Abstract

The EEG response in the chicken to repetitive photic stimulation was studied by frequency analysis and by the averaged response. Evoked responses were observable not only in stations along the visual pathway but also in broad areas apart from the visual pathway. The electrical activity in the archistriatum showed a marked response to flickering stimuli, indicating that this area is involved in the visual function in the chicken. In other telencephalic areas, photically evoked potentials could not be clearly demonstrated in the EEG records. In the hypothalamus and the nucleus rotundus of the diencephalon and in the nucleus reticularis superior of the mesencephalon, sinusoidal waves appeared during stimulation at 8-13/sec. No rhythmic after-discharge was observed following termination of photic stimulation. These finding are indicative of the difference of the visual response in the chicken from previously reported responses in other species.

摘要

通过频率分析和平均反应研究了鸡对重复性光刺激的脑电图反应。不仅在视觉通路沿线的部位可观察到诱发反应,在视觉通路以外的广泛区域也可观察到。古纹状体中的电活动对闪烁刺激有明显反应,表明该区域参与鸡的视觉功能。在其他端脑区域,脑电图记录中不能清楚地显示光诱发电位。在间脑的下丘脑和圆核以及中脑的上网状核中,在8 - 13次/秒的刺激期间出现正弦波。光刺激终止后未观察到节律性后放电。这些发现表明鸡的视觉反应与先前报道的其他物种的反应存在差异。
