nervous system

nervous system phenotype ( J:41127 )

N • homozygous mutant mice were behaviorally normal and displayed no major differences in any structure of the brain, including the brainstem and cerebellum, relative to wild-type

abnormal axon guidance ( J:41127 )

• retrograde labeling experiments revealed a commissural defect, whereby tectal axons failed to project from the superior colliculus of the midbrain to the contralateral inferior colliculus

abnormal nervous system tract morphology ( J:41127 )

• notably, homozygous mutant mice exhibited an aberrant ipsilateral axonal tract that projected to the ventral region of the cervical spinal cord

• retrograde labeling revealed that these abnormal projections originated from a small subpopulation of superior colliculus neurons
