美国研究人员展示了一种无需手术和植入物的脑机接口技术，让4位参与者成功用思维控制计算机。该技术利用头皮记录的脑电图信号，结合特殊算法转化为操作指令。这一非侵入性的技术有望帮助残疾人操作轮椅或假肢，未来具有临床应用潜力。

用人脑控制电脑

　　Four people were able to control a computer using their thoughts and an electrode-studded thinking cap, U.S. researchers reported on Monday.

　　They said their set-up could someday be adapted to help disabled people operate a motorized wheelchair or artificial limb.

　　While experiments have allowed a monkey to control a computer with its thoughts, electrodes were implanted into the animal''s brain. This experiment, reported in the Proceedings of the National Academy of Sciences, required no surgery and no implants.

　　The results show that people can learn to use scalp-recorded electroencephalogram rhythms to control rapid and accurate movement of a cursor in two dimensions, Jonathan Wolpaw and Dennis McFarland of the New York State Department of Health and State University of New York in Albany wrote.

　　They tested their device on four people——two partly paralyzed men who used wheelchairs and a healthy man and woman.
