A: Six overlapping consecutive traces of sEPSCs (left) and sIPSCs (right) in DMV neurons voltage clamped at −60mV and −50mV, respectively. Ghrelin (100nM) was applied by superfusion for at least 3 minutes, or until the response reached plateau. Note that ghrelin increased the frequency of sEPSCs in a reversible manner, whereas ghrelin had no effect on sIPSC frequency.
B: computer generated graphics from the same neuron in A (left) showing the ghrelin-induced alteration in sEPSC frequency (left) but not amplitude (right).
C: Graphical summary of the effects of ghrelin to increase sEPSC frequency but not amplitude
