p075fig02.24 The membrane equations of neurophysiology describe how cell voltages change in response to excitatory, inhibitory, and passive input channels. Each channel is described by a potential difference multiplied by a conductance. With the special choices shown in the lower right-hand corner, this equation defines a feedforward shuntin on-center off-surround network.

V | Voltage |
V(+), V(-), V(p) | Saturating voltages |
g(+), g(-), g(p) | Conductances |
