Dynamics in dynamically balanced trained spiking networks.
A: Input currents onto a neuron in a spiking network trained to produce a superposition of 4 sine waves as in Fig 2A. Red curve: total excitatory current hE + IE; Blue curve: inhibitory synaptic current hI; black curve: total current h. B: Voltage traces of 5 sample units the network with random fast synaptic currents (time constant 2 ms). C: Spike raster of 200 neurons for the network in B. D: Histogram of the coefficient of variation of interspike intervals across neurons for the network in B.
