behavior/neurological
• mice show mildly increased anxiety-like behavior in the light-dark test
• however, mice show normal behavior in the elevated plus maze and in the center region of the open-field arena
|
• mice show impaired motor coordination in the Erasmus ladder test
• however, mice do not show any abnormalities in social interaction, social novelty recognition, ultrasonic vocalization, repetitive behaviors (self-grooming, jumping, digging, and marble burying), in the rotarod test, and open-field behavior and show normal visual and olfactory function
|
• mice show increased repetitive behavior in the hole-board test
|
nervous system
• reduction in levels of excitatory synaptic protein (GluD2 and PSD-93) levels in the cerebellum
|
• Purkinje cells show miniature excitatory postsynaptic currents (mEPSCs) with reduced frequency but normal amplitude
• however, mice show normal LTD at parallel fibers-Purkinje cell synapses in the cerebellum
