Frontal Cortex Control of Remembered Movement Sequences

罗纳德·凯特纳博士将研究两个基本问题：1)额叶皮质区域如何控制手臂对空间中一系列目标的快速运动；2)这些序列是如何在运动开始前的一段延迟时间内存储在短期记忆中的？他的基本方法将是从训练有素的猕猴额叶皮质中的单个神经元进行记录，这些猕猴执行一个简单的手臂运动任务。他收集的数据和之前收集的数据将使凯特纳博士能够开发和测试额叶皮质功能的数学模型。这项工作很重要，因为它将使我们更好和更详细地了解手臂运动是如何从皮质启动再生的。

Dr. Ronald Kettner will study two basic questions: 1) how dofrontal cortical areas control rapid arm movements to a sequenceof targets in space; and 2) how are these sequences stored inshort.term memory during a delay period before movementinitiation? His basic approach will be to record from singleneurons in the frontal cortex of well.trained rhesus monkeysperforming a simple arm movement task. The data he collectsalong with previously collected data will allow Dr. Kettner todevelop and test mathematical models of frontal corticalfunction. This work is important because it will give us abetter and more detailed understanding of how arm movements aregenerated from cortical initiation.
