summating potential
summating potential Summating potential is a waveform peak in click-evoked electrocochleography that reflects activity generated by hair cells in the cochlea.
Summating potential is a waveform peak in click-evoked electrocochleography that reflects activity generated by hair cells in the cochlea. In this source, it is considered alongside the action potential from cochlear neurons, and the SP/AP ratio is used as a possible sign of hidden hearing loss related to selective neural damage.
