For each type of neural connection between E, L, and C cells, an \(H_{c}\) function is computed to represent the effects of neurons on the voltage of the neuron within the oscillator. The six \(H_{c}\) functions are computed for connections from L to E cells, C to E cells, C to L cells, E to C cells, L to C cells, and C to C cells. Here we show only half of the neuron-to-neuron connections in Fig. 1 because of the left–right symmetry within the oscillator
