Since January 2020 Elsevier has created a COVID-19 resource centre with free information in English and Mandarin on the novel coronavirus COVID-19. The COVID-19 resource centre is hosted on Elsevier Connect, the company's public news and information website. Elsevier hereby grants permission to make all its COVID-19-related research that is available on the COVID-19 resource centre - including this research content - immediately available in PubMed Central and other publicly funded repositories, such as the WHO COVID database with rights for unrestricted research re-use and analyses in any form or by any means with acknowledgement of the original source. These permissions are granted for free by Elsevier for as long as the COVID-19 resource centre remains active.

Fig. 2 — Precise time courses of interhemispheric facilitation and inhibition. (A) IHF and (B) IHI (N = 12) tested at ISIs 1.5 ms before and 0.5 ms after the time points for maximal facilitation and inhibition with 0.1 ms resolution. Abscissa indicates the ISI. Time 0 was defined as the ISI with maximal IHF or IHI in each subject. Ordinate indicates the magnitude of IHF (open circle) or IHI (filled circle). It is expressed as a percentage difference between motor evoked potential amplitude induced by CS-TS paired-pulse stimulation and that induced by TS alone (defined as 100%). The value for IHF is positive and that for IHI is negative. ∗P < 0.05, ∗∗P < 0.01, post hoc paired t-test with Bonferroni’s correction comparing motor evoked potential with paired-pulse stimulation to that with TS alone. CS = conditioning stimulus; IHF = interhemispheric facilitation; IHI = interhemispheric inhibition; ISI = interstimulus interval; TS = test stimulus.
