Two varieties of barbiturate-induced EEG spindles are recognized. Type I originates subcortically but recent data suggest that type II spindles are triggered by type I at the cortical level. This is based on a temporal relationship between the two spindle types in the gross electrocorticogram. In the present study no such relationship could be found except possibly in light anesthesia. These results fail to confirm the only data supporting a cortical mechanism underlying type II spindles.
巴比妥类药物诱导的脑电图纺锤波有两种类型。I型起源于皮层下，但最近的数据表明，II型纺锤波是由I型在皮层水平触发的。这是基于两种纺锤波类型在总体皮层电图中的时间关系。在本研究中，除了可能在浅麻醉状态下，未发现这种关系。这些结果未能证实支持II型纺锤波存在皮层机制的唯一数据。
