Averaged evoked potentials: event related potentials (ERPs) and their applications.
Endogenous potentials are evoked responses that occur independent of the stimulus evoking them. They are related to different aspects of information processing. Two types of event related potentials (ERPs) are recorded, the P300 wave and contingent negative variation (CNV). The P300 wave is the most frequently studied factor in various clinical diseases and also for neurological research. Diffe...
متن کاملEvent related evoked potentials in hypertensive subjects.
Cognitive functions were assessed in hypertensive and sex and age matched healthy controls using auditory event related evoked potential 'odd ball' paradigm. The N2 and P3 latencies in the hypertensive subjects were significantly delayed as compared to controls. There was also correlation of blood pressure (BP) with N2 latency in hypertensive group. These findings suggest that cortical neurophy...
متن کاملP3 event related evoked potentials in pregnancy.
Cognitive function using P3 auditory event related evoked response was examined in 18 pregnant women of age group 18-25 years (Mean 21.78 +/- 2.1). P3 was obtained from scalp electrodes at CZ, PZ referenced to ear lobules during a task in which the subjects concentrated and pressed the button on hearing high pitched rare clicks in a train of low-pitched frequent and high pitched rare clicks. La...

متن کاملBrainstem Auditory Evoked Potentials
Brainstem auditory evoked potentials (BAEPs) are electrical field potentials generated by stimulation of the auditory pathways. With repetitive auditory stimulation, reproducible electrical potentials can be elicited and recorded from scalp electrodes. These waves are generated by specific brain regions and occur at predictable intervals. Clinically, this neurophysiological property is useful t...
