When the eyes play tricks, the brain builds consensus
Medical Xpress • • general
Key Points:
- Researchers from Cold Spring Harbor Laboratory, University of Cambridge, and University College London studied how two neighboring visual cortex regions, V1 and LM, interact to resolve conflicting visual information.
- Their experiments with mice showed that when these regions agreed on visual input, their shared neural activity lasted longer, but mismatched activity patterns quickly faded within fractions of a second.
- This process, termed "consensus building," reveals how the brain forms unified perceptions despite specialized, distinct sensory inputs in different areas.
- The team is investigating whether similar consensus mechanisms operate across the entire neocortex, potentially explaining how the brain reconciles conflicting sensory information beyond vision.
- Understanding this dynamic consensus may improve knowledge of brain function and inspire artificial intelligence systems that better handle conflicting data.
