MINIMAL EMBEDDING DIMENSIONS OF CONNECTED NEURAL CODES.

A receptive field code is a recently proposed deterministic model of neural activity patterns in response to stimuli. The main question is to characterize the set of realizable codes, and their minimal embedding dimensions with respect to a given family of receptive fields. Here we answer both of these questions when the receptive fields are connected. In particular, we show that all connected codes are realizable in dimension at most three. To our knowledge, this is the first family of receptive field codes for which both the exact characterization and minimal embedding dimension are known. [ABSTRACT FROM AUTHOR]
