SB-200646A (4 μM) abolishes the ethanol-induced increase in miniature inhibitory postsynaptic current (mIPSC) frequency and had no effect on basal mIPSC frequency.
SB-200646A (20 mg/kg; intravenous injection; daily; for 21 days; male albino Sprague-Dawley rats) treatment significantly decreases the number of spontaneously active ventral tegmental area (VTA) dopaminergic neurons.
The i.v. administration of 4-16 mg/kg of SB-200646A significantly increases the firing rate and % events as bursts in spontaneously active VTA dopaminergic neurons and significantly increases the % events as burst in substantia nigra pars compacta (SNC) dopaminergic neurons.
| Animal Model: | Male albino Sprague-Dawley rats (200-225 g at the beginning of treatment and 300-350 g at the time of the experiment) |
| Dosage: | 20 mg/kg |
| Administration: | Intravenous injection; daily; for 21 days |
| Result: | Significantly decreased the number of spontaneously active ventral tegmental area (VTA) dopaminergic neurons. |
