The neurophysiology of magnitude: One example of extraction analogies.

Abstract Brain mapping for analogical information seems based on extraction of similarity on various levels, including perceptual similarity, abstract conceptual dimensions, and goals. Given the utility of analogical inferences on quantities that would extract covariance of time, space, and numbers, we discuss here the processing of time, space, and quantity as an example of the process of extraction of analogical information. This view is supported by evidence documenting common activation of the prefrontal cortex (PFC) in the processing of all of these magnitudes.
