behavior/neurological
N |
• no overt behavioral abnormalities, including reflexes, anxiety related behaviors, sensorimotor responses, fear conditioning and exploratory activity
|
• motor learning performance is impaired on the accelerating rotarod test; mutant mice perform similarly to controls in the first two training sessions, but do not improve from trial 2 to 3 as do control mice
• mutant mice perform similar to controls in coordination, strength and balance tests such as vertical pole and hanging wire test
|
homeostasis/metabolism
N |
• T4 plasma levels are similar to controls
• plasma glucose levels are similar to controls
|
• plasma corticosterone levels are significantly elevated compared to controls
|
• plasma growth hormone levels are 3 times greater than controls
but body weight is normal
|
nervous system
N |
• no gross abnormalities of brain morphology, including the characteristic layering of cells in the cerebellar cortex
