title: [The auditory evoked potentials of the brain stem in the guinea pig].
abstract: The examination of the standard waves' amplitude and latency of the brain stem auditory evoked response (BAEP) was performed in 20 guinea pigs (males and females, weighing 250 to 300 g). According with the relative loudness of stimuli (90, 70, 50, 30, 10 dB SPL), the latency of BAEP waves was larger (t1 = 0.2 msec), but the conductance time between P1 to P5 was constant (3.1 to 3.6 msec). The highest wave of BAEP was P2 with an amplitude: 90 dB SPL, U = 6.5 +/- 1.2 microV; 70 dB SPL, U = 4.3 +/- 1.0 microV; 50 dB SPL, U = 3.5 +/- 0.6 microV; 30 dB SPL, U = 2.0 +/- 0.4 microV.
