)
• over time excessive grooming results in ulcerations with hemorrhage
|
behavior/neurological
N |
• no difference in gross motor skills and no impairment in motor learning
|
• chronic administration fluoxetine leads to a significant reduction in the duration of grooming
|
• mice show a lower percentage of time spent in the center compartment and a lower number of entries into the center compartment in the open-field test
• reduced time spent in open arms in the elevated-plus-maze test
• increase in marble-burying behavior
|
• a significant increase in the duration of grooming events compared to wild-type
• chronic administration fluoxetine leads to a significant reduction in the duration of grooming
|
nervous system
• volume of striatum is significantly reduced compared to wild-type mice
|
• significant decrease in dendritic complexity of striatal neurons
• a decrease in dendritic arbor complexity at distances greater or equal to 50 um from the soma
|
• a significantly reduced population spike amplitude as a measure of defects in corticostriatal neurotransmission
