Pax7 and superior collicular polarity: insights from Pax6 (Sey) mutant mice.

abstract：:The time of maximal occurrence of pyknotic nuclei in the retinal ganglion cell layer of postnatal pearl mutant mice is earlier than that in normal mice (Linden and Pinto 1985). Both ganglion and displaced amacrine cells and glia populate the ganglion cell layer. Thus, in order to show that ganglion cells themselves ar...

abstract：:To explore visual space, we make saccades, vergence, and, most frequently, combined saccade-vergence eye movements. The initiation of saccades is well studied, while that of vergence is less explored. Saccade latency is influenced by the fixation task: when the target appears simultaneously with the offset of the fixa...
