Binocular 3D otolith-ocular reflexes: responses of normal chinchillas to tilt and translation.

abstract：:1. Intracellular and extracellular recordings were obtained from ganglion cells in the rabbit retina. The effect of N-methyl-DL-aspartate (NMDLA) and N-methyl-D-aspartate (NMDA) antagonists were studied with the use of a perfusion method for drug application. 2. NMDLA excited all ganglion cell types and caused a chara...
