Abstract

Motor behaviors result from information processing that occurs in multiple neural networks acting at all levels from the initial selection of the behavior to its final generation. A long-standing research interest is how single neural networks can help generate different motor behaviors, that is, the origin of motor flexibility. Modern experimental techniques allow studying neural network activity during the production of multiple motor behaviors. Recent data provide strong evidence that the neural networks controlling insect legs are individually modified in task-dependent and finely tuned fashions. Understanding the mechanistic basis of these neural network modifications will be of particular interest in the upcoming years.

摘要

运动行为源于信息处理,该过程发生在多个神经网络中,作用于从行为最初选择到最终产生的各个层面。一个长期以来的研究兴趣是单个神经网络如何帮助产生不同的运动行为,也就是说,运动灵活性的起源。现代实验技术允许在多个运动行为的产生过程中研究神经网络活动。最近的数据提供了强有力的证据,表明控制昆虫腿部的神经网络以依赖于任务和精细调节的方式进行个体修改。在未来几年,理解这些神经网络修改的机制基础将特别有趣。
