Excitation and inhibition are balanced in the Hamiltonian network.

<p><b>A.</b> Trial-average excitatory input vs. trial-average inhibitory input across trials (dots) for a randomly selected individual cell in the network. <b>B.</b> Total inhibitory input to a single cell (blue) closely tracks but slightly lags total excitatory input (red) over the course of a trial. <b>C.</b> The cross-correlation between the average excitatory and average inhibitory membrane potentials shows a peak that is offset from 0 time.
