Expected waveforms. All plots were modified and reproduced with permission from the publishers. (A) The auditory-evoked potential (AEP) for stop (/d/, /t/) consonant-vowel pairs exhibits a small N100 potential followed by a larger P200 potential. Variation in timing will occur depending on the stimulus type and in the presence of noise83. (B) Vowels and consonants each produce a unique waveform84, such that the overall shape is dependent on the contribution of each to the waveform. (C) The shape of the TMS-evoked potential (TEP) will differ according to the cortical region targeted. Whether TMS creates an excitatory or inhibitory response can be observed in the shape of the resulting TEP. In the motor cortex, greater activity between 25-125 ms accompanies excitatory paradigms85. This figure illustrates the characteristic shape of the waveform for each type of neural response in the line and its standard deviation in the darker envelope.
