Abstract

The ferret retinogeniculate projection is organized into on/off sublaminae within each eye-specific layer. The role of afferent activity in the formation of these sublaminae was examined. We report that when the activity of retinal ganglion cells is blocked with tetrodotoxin during postnatal weeks three and four, on/off sublamination is disrupted, supporting a role for afferent activity in the formation of this pattern.

摘要

雪貂的视网膜-膝状体投射在每个眼特异性层内被组织成开/关亚层。研究了传入活动在这些亚层形成中的作用。我们报告,在出生后第三和第四周用河豚毒素阻断视网膜神经节细胞的活动时,开/关分层被破坏,这支持了传入活动在这种模式形成中的作用。
