Flash and click evoked potentials were recorded from the same electrode in the midbrain reticular formation of hooded rats. Animals were given i.p. injections of saline, 0.25, 0.5, 1.0 or 2.0 g ethanol/kg body wt. on separate days. The click data demonstrated both a biphasic effect of ethanol and an enhanced sensitivity relative to the flash data. It is suggested that differing evoking stimuli may sample the activity of functionally different populations of neurons within the reticular formation.
在有头罩大鼠的中脑网状结构中，从同一电极记录闪光和点击诱发电位。在不同日期给动物腹腔注射生理盐水、0.25、0.5、1.0或2.0克乙醇/千克体重。点击数据显示乙醇有双相效应，且相对于闪光数据敏感性增强。提示不同的诱发刺激可能对网状结构内功能不同的神经元群体的活动进行采样。
