An Investigation of the Human Cortical Evoked Potential Under Conditions Of Monaural and Binaural Stimulation

Effects of Hearing Aid Amplification and Stimulus Intensity on Cortical Auditory Evoked Potentials

“…As the intensity of the stimulus increases, peak latencies decrease and peak amplitudes increase [Adler and Adler, 1989;Beagley and Knight, 1967;Botte et al, 1975;Bruneau et al, 1985;Butler et al, 1969;Khechinashvili et al, 1973;Martin and Boothroyd, 2000;McCandless and Best, 1966;Moore and Rose, 1969;Picton et al, 1977;Polich et al, 1988;Rapin et al, 1966;Roth et al, 1984;Spoor et al, 1969;Uziel and Seneclause, 1978]. The unaided results of this experiment are consistent with these published findings.…”

Study of the Human Auditory Cortices Using a Whole-Head Magnetometer: Left vs. Right Hemisphere and Ipsilateral vs. Contralateral Stimulation

“…that damage to the auditory cortex yields a deficit in the contralateral ear. This view is supported by electrophysiological evidence obtained from animal experiments [Rosenzweig, 1951], by intracortical recordings from the auditory cortex in humans during neurosurgical operations [Celesia, 1976], by EEG [Butler et al, 1969] and by magnetoencephalographic (MEG) measurements [Pantev et al, 1986;Hoke, 1988;Mäkelä, 1988;Mäkelä and Hari, 1990]. In the noninvasive EEG and MEG studies, determination of the lateralization of auditory responses was based upon the most prominent deflection of the slow auditory evoked potential or field, the N1m (M100), that evolves with a peak latency of about 100 ms after stimulus onset [for review see Hari, 1990].…”

Binaural interaction in auditory evoked potentials: Brainstem, middle- and long-latency components

“…5). There is evidence that both inhibition and excitation accompany binaural processes at the single cell level (Butler, 1969;Brugge et al, 1973;Moore, 1991). It is attractive to consider that the evoked potential changes accompanying binaural interaction are secondary to specific excitatory and inhihitory single unit events but must await evidence of such specific relationships.…”
