中文简介:
是否有可能根据他们当前的大脑活动来预测一个人的想法 - 甚至他们打算做什么?最近的进展使得可以从功能磁共振成像(fMRI)数据解码和预测人的想法。关键是每个想法都与一个独特的大脑激活模式相关联,可以用作签名或特定思想。可以训练模式分类器以识别这些特征签名,从而仅从他们的大脑活动中读出一个人的想法。这项研究可以揭示精神内容的神经表征是如何在大脑中存储和转化的。它还产生了许多潜在的应用,例如通过大脑活动控制计算机和人工假体或检测隐藏的精神状态。
课程简介: Is it possible to predict what a person is thinking of - or even what they are planning to do - based alone on their current brain activity? Recent advances have made it possible to decode and predict a person's thoughts from functional magnetic resonance imaging (fMRI) data. The key is that each thought is associated with a unique brain activation pattern that can be used as a signature or for that specific thought. It is possible to train pattern classifiers to recognize these characteristic signatures and thus read out a person's thoughts from their brain activity alone. This research can reveal how neural representations of mental contents are stored and transformed in the brain. It also gives rise to many potential applications, as for example in the control of computers and artificial prostheses by brain activity or in the detection of concealed mental states.
