behavior/neurological
• at low doses (1 mg/kg) diazepam does not induce a sedative effect in homozygous mutants, however at high doses (3.2 mg/kg) a sedative effect is seen in mutants and wild-type mice
|
• mutants fall more often and earlier in a rotarod test
|
nervous system
• Zn2+ fails to inhibit and diazepam fails to potentiate GABAA receptor-mediated Cl- currents in mutant hippocampal neurons unlike in wild-type
