1 Pretreatment with the 5-HT-1A agonists (+)8-OH-DPAT (0.001-0.1 mg/kg) and LY274600 (0.3-3.0 mg/kg) either had no affect or exacerbated the nicotine-withdrawal-enhanced startle response. Nicotine 5-hydroxytryptamine receptor 1A Rattus norvegicus
2 Pretreatment with the 5-HT-1A antagonists NAN-190 (1-3 mg/kg), LY206130 (1-10 mg/kg), or WAY-100635 (0.1-1.0 mg/kg) blocked the increase in the startle response caused by nicotine withdrawal at doses that had no effect on baseline startle responses. Nicotine 5-hydroxytryptamine receptor 1A Rattus norvegicus
3 These data indicate that 5-HT-1A receptors play a role in the neurophysiology of nicotine withdrawal. Nicotine 5-hydroxytryptamine receptor 1A Rattus norvegicus
