Human summating potential using continuous loop averaging deconvolution: Response amplitudes vary with tone burst repetition rate and duration [PDF]

open access: yes, 2017
Electrocochleography (ECochG) to high repetition rate tone bursts may have advantages over ECochG to clicks with standard slow rates. Tone burst stimuli presented at a high repetition rate may enhance summating potential (SP) measurements by reducing ...
