In result study of structural organization of neural receptive fields (RFs) and their different zones on the prestriate cortex level was shown that neural RFs in this area have hypercomplex structure and consist of some spatial different excitatory zones. Orientation and velocity selectivity and spatial-frequency characteristics of the excitatory zones of the same RF may differ between zones. The number of zones in RFs correlate with RF sizes: the more RF size the more zones number in them (r = 0.05, P < 0.02). About 66% of zones in RFs have approximately identical sizes (12-16 deg) and sizes those zones an dependence as from their number in RFs (r = 0.03, P > 0.05) as from the eccentricity (r = 0.3, P > 0.05). Zones in RF were distributed so that distance their centres was between 56-65 degrees (an average across all 60 degrees). If two or three zones were tested simultaneously the neuron changed own frequency and orientation tuning. Consequently the functional organization of neural RFs of prestriate cortex depend upon number simultaneously tested zones in spatial information processing. Was shown that important properties of prestriate cortex neurons is their ability to integrate and complex processing of spatial information across wide area of the visual field; in the prestriate cortex thus violate of straight retinotopical representation principle of visual field, characteristics of all investigated areas of visual system. The results represented in this review allow suppose that the structural and functional unit of cortex which make integration of spatial information from different compose this information is prestriate cortex neurons and not is no striate cortex modules. Consequently combined of neurons which make images description from different parts of visual field out of dependence of cortical area in turn integrate in neuron networks. Is known that neurons of any level have characteristics different of (from) characteristics of other levels visual system. The interaction of different elements of visual system form ultrastructure of RFs and their different zones in prestriate cortex, and ensure function of networks. So just on prestriate cortex neurons level appear whole system of surrounding world universe system of connections from different cortical areas which is morphological and functional base in process of spatial information integration RFs which have the central and peripheral representation.
在对视前区皮质水平上神经感受野（RFs）的结构组织及其不同区域的研究结果表明，该区域的神经感受野具有超复杂结构，由一些空间上不同的兴奋区组成。同一感受野的兴奋区的方向、速度选择性和空间频率特性在不同区域可能有所不同。感受野中的区域数量与感受野大小相关：感受野越大，其中的区域数量越多（r = 0.05，P < 0.02）。感受野中约66%的区域大小大致相同（12 - 16度），这些区域的大小与它们在感受野中的数量（r = 0.03，P > 0.05）以及与偏心率（r = 0.3，P > 0.05）无关。感受野中的区域分布使得它们中心之间的距离在56 - 65度之间（所有区域平均为60度）。如果同时测试两个或三个区域，神经元会改变自身的频率和方向调谐。因此，视前区皮质神经感受野的功能组织取决于在空间信息处理中同时测试的区域数量。研究表明，视前区皮质神经元的重要特性是它们能够在视野的广泛区域整合和复杂处理空间信息；因此，在视前区皮质中违反了视野的直接视网膜拓扑表征原则，而这是视觉系统所有研究区域的特征。本综述中呈现的结果表明，进行来自不同区域的空间信息整合并构成此信息的皮质结构和功能单元是视前区皮质神经元，而非纹状皮质模块。因此，从视野不同部分进行图像描述而不依赖于皮质区域的神经元组合依次整合到神经元网络中。已知视觉系统任何水平的神经元都具有与其他水平不同的特征。视觉系统不同元素的相互作用形成了视前区皮质中感受野及其不同区域的超微结构，并确保了网络的功能。所以正是在视前区皮质神经元水平上出现了来自不同皮质区域的整个周围世界宇宙连接系统，这是在具有中央和周边表征的感受野进行空间信息整合过程中的形态学和功能基础。
