Well, some of the components of the visual pathway operate in analog mode.
For example, no spiking is observed in the retina before the ganglion
cells. How do you proposed to measure the bandwidth between two systems
that communicate via graded potentials (i.e., electrical synapses)? There
is moderately similar behavior in some places in the pathway from area V1
to RH. Trying to measure the bandwidth of this pathway is a hard problem.
