科学家通过脑机接口恢复失明动物视觉功能

2025-06-06 16:43 by 时间的折皱

复旦大学等团队在《科学》上报告,借助脑机接口等技术,新一代视觉假体不仅使失明动物恢复可见光视力,还可扩展其视觉功能,这为失明患者复明提供了新可能。研究显示,该团队开发出全球首款光谱覆盖范围极广(470-1550nm,从可见光延伸至近红外二区)的视觉假体,该假体无需依赖任何外部设备,即可使失明动物模型恢复可见光视觉能力,还能赋予动物感知红外光,甚至识别红外图案的“超视觉”功能,也就是在黑暗中也能看见事物。在非人灵长类动物(食蟹猴)模型上的实验验证了该假体的有效性。植入半年后,动物模型均未观察到任何不良排异反应,这为后续推进临床应用转化奠定了重要基础。考虑到目前医学伦理的限制,研究暂时不会进入临床试验阶段。

Look for Channels Online

You guessed it – the internet is your friend. A good place to start looking for Telegram channels is Reddit. This is one of the biggest sites on the internet, with millions of communities, including those from Telegram.Then, you can search one of the many dedicated websites for Telegram channel searching. One of them is telegram-group.com. This website has many categories and a really simple user interface. Another great site is telegram channels.me. It has even more channels than the previous one, and an even better user experience.These are just some of the many available websites. You can look them up online if you’re not satisfied with these two. All of these sites list only public channels. If you want to join a private channel, you’ll have to ask one of its members to invite you.
