A method to measure the precise relationship between neuronal firing rates and the representation of accumulated evidence is described; results in the parietal and prefrontal cortex of rats, together with transient optogenetic inactivation of the prefrontal cortex, challenge the prevailing view that the prefrontal cortex is part of the neural circuit for accumulating evidence, and suggest that neurons in parietal and prefrontal areas have distinct relationships to evidence accumulation in decision-making.
