Thought this might be of interest on this list: "Release of neurotransmitter is an inherently random process, which could degrade the reliability of postsynaptic spiking, even at relatively large synapses. This is particularly important at auditory synapses, where the rate and precise timing of spikes carry information about sounds." http://www.ncbi.nlm.nih.gov/pubmed/24005293
It suggests that the phenomenon that introducing dither noise into an audio signal can improve intelligibility of low amplitude signals (pushing enough samples above the noise floor that the brain will fill in the blanks) is also inherently present in the brain. -Tim -- http://timboudreau.com
