扫视(眼睛的高速共轭旋转)的功能是将选定视觉目标的图像带到视网膜上含有高密度光感受器的区域。最近的综述(罗宾逊1981 a,Fuchs等1985)记录了在描述控制这些快速、精确运动的神经信号方面取得的进展。这些论文从运动神经元的角度考虑文献,强调脑干神经元与支配眼外肌的运动神经元池具有相对直接的突触连接,从而产生命令信号。在这篇综述中,我们总结了什么是已知的扫视命令信号发现在一个更中心的点-上级丘(SC)。利用这些信息以及运动学参数,我们讨论了将丘信号转换为运动前神经元池所需的信号所需的转换。此外,我们认为其他脑干神经元的功能特性的背景下所需的转换。
Saccades (high velocity, conjugate rotations of the eyes) function to bring the image of selected visual targets onto regions of the retina containing a high density of photoreceptors. Recent reviews (Robinson 1981a, Fuchs et al 1985) have documented the progress made in describing the neural signals controlling these rapid, precise movements. These papers considered the literature from the perspective of the motoneuron, emphasizing the generation of command signals by brainstem neurons having relatively direct synaptic connections with the motoneuron pools innervating the extraocular muscles. In this review, we summarize what is known about saccadic command signals found at a more central point-the superior colliculus (SC). Using this information as well as kinematic arguments, we discuss the transformations required to convert collicular signals into those needed by premotor pools of neurons. Also, we consider the functional properties of other brainstem neurons in the context of the required transformations.
