New Framework Reveals How the Brain Compresses a Noisy World into Coherent Perception
A new framework published in Quanta Magazine describes how the brain compresses a torrent of noisy sensory signals—from photons hitting the retina to molecules binding in the nose—into a stable, coherent perception of the world. The model, developed by theoretical neuroscientists, suggests that the brain uses a hierarchical predictive coding system that actively filters out noise while preserving critical information, offering a potential unifying principle for sensory processing across modalities.
