We have studied the cortical diffusion characteristics of seizures induced at cornu Ammonis with mechanical stimulation. We have observed that cerebral cortex syncronizes with cornu Ammonis showing a similar morphology. The cortical diffusion is iniciated at the homolateral occipital area. The focal paroxismal activity of one of the cornu Ammonis can be spread to the contralateral homologous area, being then cornu Ammonis the responsible structure for the bilateral cortical diffusion. Nonetheless it has been observed that being the paroxismal activity localized at one of the cornu Ammonis formation the cortical activity is spread to both hemispheres. We must consider in this case that the bilateral cortical diffusion is originated in an intermediate structure between cornu Ammonis and cerebral cortex. Very often the corical paroxismal diffusion is simultaneous with recruiting phases. (hese and some other considerations induce as to think that the cyngulus might be an important structure for the bilateral cortical diffusion of focal paroxismal activity localized an one of the cornu Ammonis.
我们研究了通过机械刺激在海马角诱发的癫痫发作的皮质扩散特征。我们观察到大脑皮质与海马角同步，呈现出相似的形态。皮质扩散始于同侧枕叶区域。一个海马角的局灶性发作活动可扩散至对侧同源区域，因此海马角是双侧皮质扩散的责任结构。然而，已经观察到，当发作活动局限于一个海马角结构时，皮质活动会扩散到两个半球。在这种情况下，我们必须考虑双侧皮质扩散起源于海马角和大脑皮质之间的一个中间结构。皮质发作性扩散常常与募集期同时发生。（这些以及其他一些考虑因素促使我们认为，扣带回可能是局限于一个海马角的局灶性发作活动双侧皮质扩散的一个重要结构。 （原文中“(hese”应为“These”；“cyngulus”应为“cingulate gyrus”，翻译中已修正）
