nervous system
• white matter subjacent to the internal granule layer and the molecular layers is disorganized
|
• observed in white matter by electron microscopy
|
• redundant myelin sheaths
• myelin vacuolization
|
• filled with mitochondria and other organelles
|
• initial myelinogenesis is normal
• myelin structure has a shorter periodicity than for controls
|
demyelination
(
J:62287
)
• widespread demyelination as mice age
|
behavior/neurological
• rotarod performance deteriorates as demyelination progresses
• mice perform well on a rotarod until about 1 year of age after which performance declines
