms (B). Error bars indicate SEM values. ALS: amyotrophic lateral sclerosis, bvFTD: behavioral-variant frontotemporal dementia, MND: motor neuron disease, SEM: standard error of the mean.
