The properties of EIN-evoked EPSPs. Histograms of EPSP amplitudes (A), rise times (B), and half-widths (C) are shown. Di,Dii, An example of an electrical connection between an EIN and a motor neuron. Notice that the chemical component varies, but the electrical component is constant. The chemical but not electrical component was blocked by cadmium (200 μm).E, An example of a connection in which EIN stimulation at 20 Hz consistently evoked spikes in the postsynaptic motor neuron.F, The relationship of the coefficient of variation to the initial EPSP amplitude. Each symbol represents a single connection.
