研究了具有一般联系的侧抑制型均匀神经场的斑图形成动力学。对单层神经场进行了处理，证明了有5种类型的模式动力学。场的动态的类型不仅取决于场内的相互联系，而且取决于给予场的同质刺激的水平。动力学的一个例子如下：固定大小的局部激发，一旦由刺激引起，即使在刺激消失后，也可以持久地保持在场中。它移动，直到它找到输入刺激的最大值的位置。分析了由激励层和抑制层组成的场。除了稳定的局域激发外，场还具有诸如产生振荡波、行波、活跃的和双活跃的瞬变等模式动力学。
The dynamics of pattern formation was studied for lateral-inhibition type homogeneous neural fields with general connections. Neural fields consisting of a single layer were treated, and it was proved that there are 5 types of pattern dynamics. The type of the dynamics of a field depended not only on the mutual connections within the field but on the level of homogeneous stimulus given to the field. An example of the dynamics is as follows: a fixed size of localized excitation, once evoked by stimulation, can be retained in the field persistently even after the stimulation vanishes. It moves until it finds the position of the maximum of the input stimulus. Fields consisting of an excitatory and an inhibitory layer were analyzed. In addition to stationary localized excitation, fields have such pattern dynamics as production of oscillatory waves, traveling waves, active and dual active transients, etc.
