[The effect of stressfully loud sound on motor asymmetry in rats].
In 43 female Wistar rats, a loud sound did not alter the asymmetry in behavioral tests even if is was loud enough to induce seizure. Under apomorphine test, the sound tended to decelerate the rotation, the asymmetry being preserved both in sound-activated and in sound-resistant subgroups. A shortening of the rotation onset latency occurred in sound-activated subgroup which may be associated with an increased permeability of the hemato-encephalic barrier following the sound-induced seizure.
