WebJun 18, 2012 · The “efficient-coding hypothesis” has been explored by Kostal et al. focusing on intensity coding with the use of information theory techniques. However, the analysis of quality coding, i.e. the early olfactory system’s ability to detect and discriminate different odors, in an information theory framework has received less attention. http://charlesfrye.github.io/FoundationalNeuroscience/49/
