Debunking the Myth of Brain Rewiring: New Study Challenges Prevailing Beliefs

Contrary to popular belief, a new study argues that the brain does not have the ability to rewire itself in response to injury or deficit. Scientists from the University of Cambridge and Johns Hopkins University challenge the notion that the brain can repurpose specific regions for new functions, suggesting instead that it is simply training the brain to use latent abilities. The study examines 10 seminal studies that purportedly show brain reorganization and argues that the brain is not creating new functions but rather using existing capacities. The researchers emphasize the importance of understanding the true nature and limits of brain plasticity for setting realistic expectations in rehabilitation.

Unveiling the Unexpected Flexibility of Adult Vision

Researchers have discovered that the adult mammalian brain retains a high degree of plasticity, challenging the belief that it becomes rigid after a critical developmental period. Using a novel setup involving rodent MRI scanners, the study found that when rodents deprived of light from birth were exposed to light in adulthood, their brains underwent significant reorganization and adaptation. This suggests that the adult brain can process new visual signals, opening up new possibilities for visual rehabilitation treatments in adults. The findings also have potential implications for predicting treatment responses in patients and understanding disease progression in animal models.
