The dynamics of using of stabilized motor defensive conditioned reflex of active avoidance in "shuttle-box" in rats after total influence of high energy electrons and of gamma-rays in doses 5-100 Gy were investigated. The quality structure of higher nervous activity disturbances after the influence of these kinds of ionizing radiation was identical. Therefore the tendency to disturbances aggravating after the electron radiation influence in the periods of the initial depression and of relatively normalization was revealed, especially after the irradiation in dose 50 Gy. The effective compensation of the functional disturbances in the central nervous system at the first 5-10 min after irradiation was after influence of electron radiation in doses about 30 Gy and after the influence of gamma-radiation in doses about 50 Gy. The irradiation of rats in doses 10 Gy and 5 Gy caused qualitative different dynamics of radiation disturbances in rats higher nervous activity. The differences in rats higher nervous activity after influence of electron and of gamma-radiation in these doses did not manifest distinctly.
研究了在大鼠接受5 - 100 Gy剂量的高能电子和γ射线全面照射后，其在“穿梭箱”中主动回避的稳定运动防御性条件反射的使用动态。在这些种类的电离辐射影响后，高级神经活动紊乱的质量结构是相同的。因此，揭示了在初始抑郁期和相对正常化期电子辐射影响后紊乱加剧的趋势，尤其是在50 Gy剂量照射后。在照射后最初的5 - 10分钟，剂量约30 Gy的电子辐射影响和剂量约50 Gy的γ辐射影响后，中枢神经系统功能紊乱得到有效补偿。10 Gy和5 Gy剂量照射大鼠导致大鼠高级神经活动中辐射紊乱的定性不同动态。在这些剂量下，电子辐射和γ辐射影响后大鼠高级神经活动的差异没有明显表现出来。
