Abstract

During continuous movement of a large global pattern remote from the classical receptive field retinal ganglion cells discharge considerably faster (continuous shift effect), and center responses are decreased in amplitude for neurons with a relatively high ongoing activity (mostly ON-center) but increased for neurons with no ongoing discharge (mostly OFF-center). The results suggest that all retinal ganglion cells have more or less access to one long range mechanism, which is non-linear and almost all-or-none in nature.

摘要

在远离经典感受野的大尺度全局模式持续移动期间，视网膜神经节细胞放电速度显著加快（连续移位效应），对于具有相对较高持续活动的神经元（大多为ON中心型），其中心反应的幅度减小，而对于无持续放电的神经元（大多为OFF中心型），其中心反应的幅度增大。结果表明，所有视网膜神经节细胞或多或少都能利用一种远距离机制，这种机制本质上是非线性的，几乎是全或无的。
