golgi studies on the cerebral cortex ( central region ) of newborn and adult bats ( myotis myotis ) have shown that ( a ) extraverted cells in layer ii-iii are the source of a rich horizontal plexus originating from large numbers of long , proximal axonic collaterals , and ( b ) significantly greater numbers of basilar and apical dendrites ( student 's t-test , p less than 0.001 ) of extraverted pyramidal cells are found in the newborn than in the adult bat , indicating an overproduction of dendrites during the early stages of development .
