Abstract : How does the connectivity of a neuronal circuit, together with the
individual properties of the cell types that take part in it, result in
a given computation? We examine this question in the context of retinal
circuits. We suggest that the retina can be viewed as a parallel
assemblage of many small computational devices, highly stereotypical and
task-specific circuits afferent to a given ganglion cell type, and we
discuss some rules that govern computation in these devices.
Multi-device processing in retina poses conceptual problems when it is
contrasted with cortical processing. We lay out open questions both on
processing in retinal circuits and on implications for cortical
processing of retinal inputs.
