WebAre postsynaptic potentials (PSPs) visible? These could be excitatory (EPSPs), inhibitory (IPSPs), or EPSPs leading to spikes. Depending on the activity level, measure the following properties. Use Figure 8.7, Action Potential Measurements as a guide when making the following measurements. Silent Cells Record the resting potential. WebStimuli were single delivered at 0.033 Hz via an isolated pulse stimulator (model 2100; AM System Inc, Billerica, MA, USA), and stimulation intensity (0.1 ms, 50–200 μA) was adjusted to produce evoked excitatory postsynaptic current (eEPSC) or evoked inhibitory postsynaptic current (eIPSC) amplitudes that were 60%–70% the maximal responses in …
