Abstract

Late spreading of excitation occurs in the lateral geniculate nucleus following partial retinal lesions. The extent of spreading remained the same when reducing the size of the lesions to one fifth. This is incompatible with the idea that the spreading could be caused by displacement of normal cells into the deafferented area as a consequence of transneuronal volume reduction.

摘要

在部分视网膜损伤后，外侧膝状核中会出现兴奋的晚期扩散。当将损伤大小减小到五分之一时，扩散程度保持不变。这与以下观点不相符，即这种扩散可能是由于跨神经元体积减小导致正常细胞移位到去传入区域所引起的。
