Knowledge of the bioelectric signal-to-noise ratios in rat brain makes it possible to demonstrate for the first time that the brain functions as a coherent signal detector, an important class of detectors that are explicitly formulated within the statistical theory of communication. Within an afferent neuronal channel of a single modality, the brain functions as a parallel signal processor.
