[Qualitative and quantitative studies on the lateral geniculate body in an ontogenic series of male Tupaia belangeri].
The cyto-, fibrillo- and myeloarchitectonics of the dorsal and ventral lateral geniculate body are described in an ontogenetic series of male Tupaia belangeri using light microscopy. The qualitative maturational changes show a heterochronical development. The ventral nucleus is developing earlier than the dorsal nucleus. A quantitative analysis of the fresh volume growth of the two brain regions also shows a heterochronical development. Two different kinds of growth curves were found. The dorsal lateral geniculate body has an overshooting growth which is approximated by the 6-parametric growth function: formula: (see text), The ventral lateral geniculate body shows a monotonously increasing s-shaped growth curve which is approximated by the generalized logistic growth function: formula: (see text), An analysis of the fresh volume growth of the six layers of the dorsal lateral geniculate body demonstrates all layers to take part in the overshooting growth type.
