P3 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. Latency and amplitude of P3 was compared with age matched twelve non-pregnant women. There was a significant increase in P3 latency and amplitude in the pregnant group suggesting that changed milieu of pregnancy does affect generators of P3 component of event related potential and cognitive functions of the brain.
