Their calculations award higher scores to information-rich responses: those that are distributed across the brain, but also individualized. If two distant groups of neurons are active, but their activity is synchronized, the PCI equation compresses them, meaning they contribute less to the overall score. “The less we can compress the pattern, the more information is in it,” Massimini explains.
