Click-evoked responses from the exposed intracranial portion of the eighth nerve during vestibular nerve section: bipolar and monopolar recordings.
We compare the click-evoked compound action potentials from the exposed intracranial portion of the eighth nerve using bipolar and monopolar recording electrodes in patients undergoing vestibular nerve section. It is assumed that a bipolar recording electrode will only record propagated neural activity in the auditory nerve, whereas a monopolar recording electrode may in addition record electri...
متن کاملAuditory-evoked far fields averaged from the scalp of humans.
AVERAGING, when used to extract extremely small signals from relatively high levels of background noise, allows detection of evoked potentials at surprisingly large distances from the site of neuronal activity. In animals, volume-conducted potentials from brain-stem auditory structures can be recorded throughout the brain (Grinnell, 1963; Bullock et ah, 1968; Jewett, 1970) and even from the sca...
متن کاملCombined effects of recovery period and stimulus intensity on the human auditory evoked vertex response.
Averaged auditory evoked vertex responses were obtained from eight normal-hearing sub~cts in response to 32 monaural 1000-Hz tone bursts at 30 combinations of recovery period and stimulus intensity. From curves describing N1-P2 peak-to-peak amplitudes, an equation was derived that describes the combined effects of recovery period and stimulus intensity on evoked response ampfitude. The results ...
متن کاملA 40-Hz auditory potential recorded from the human scalp.
Computer techniques readily extract from the brainwaves an orderly sequence of brain potentials locked in time to sound stimuli. The potentials that appear 8 to 80 msec after the stimulus resemble 3 or 4 cycles of a 40-Hz sine wave; we show here that these waves combined to form a single, stable, composite wave when the sounds are repeated at rates around 40 per sec. This phenomenon, the 40-Hz ...
متن کاملEffects of intersignal interval on the human auditory evoked response.
Average evoked responses were recorded from human vertex in response to tone pulses presented at intersignal intervals (ISI) ranging from 0.25 through 10 sec. Tone pulses were 20 msec in duration with 20-msec rise and decay times. Frequencies investigated were 500, 1000, and 2000 Hz. Response amplitude was found to be a linear function of logx0ISI. Response latency did not change significantly ...
