Abstract： 本工作研究猴运动前区(PM)皮层神经元在视觉图形引导的有序运动行为(作者称之为FRS[1])中的放电活动,并与在依靠记忆信息完成的空间顺序行为(MSS)中的活动作了比较.为此训练了三只猴同时学会FRS和MSS任务.对111个神经元的统计分析表明,它们在FRS和MSS暗示期中发生放电频率变化的均有一半以上,反应期里有放电频率变化的比例也很高;图形期里,FRS中的比例比MSS中的高出很多.它们对不同运动顺序呈现明显的选择性.对在动物完成FRS和MSS任务的相同运动顺序时放电活动增加的那些神经元所做的比较分析表明,它们在图形期里与FLS的关系要比MSS密切;在MSS的暗示期或图形期里反应潜伏期要比FRS长.以上结果说明背外侧PM区不仅参与MSS行为也参与FRS行为,它可能是功能上不同于PM其它部分的又一个亚区.从细胞反应潜伏期的分析结果推测,参与FRS和MSS行为的神经通路不完全相同,背外侧PM是参与FRS和MSS行为的神经网络中的一个共享结构.
