nervous system
• 35 of 37 neurons display dysmorphic axons compared to only 5 of 40 wild-type axons in cortex in 6-month old mice
• at 1 year of age, an increase in degenerating neurons, including pyramidal neurons, is seen in the cortex compared to wild-type mice
• the density of GFAP+ cells is increased 9-fold and 6-fold in the cortex and striatum, respectively, compared to wild-type littermates at 6 months
• at 1 year of age, an increase in degenerating neurons, including pyramidal neurons, is seen in the cortex compared to wild-type mice
• spontaneous inhibitory postsynaptic current frequency but not amplitude is significantly decreased; however no change in spontaneous excitatory postsynaptic currents is seen

behavior/neurological
• activity is reduced at 6, 8, and 10 months of age but not at 2 months of age
