新型大脑芯片:拥有超人的记忆力不再是梦想

2016-10-29 MedSci MedSci原创

向人脑中植入大脑芯片、让人类拥有超人的记忆力,这听上去好似科幻片中的情节。但一名富有开创精神的神经科学家已经准备开始在人类身上尝试这一未来科技了。 为了将短期记忆转化为长期记忆,大脑会将电信号以一种特殊的编码形式释放出去。而这种大脑芯片释放的电信号与大脑产生的信号相符,模拟了产生长期记忆的自然过程。向人脑中植入大脑芯片、让人类拥有超人的记忆力,这听上去好似科幻片中的情节。但富有开创精神的神经科学

该芯片的设计者为南加州大学的生物医药工程教授西奥多·伯尔格博士(Dr Theodore Berger)。在过去的20年间,他一直在研发各式各样的大脑假体(能够模拟大脑电信号的植入物),以此研究阿尔茨海默症。该软件可以将短期记忆转化为长期记忆,因此能改善整体记忆力。

为了将短期记忆转化为长期记忆,大脑会将电信号以一种特殊的编码形式释放出去。而这种大脑芯片释放的电信号与大脑产生的信号相符,模拟了产生长期记忆的自然过程。目前,科学家已经在猴子和小鼠身上测试了这种芯片,两种动物的记忆力均有提高。

伯尔格博士目前正与科技企业家布莱恩·约翰逊(Bryan Johnson)合作。后者此前曾以8亿美元(约合54.2亿人民币)的价格,把自己的企业Braintree卖给了PayPal。约翰逊出资1亿美金(约合6.7亿人民币),两人共同成立了一家名叫Kernel的初创公司,专门研发人脑移植设备的原型产品。他们目前正在医院里的癫痫病人身上开展相关实验。伯尔格博士表示:“我们正在人类身上开展测试,已经取得了不错的初步成果。接下来我们将把该芯片变为商业化产品。”

但在把该产品用在健康人身上之前,该公司希望能先用该产品改善退化症患者的记忆力,如阿尔茨海默症患者等。约翰逊表示:“我们希望,如果你丧失了一部分记忆功能,你还能通过植入海马体假体来重建大脑回路,重塑你的记忆。我们将首先在记忆缺陷患者身上开展实验。”

人体大脑如何控制我们的语言功能?

当你开始阅读时,首先你会检查一下词汇,随后通过确定语境和意义来对词语进行解释,这项复杂的过程由很多大脑区域来参与;检测文字通常包括由视神经和其它神经束将来自眼部的信号运输到大脑后面的视觉皮质中。如果利用盲人点字法来进行阅读,你就会利用到大脑顶部的感觉皮层,如果你听别人在阅读,你就会用到距离耳朵不远的听觉皮质。 大脑中后部的系统区域能够帮助我们对文字进行解释,这其中就包括大脑顶叶中
