Impulse responses of neurons of the pigeon forebrain hyperstriatal part to stationary and moving visual stimuli were investigated. Particular attention was given to revealing a retinotopic projection in the region of visual representation in Wulst. It is shown that as the electrode moved gradually in the caudal direction in the region of visual projection of the hyperstriatum, the receptive fields of the neurons under observation displaced in the visual field in the opposite direction. The receptive fields of the ventral and dorsal hyperstriatum cells remain higher in the visual field and have larger diameters than the receptive fields of neurons of the accessory hyperstriatum. Neurons responses of the visual projection of the Wulst region depend on luminosity, size, speed and direction of the movement of the test-objects through the receptive field. The functional role of the retino-thalamo-telencephalic system in the visual integration in birds is discussed and a supposition is advanced on possibility to compare the Wulst region with striatal and frontal visual areas of the mammalian cortex.
研究了鸽子前脑上纹状体部分的神经元对静止和移动视觉刺激的冲动反应。特别关注揭示伍尔斯特视觉表征区域中的视网膜拓扑投射。结果表明，随着电极在纹状体视觉投射区域中逐渐向尾侧移动，所观察神经元的感受野在视野中向相反方向移位。腹侧和背侧纹状体细胞的感受野在视野中位置较高，且直径比副纹状体神经元的感受野大。伍尔斯特区域视觉投射的神经元反应取决于测试物体通过感受野的亮度、大小、速度和运动方向。讨论了视网膜 - 丘脑 - 端脑系统在鸟类视觉整合中的功能作用，并提出了将伍尔斯特区域与哺乳动物皮层的纹状体和额叶视觉区域进行比较的可能性假设。
