behavior/neurological
• when lifted by tail, homozygotes flex the hind limbs, in contrast to wild-type which extend legs
• compared to wild-type mice, mutants are 90 times more likely to fall off of a rotating rod in a rotarod test; (J:100972)

muscle

nervous system
• in 3 month old mice, dilated axons are detected in the spinal cord and cerebral cortex, although numbers are fewer than in Tg(Thy1-MAPT)1Vln homozygotes
• cytoskeletons of dilated axons are disrupted, with numerous randomly oriented microtubules engirdling accumulations of pleomorphic vesicles, dense-cored vesicles, and smooth endoplasmic reticulum; ratio of microtubules to neurofilaments in dilated axons is high relative to normal axons
• grouping of atrophic fibers and fascicular atrophy are observed
