Abstract
SummaryPurposeThe occurrence of unwanted afterdischarges (ADs) impedes cortical stimulation for mapping purposes. We investigated the safety of several stimulation paradigms.MethodsWe compared the incidence of ADs and behavioral responses of two stimulation frequencies (50 and 100 Hz), at two intensities (1 and 0.2 ms pulse widths).ResultsStimulation with 100 Hz was more likely to cause ADs than 50 Hz, and stimulation using 1 ms pulse width was more likely to cause ADs than 0.2 ms.ConclusionsStimulation using 50 Hz frequency with a pulse width of 0.2 ms might be safer during cortical mapping.
