SICI, ICF, and LICI recorded from the left FDI muscle are expressed as percentages of the response to the CCS alone. IHI, recorded from the right FDI muscle, are expressed as percentages of the response to the test stimulus alone. IHI: elicited by CCS_1mV; CS–IHI: IHI_1mV in the presence of SICI, ICF, or LICI; IHI (adjusted CCS): elicited by a CCS adjusted to produce a 1 mV MEP response in the presence of intracortical inhibition or facilitation; CS–IHI (adjusted CCS): IHI_1mVCS2 in the presence of SICI, IHI_1mVCS10 in the presence of ICF, or IHI_1mVCS100 in the presence of LICI. The corresponding conditions are listed in parentheses.
