Histological serial sections, three-dimensional reconstructions and morphometry served to study the postnatal development of V1 in tree shrews. The main objectives were to evaluate the expansion of V1, the implications of its growth on the occipital cortex and, vice versa, the effects of the expanding neocortex on the topography of V1. The future V1 was identified on postnatal day 1 by its...

Deficiency in parvalbumin, but not in calbindin D-28k upregulates mitochondrial volume and decreases smooth endoplasmic reticulum surface selectively in a peripheral, subplasmalemmal region in the soma of Purkinje cells

The Ca²⁺-binding proteins parvalbumin (PV) and calbindin D-28k (CB) are key players in the intracellular Ca²⁺-buffering in specific cells including neurons and have profound effects on spatiotemporal aspects of Ca²⁺ transients. The previously observed increase in mitochondrial volume density in fast-twitch muscle of PV−/− mice is viewed as a specific compensation mechanism to...
