Websought to describe the role of temporal coding in olfaction. Hopfield model: latency coding. Hopfield (1995) proposed a theoretical model for pattern recognition. The model assumes common oscillatory inputs to a population of neurons. When these neurons receive different levels of constant input, those receiving stronger input fire early

The transduction mechanism for olfaction … 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.
