  1. Miniature endplate potentials (MEPPs) are recorded from five to six NMJs of the left diaphragm of each of three Fgf18+/+ and three Fgf18−/− mice at E18.5. Relative areas of the fifth and first compound muscle action potentials (CMAPs) at the 2-Hz stimulation of the sciatic nerve in five Fgf18+/+ and three Fgf18−/− are indicated. Mean and standard error of mean are indicated. Statistical significance (p) is calculated with the Student’s t-test.
