Nitric oxide (NO) is implicated in the acute locomotor activating effects of some addictive drugs such as amphetamine, caffeine, and PCP, but has not been investigated in the case of toluene. This study determined the contribution of the NO-cyclic GMP (cGMP) pathway to locomotor stimulant effects of toluene. Locomotor activity was measured for 90 min(More)
Toluene exposure during brain growth spurt has been shown to elevate the seizure susceptibility induced by N-methyl-d-aspartate (NMDA). In the present study, behavioral responses to NMDA antagonists were studied to determine whether neonatal toluene exposure produces residual deficits in the NMDA glutamatergic system controlling behaviors. We also(More)
Toluene has been reported to antagonize the function of N-methyl-D-aspartate (NMDA) receptors. In this study, the effects of neonatal toluene exposure on NMDA receptors in primarily cultured cerebellar granule neurons were examined. Sprague-Dawley rats were treated with toluene (0, 200, 500, and 1000 mg/kg, i.p.) from postnatal day (PN) 4 to PN 7. Under(More)
Toluene, an industrial organic solvent, is voluntarily inhaled as drug of abuse. Toluene has been shown to inhibit the nicotinic acetylcholine receptors. Nicotinic receptors play an important role in brain development during brain growth spurt and early adolescence. The long-term effects of neonatal and adolescent toluene exposure on behavioral responses to(More)
