| Abstract | Status epilepticus (SE) was induced for 40 min by flurothyl in well oxygenated rats. This insult resulted in selective destruction of up to 65% of the substantia nigra pars reticulata. We investigated the short and long term behavioral effects of this damage. No deficits were observed in sensorimotor reactivity, locomotor coordination, spontaneous or apomorphine-stimulated locomotor activity in the rats with induced epilepsy. However, these rats exhibited a long-lasting enhancement of amphetamine-stimulated locomotor activity. We propose that this selective impairment is caused by the necrosis of the pars reticulata. This damage might lead to deficient regulation either of mesostriatal dopamine neurons innervating nc. accumbens, or of neurons in the mesencephalic reticular formation mediating the locomotor response initiated in the nc. accumbens. |
