N normal phenotype
behavior/neurological
• mice spend more time in the inner regions of an open field compared with wild-type mice
• some mice exhibit spastic head movements unlike wild-type mice
• beginning at 2 to 3 months of age
• when lowered onto a horizontal pen, mice fail to walk along it and fall with severely affected mice unable to sit on the pen unlike wild-type mice
• mice exhibit impaired performance on a rotarod compared with mice containing only one of the transgenes
• however, mice treated with doxycycline exhibit improved rotarod performance
• in an open field test, especially in inner areas

nervous system
• in some neuronal cells of the cerebral cortex by 1 month old mice
