Example set of linked EPSC/IPSCs recorded from a single pallidal neuron. They have been aligned horizontally at the onset of the EPSC, and vertically at the baseline current before EPSC onset. The latency to positive current (emergence of the IPSC) was measured for over 100 linked events in each of nine neurons. The mean latency was 2.29 ± 0.36 ms (n = 9 neurons); the SD of that latency was 0.74 ± 0.16 ms. We consider these values, in particular the SD of the latency, to be much higher than expected for a simple corelease mechanism underlying the linked events.
