Abstract

Rats were tested on 6 measures of swimming behavior 1, 2 and 4 weeks after sham operations or bilateral motor cortex lesions that damaged the forelimb areas and axons controlling the axial musculature. Rats with lesions performed more forelimb kicks and showed larger body angles than control animals. Number of hindlimb kicks and speed were within normal limits. Thus, some measures of swimming can be affected by small motor cortex lesions that spare the hindlimb projections.

摘要

在假手术或双侧运动皮层损伤（损伤了控制前肢区域和轴向肌肉组织的轴突）1、2和4周后，对大鼠进行6项游泳行为测量。与对照动物相比，有损伤的大鼠前肢踢腿次数更多，身体角度更大。后肢踢腿次数和速度在正常范围内。因此，一些游泳测量指标可能会受到保留后肢投射的小运动皮层损伤的影响。
