Abstract

In the present study, ongoing and evoked activity of antidromically identified trigemino-thalamic tract (TGT) neurons was examined over the sleep-wake cycle in cats. There was no difference in the mean spike discharge rate of TGT neurons when quiet sleep (QS) and active sleep (AS) were compared with wakefulness (W). However, tooth pulp-evoked responses of TGT neurons were decreased during AS when compared to W. Conversely, the responses of TGT neurons to air puff activation of facial hair mechanoreceptors reciprocally increased during AS when compared to W. The present data demonstrate that ascending sensory information emanating from distinct orofacial areas is differentially modified during the behavioral state of AS. Specifically, the results obtained suggest that during AS, sensory information arising from hair mechanoreceptors is enhanced, whereas information arising from tooth pulp afferents is suppressed. These data may provide functional evidence for an AS-related gate control mechanism of sensory outflow to higher brain centers.

摘要

在本研究中，我们在猫的睡眠-觉醒周期内检测了经逆向鉴定的三叉丘脑束（TGT）神经元的持续活动和诱发活动。将安静睡眠（QS）和主动睡眠（AS）与清醒状态（W）相比较时，TGT神经元的平均放电率没有差异。然而，与W相比，TGT神经元在AS期间对牙髓刺激的反应有所降低。相反，与W相比，TGT神经元在AS期间对面部毛发机械感受器的吹气激活反应则相应增加。目前的数据表明，在AS行为状态期间，源自不同口面部区域的上行感觉信息受到不同程度的改变。具体而言，所获得的结果表明，在AS期间，源自毛发机械感受器的感觉信息增强，而源自牙髓传入神经的信息则受到抑制。这些数据可能为与AS相关的感觉信息向高级脑中枢输出的闸门控制机制提供功能证据。
