据5月29日发行的英国学术杂志《自然》上刊登的论文，美国研究机关通过直接从猴子的脑部获取的脑波，成功地让猴子
通过意识来自由地操作机械臂。
进行这个实验的是美国匹兹堡大学（University of ...
恐怖的米帝，可怜的猴子

方向性错误，这是日人做的事情。
美国人会给猴子穿上机械护甲，然后加上枪炮，然后............................
脑波操作~~~~~~~~恐怖啊
我会用脑波让PLNN投怀送抱:victory:
这个实验室没听说由军方背景(当然,咱不是很八卦的人)

Arm movement is well represented in populations of neurons recorded from the motor cortex1, 2, 3, 4, 5, 6, 7. Cortical activity patterns have been used in the new field of brain–machine interfaces8, 9, 10, 11 to show how cursors on computer displays can be moved in two- and three-dimensional space12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22. Although the ability to move a cursor can be useful in its own right, this technology could be applied to restore arm and hand function for amputees and paralysed persons. However, the use of cortical signals to control a multi-jointed prosthetic device for direct real-time interaction with the physical environment ('embodiment') has not been demonstrated. Here we describe a system that permits embodied prosthetic control; we show how monkeys (Macaca mulatta) use their motor cortical activity to control a mechanized arm replica in a self-feeding task. In addition to the three dimensions of movement, the subjects' cortical signals also proportionally controlled a gripper on the end of the arm. Owing to the physical interaction between the monkey, the robotic arm and objects in the workspace, this new task presented a higher level of difficulty than previous virtual (cursor-control) experiments. Apart from an example of simple one-dimensional control23, previous experiments have lacked physical interaction even in cases where a robotic arm16, 19, 24 or hand20 was included in the control loop, because the subjects did not use it to interact with physical objects—an interaction that cannot be fully simulated. This demonstration of multi-degree-of-freedom embodied prosthetic control paves the way towards the development of dexterous prosthetic devices that could ultimately achieve arm and hand function at a near-natural level.

有线塞可谬。
看看米国人现在的技术储备吧，动力外骨骼，人造肌肉，机器骡，脑波操纵机械，整合起来是什么啊？精神力高达？当然啦，是小型化的。

彼此彼此。TG老早以前不是也报道过在做鸽子脑袋里插电极控制其飞行的实验吗。现在米帝更上一层楼鸟。TG、米帝加油，早点把人造人搞出来吧...
通过奖励惩罚直接刺激来让动物学习简单动作跟识别神经信号驱动机械装置完成动作，不是一回事吧
美帝的强大不在于科技实力，而是其宣传机器。瞧瞧几位，都看到瑟瑟发抖了。
人类能训练猴子完成简单动作也可以利用大脑信号传输操作机械，把两样东西放在一起就成了外星科技了？果真如此那些早已应用到瘫痪病人身上的实验装置就成了不可能完成的任务了，清华也别搞什么脑机了，把那博士送回美国去吧。
控制鸽子和这个不是一回事。那是通过在鸽子脑部直接连接控制单元，通过电信号刺激鸽子神经动作。这个更复杂些，复杂地方不在于脑部手术，而是分析筛选大量脑部信号。所以现在只能做到类似利用手臂动作开关灯这类的实验，就是你想动作手臂，然后控制开关。还做不到想ABC就能出现在屏幕上的程度。

清华那玩艺,各位就不要做梦了
EEG是没有前途的

如果这台设备只是能识别简单的脑波信号，并由脑波信号的刺激做一些早己被设定好的机械动作也没什么值得炫耀的。但是，如果这个机械臂上面安装有类似人体神经系统那样的触觉接点，并能把这些节点所感知到的触觉感受经由人造神经系统重新传回脑部，并根据这些外部信息作出空间判断来控制那个机械臂，那就恐怖了。
