脑保存技术取得巨大飞跃

Neuroscience Huge leap for brain preservation A pig’s brain has been frozen with its cellular activity locked in place, with minimal damage. Some think the same could be done with the brains of people, finds Helen Thomson AN ENTIRE mammalian brain has been successfully preserved using a technique that will now be offered to people who are terminally ill. The intention is to preserve all the neural information thought necessary to one day reconstruct the mind of the person it once belonged to. “The approach is essentially a form of fixation using toxic chemicals that preserves the structure of the brain and neurons, but without expectation of biological viability,” says Joao Pedro de Magalhaes at the University of Birmingham, UK. …
