Abstract
1. The rapid and transient redistribution of Ca2+ from intracellular membrane-bound compartments (stores) is a key event of cell activation. 2. The cytological nature and molecular composition of such Ca2+ stores have been the object of intense investigation in recent years. 3. Here we review: (a) the current knowledge on intracellular Ca2+ stores of Purkinje neurons at the functional, biochemical, molecular, morphological and ultrastructural level; and discuss: (b) the relationship between Ca2+ stores and the endoplasmic reticulum, and (c) the occurrence of multiple/heterogeneous Ca2+ stores.
