Abstract

Motor training (during 3-6 months) of rats in a treadmill started at the age of 1 month, leads to statistically significant increase in the activity of neuronal populations in the visual cortex judged by both latencies of primary responses and recovery cycles of responses to paired stimuli. It has been found that the significance of functional changes following locomotor training is more manifest in the recovery cycles than in the latencies of primary responses. The comparison of locomotor training effects in the visual cortex with those in the sensorimotor cortex reveals a more pronounced modulating influence of environment on the visual cortex. However the differences in these functional changes are more evident by absolute (msec) than by relative (%) cues.

摘要

对1月龄大鼠在跑步机上进行运动训练(3至6个月期间),从初级反应潜伏期和对配对刺激反应的恢复周期判断,会导致视觉皮层中神经元群体的活动在统计学上显著增加。研究发现,运动训练后功能变化的显著性在恢复周期中比在初级反应潜伏期更明显。将视觉皮层中的运动训练效果与感觉运动皮层中的效果进行比较,发现环境对视觉皮层的调节影响更为显著。然而,这些功能变化的差异以绝对(毫秒)指标比以相对(%)指标更明显。
