The stability of neuronal responses in the rabbit visual cortex to diffuse photic flashes presented in series with sufficiently long time intervals between them was studied in acute experiments. Three types of neuronal responses with different degree of stability were singled out. The stability was judged by the mean coefficient of correlation between post-stimulus histograms of spike activity. Negative correlations were found between the mean correlation coefficient and mean square deviations of latencies of primary and secondary activation and the pause in impulse activity in neuronal responses to a photic flash. Positive correlations between primary activation latencies and mean square deviations of other response parameters suggest a greater stability of responses with a short latency.
在急性实验中,研究了兔视觉皮层神经元对以足够长的时间间隔连续呈现的漫射光闪光的反应稳定性。区分出了三种具有不同稳定程度的神经元反应类型。通过峰值活动的刺激后直方图之间的平均相关系数来判断稳定性。在对光闪光的神经元反应中,发现平均相关系数与初级和次级激活潜伏期的均方偏差以及冲动活动暂停之间存在负相关。初级激活潜伏期与其他反应参数的均方偏差之间的正相关表明潜伏期短的反应具有更高的稳定性。
