Characteristics of primate neuronal face code

Proceedings of the National Academy of Sciences

Extending a previous study that predicted human facial identity from the firing rates of a population of around 100 neurons in a region of the brain of awake monkeys, a study finds that neurons in the brain's anterior medial patch, implicated in face recognition, use a rule, called a "combinatorial code," to adjust firing rates of individual neurons such that the average firing rate for the population of neurons remains the same for each of 2,000 faces; further, the fruit fly olfactory system uses the same combinatorial code to identify odors, according to the author.
