mortality/aging
|

|
growth/size/body
|
• mice have slightly reduced body weight compared to single or double knockout littermates
|
nervous system
|
• ratio of glutamatergic vs GABAergic/glycinergic terminals is reduced in the PBC and inferior olive in mutants, but not in hypoglossal neurons
• there is a 30% reduction in number of postsynaptic clusters containing GABAAR alpha 1in the PBC
|
|
• spontaneous postsynaptic currents from Pre-Botzinger complex (PBC) neurons are reduced in frequency and duration compared to single knockout animals
• number of GABAergic and glycinergic sPSCs with lower and higher amplitudes are decreased by 85% and 95% respectively
• frequency of GABAergic and glycinergic miniature PSCs (mPSCs) in PBC neurons is reduced by 80% compared to single knockout controls cells
• frequency of spontaneous glutamatergic postsynaptic currents is decreased compared to single null PBC neurons
• amplitudes of GABAergic/glycinergic evoked postsynaptic currents (ePSCs) are strongly decreased compared to single knockout neurons, while amplitudes in double knockout neurons is not significantly changed

respiratory system
|
• mice show irregular and flat breathing movements
