Unformatted text preview: Innervation of the Inner Ear is regulated by BDNF and NT3-double mutants – inner ear = uninnervated -BDNF in NT3 region = cochlear becomes innervated by vestibular part of ganglion Secondary Targets: Visual and Auditory Targets Share Similar Cues-EphrinA2/EphrinA5 define the border between LGN and MGN Target Specific Regeneration-SCG = superior cervical ganglion -Different SCG secret specific signals to attract T1 or T4 to reinnervate the right target even after you cut it SCG and T5 are targets of anterior and posterior spinal roots Transplant T5 into SCG and the more posterior roots innervate T5 (specificity between axon and their target) Sema III is expressed in VENTRAL SPINAL CORD and it REPELS axons of CGRP (calcitonin gene related peptide) neurons Maladptation-tectum = eye-page 2 FROG eye CUTTING experiment! -...
