title: [Qualitative and quantitative investigations of the area striata in an ontogenic series of male Tupaia belangeri].
abstract: The cyto-, myelo- and fibrilloarchitectonics of the area striata and its laminae were described in 36 male Tupaia belangeri at an age of 36 to 536 days of ontogenesis. The fresh volumes of the area striata and its laminae were determined and the growth of the fresh volumes described with the 6-parametric growth-function: (formula: see text) Likewise, the matter lying directly under the area striata were determined and these data were analysed with the logistic growth-function: (formula: see text) 1) During ontogenesis, the area striata and its laminae show a growth over-shoot of the fresh volumes with differing procentual reduction, which is greatest (45%) at lamina IIIc and the least (18%) at lamina VI. The points in time for maximal fresh volume and the reduction speeds are different. Initially, the reduction of lamina VI is finished and that of lamina I, lastly. 2) The associated white matter of the area striata shows a nonlinear a monotonous increase in fresh volumes.
