Average (±SE) values and statistical comparisons of inhibitory postsynaptic currents (IPSCs) by cell type and mouse line. Note that no values are given for amplitude or decay for Purkinje cells from KO animals, and one cell was excluded from PC-Mixed-HEMI decay analysis, due to too few IPSCs. HEMI, hemizygous; KO, knockout; MW, Mann–Whitney tests; PC, Purkinje cell; WT, wild-type.
