Abstract

Visual wulst responses to ipsi- and contralateral visual stimuli were investigated in young zebra finches (Taeniopygia guttata castanotis Gould) of different ages. Contralateral responses in 20, 40, 60 and 80 day old birds do not differ significantly from those in adults. In contrast, ipsilateral responses decrease substantially during development and become very weak and irregular in adult birds.

摘要

在不同年龄的幼年斑胸草雀（Taeniopygia guttata castanotis Gould）中，研究了视叶对同侧和对侧视觉刺激的反应。20日龄、40日龄、60日龄和80日龄鸟类的对侧反应与成年鸟类的对侧反应没有显著差异。相比之下，同侧反应在发育过程中大幅下降，在成年鸟类中变得非常微弱且不规则。
