Comparative morphology, cytochemistry and innervation of chromaffin tissue in vertebrates.

abstract：:The developing human brain can compensate for pre- and perinatally acquired focal lesions more effectively than the adult brain. The mechanisms by which this effective reorganization is achieved vary considerably between different functional systems, reflecting differences in the normal maturation of these systems. In...
