Differences in threshold and latency of EPSPs evoked by graded DR stimulation in pairs of synaptically connected PrP-GFP and islet neurones A, reciprocally connected PrP-GFP and islet cells. B, unidirectional connection from PrP-GFP to an islet cell. C, unidirectional connection from islet to PrP-GFP cell. Note that the threshold and latency show a consistent difference for the two cells in each connection pattern. All resting membrane potentials were −60 mV.
