In a paper at Nature Neuroscience, researchers reported on human vs. macaque brains on input/output systems and synergy between regions:
Our brain regions for sensory and motor functions use a simple input/output system with high reliability due to high redundancy (repetition). Our eyes duplicate most of each other’s information but that helps ensure that our view of the scene is correct. However, there is a very different way of processing information — synergistic processing — which integrates signals from across a variety of brain networks. This approach is better adapted, the researchers say, to “attention, learning, working memory, social and numerical cognition.” Unlike the visual system, it is not hardwired. It adapts readily to changing circumstances, connecting different networks in different ways at different times.

Takehome: The researchers found that, from an information theory perspective, human brains engage in less redundant and more synergistic processing than macaques. So information theory supports human exceptionalism where Darwinism doesn’t?

A pair of researchers have introduced an Information Continuum Model of Evolution (ICM) which takes into account that information is immaterial. The paper is open access.
