(PsyPost) – A new study reveals the human brain’s remarkable ability to maintain communication between its two hemispheres even when the primary connection is almost entirely severed.
Researchers discovered that a tiny fraction of remaining nerve fibers is sufficient to sustain near-normal levels of integrated brain function, a finding published in the Proceedings of the National Academy of Sciences. This observation challenges long-held ideas about how the brain is wired and suggests an immense potential for reorganization after injury.
The brain’s left and right hemispheres are linked by the corpus callosum, a massive bundle of about 200 million nerve fibers that acts as a superhighway for information. CONTINUE
