Development of the Optic Tectum in Brown Trout

  • S. C. Sharma
Part of the NATO Advanced Study Institutes Series book series (NSSA, volume 1)


The complexity of cellular characteristics and their interrelationships in the teleostean optic tectum is quite apparent from Dr. Venegas’review (this volume). In order to accomplish the early events of neurogenesis, certain morphological and cellular changes occur in the presumptive optic tectum and these changes probably cause the transformation of the “matrix zone” (proliferative ventricular cells) into post-mitotic neurons.
