肠道微生物影响大脑可塑性

Climate change Seaweed for CO₂ removal may backfire Microbiome influences brain plasticity Alec Luhn Chris Simms A FAECAL microbiome transplant (FMT) could make an older brain as adaptable as a young one. For the first time, a study has shown that older mice given the gut microbiomes of younger ones via an FMT experience improved brain plasticity. Neuroplasticity, the brain’s ability to remodel itself, peaks at a young age, decreasing as our brains naturally prune unused connections during adolescence. This means that certain conditions like amblyopia, also known as lazy eye, are typically only successfully treated in childhood. This is done by covering the stronger eye, forcing the brain to forge new connections to the weaker eye. …
