Relative changes of FP amplitudes in WT and M₂/M₄ mAChR KO mice following bath application of different ACh concentrations

ACh	20 μm	100 μm	500 μm	1.5 mm
Control (WT)	111 ± 4% (6)	117 ± 2% (8)	120 ± 2% (5)	87 ± 5% (6)
M2/M4 KO	98 ± 4% (6)	102 ± 5% (6)	100 ± 3% (6)	86 ± 6% (8)

Values of n are given in parentheses. Each value represents the mean amplitude of FPs ± s.e.m. during the last 3 min of ACh application normalized with respect to the mean amplitude of FPs during the last 3 min of baseline.
