This research study investigates how learning a task transforms the way neurons in the macaque visual cortex process and share information. Contrary to the classic belief that the brain improves efficiency by reducing overlapping signals, the authors discovered that information redundancy actually increases as animals become more proficient at a task. By recording neural activity over several weeks, they observed that neurons began to share more task-relevant data through feedback and internal inference rather than operating as independent sensors. This shift suggests that sensory processing…
