At thelevel of the recess the fibers of the acoustic nerve reach the dorsal edge of thealar lamina, which, accordingly, undergoes development at this point intovestibular and cochlear nuclei. More rostrally it undergoes an excessive devel- 195 ig6 THE NERVOUS SYSTEM opment, which is stimulated by the growth into it of afferent fibers from thevestibular nerve and of sensory fibers of the second order, bringing afferentimpulses from other sources, chiefly from the somatic musculature. Thispart of the alar lamina, which may be regarded as an overgrown portion of thevestibular nucleus, develops into the cerebellum. As the pai
