Abstract

These studies demonstrate the presence of the MLR in the rat brain. Controlled locomotion on a treadmill could be induced by low level stimulation (less than 50 microA) of an area in the posterior midbrain following a precollicular-prenigral brainstem transection. This area included the lateral part of the cuneiform nucleus and anterior as well as posterior portions of the pedunculopontine nucleus. In addition, the presence of a subthalamic locomotor region in the fields of Forel was determined in rats after prethalamic transections.

摘要

这些研究证明了中脑网状结构(MLR)在大鼠脑中的存在。在脑桥前-脑桥前脑干横断后,通过对中脑后部一个区域进行低水平刺激(小于50微安),可诱发大鼠在跑步机上进行可控运动。该区域包括楔状核的外侧部分以及脚桥核的前部和后部。此外,在丘脑前横断后的大鼠中,确定了Forel区存在丘脑底运动区。
