Statistical background characteristics and impulse activity of some fibres of the optical tract evoked by light flashes were compared before and after stimulation of the preoptic hypothalamic region in listenin-immobilized rabbits. It was shown that the influence of the high frequency preoptical hypothalamus stimulation correlates with the pattern of responses to light flashes observed when recording from the optical tract fibres. In most cases the preoptical hypothalamus stimulation caused an increase of the background activity and facilitation of responses to light flashes. Phasic response to a light flash with short latency (42 ms), consisting of a long train of pulses and tonic responses with long latency (155 ms) were facilitated to a greater extent. The facilitation of short-latent (35 ms) phasic responses to a light flash consisting of a short train of phases after the preoptical hypothalamus stimulation was not clearly pronounced or was inhibited.
在听觉固定的家兔中，比较了视前下丘脑区域刺激前后，由闪光诱发的视束某些纤维的统计学背景特征和冲动活动。结果表明，高频视前下丘脑刺激的影响与从视束纤维记录时观察到的对闪光的反应模式相关。在大多数情况下，视前下丘脑刺激导致背景活动增加，并促进对闪光的反应。潜伏期短（42毫秒）的对闪光的相位反应，由一连串长脉冲组成，以及潜伏期长（155毫秒）的紧张性反应，在更大程度上得到促进。视前下丘脑刺激后，对由短串相位组成的闪光的潜伏期短（35毫秒）的相位反应的促进作用不明显或受到抑制。
