摘　　要：采用离体脑片技术与电生理技术 ,观察记录蛤蚧端脑离体脑片 ADVRrl的自发电活动特性 .实验结果按放电形式和特征可归纳为随机发放、阵发排放、周期性排放 3种类型 .它们可能是 ADVRrl内某些完整回路或不完善回路或回路中的某一片段单位自发电活动的外在表现 ,也有可能是某一丛簇的整体电活动 .此外 ,ADVRrl总体自发水平较低 ,高发放单位数量较少 ,可能是 ADVRrl内部 GABA能神经元抑制的结果 .The spontaneous discharge of the rostrolateral area of ADVR (ADVRrl) in lizardGekko geckowas studied in vitro combined with the technique of electrophysiology.The discharges are classified according to their characteristics into three types:irregular,interval and periodical.It may be the responses of some complete,or incomplete,or partial circuit pathway,and also may be the spontaneous responses of some cluster cells in ADVRrl.Moreover,the total of spontaneous discharges is so lower that hard to record,which may be the inhibitory results of the GABA-engic cells in ADVRrl.
