Abstract

The effect of vibration on spontaneous unit activity, oxygen consumption in cortical neurons and their responses to stimulation of posterior hypothalamus and vestibular Deiters' nucleus, were studied. Biphasic changes occurred in frequency of cortical unit activity and in the latter interrelationships with the level of oxygen consumption after 3-hour exposure to the vibration. The 15-day vibration enhanced the mean frequency of unit activity, facilitated the effect of subcortical neurons and eliminated bursts of discharges. The effect of long-term vibration upon cortical unit activity response to stimulation of subcortical structures was quite obvious.

摘要

研究了振动对自发单位活动、皮层神经元耗氧量及其对下丘脑后部和前庭代特氏核刺激反应的影响。在暴露于振动3小时后,皮层单位活动频率以及其与耗氧量水平的相互关系出现了双相变化。15天的振动增加了单位活动的平均频率,促进了皮层下神经元的作用,并消除了放电爆发。长期振动对皮层单位活动对皮层下结构刺激反应的影响非常明显。
