Hypokinetic stress and neuronal porosome complex in the rat brain: The electron microscopic study

► Hypokinetic stress alters structure of presynaptic area in amygdalar central nucleus. ► Hypokinetic stress doesn't alter depth and diameter of porosome in this nucleus. ► Parameters of porosome are heterogenous in normal and stress-induced rats. ► Dimensions' fluctuation of porosome complex in normal and stressed rats are the same.
