Questiоns 23-25: A reseаrch grоup is interested in the pоssible role of the nicotinic аcetylcholine receptor (nAChR) α(7) subtype in mitigаting ethanol-induced ataxia. The effect of an intracerebellar infusion of PNU-282987 (an α(7) agonist; 2.5ng, 25ng, 250ng and 2.5μg) was evaluated on ethanol (2 g/kg; i.p.)-induced ataxia in balb/c mice. Ataxia was evaluated by assessing each animals time spent on the Rotorod. 30 animals were surgically implanted with intracerebellar cannulae 2 weeks prior to Rotorod training. One week following training, on trial 1, animals were injected with ethanol and Rotorod performance assessed 30 min later. The following day, on trial 2, all animals were injected with ethanol 10 min following an infusion of 2.5ng PNU-282987 and Rotorod performance assessed 30 min later. On trial 3 all animals were injected with ethanol 10 min following an infusion of 25ng of PNU-282987 and Rotorod performance assessed 30 min later. On trial 4 all animals were injected with ethanol 10 min following an infusion of 250ng of PNU-282987 and Rotorod performance assessed 30 min later and on trial 5 all animals were injected with ethanol 10 min following an infusion of 2.5μg of PNU-282987 and Rotorod performance assessed 30 min later. Ethanol-induced ataxia was attenuated following PNU-282987 microinfusion in a dose-dependent manner, with higher doses of PNU-282987 resulting in less ataxic symptoms. How many levels are there of the independent variable?
