摘要：
The normal development of the superior collicular map of auditory space in the guinea pig requires visual experience (Eur. J. Neurosci., 2 (1990) 682-692). The possible role of the visual cortex in this process was assessed by unilateral removal of the cortex prior to the crucial period during which visual experience is needed (Neurosci. Lett., 116 (190) 280-286). This removal did not affect the normal emergence of an ordered auditory space map in the superior colliculus. The cortico-tectal pathway does not appear, therefore, to play an essential role in the development dependence of the collicular auditory map upon visual experience.
