DPKQDFMRFamide enhances synaptic transmission at the larval neuromuscular junction. Excitatory junctional currents (EJCs) were evoked in muscle fiber 6 by electrical stimulation of the abdominal nerve. Representative EJCs (preceded by the stimulus artifact) are shown above. The mean EJC amplitude ± SEM as a function of time after the application of 100 nm DPKQDFMRFamide is plotted below(n = 4–6 at each point). *p < 0.05 (Student’s t test, compared with the baseline mean). Calibration: 20 nA, 20 msec.
