Read brain software system, real-time decoding of brain information accuracy rate of 95% (video)

Read brain software system can decode the accuracy rate of brain information in real time 95% scientists have recently designed a set of computer software, connected with the brain implanted electrode, can read the human brain information in milliseconds. Tencent science news, according to the British Daily Mail reported that, at present, scientists developed a new computer program, real-time decoding of human brain thinking content, the accuracy rate of 95%. They are able to predict the electrical signals of the brain implanted electrodes, and help to communicate with people who are not sensitive to change. This decoding only occurs in milliseconds between people who see images, and the accuracy rate is over 95%. The United States University of Washington neuroscientist Luojiexi Rao (Rajesh Rao) said: "we are trying to understand, first, the human brain temporal lobe to perceive objects; second, how people use computers to extract the information, and the real-time prediction of what people see objects. From a clinical point of view, you may think that the findings are a conceptual validation of the mechanisms of patient communication and communication, including paralysis, stroke, and people who are totally insensitive to change." The scientists analyzed the neural responses to two types of visual stimuli (facial and house images), allowing scientists to predict which images were patients’ views and the time to watch, and the accuracy rate was 95%. At present, this research report is published in the recently published public library of Science: computational biology. The results of this study are obtained from analysis of 7 patients with epilepsy care on the Harborview Medical Center on the University of Washington medical Geoff – Otjeman (Jeff neurosurgeon Ojemann), each patient had seizures, and drug treatment has not eased, so they accepted the temporary temporal lobe of the brain implant surgery, duration about 1 weeks, to focus electrode seizure localization. The temporal lobe is responsible for sensory input and is associated with seizures, which are located in the eyes and ears of mammals, and are also associated with Alzheimer’s disease and are more susceptible to head injuries than other brain structures. In this experiment, the electrodes implanted into the temporal lobe are connected with powerful computer software to extract two intrinsic brain signals: event-related potentials and broadband spectral changes. Rao described that event related potential signals may be activated by thousands of nerve cells when people first see the image, and the broadband spectral change signal is the continuous information processing after the initial information wave. By looking at the computer display, we’ll see random sequences of images – human faces and houses flashing images, we get differential responses to different implantation electrodes, some electrodes are very sensitive to human faces, and some electrodes are sensitive to houses. The computer software uses 1000 times per second to sample and digitize brain signals to extract relevant features. At the same time, the software can analyze the signal data and combine the electrode position with the signal type to analyze each image that people really see. Statistical results show that the accuracy rate of software image recognition is as high as 95%. Rao stressed that the latest research brain

读脑软件系统能实时解码大脑信息精确率95%科学家最新设计一套计算机软件,与大脑植入电极连接在一起,可以几毫秒之间读取人类大脑信息。腾讯科学讯 据英国每日邮报报道,目前,科学家最新研制一套计算机程序,能够实时解码人类大脑思考的内容,其精确率达到95%。他们能够预测到大脑植入电极的电子信号,并且有助于“对变化不敏感”患者进行交流沟通,这一解码过程仅发生在人们看到图像的数毫秒之间,其精确率达到95%以上。美国华盛顿大学计算神经系统科学家罗杰西-拉奥(Rajesh Rao)说:“我们试着去理解,第一,人类大脑颞叶区域如何感知物体;第二,人们如何使用计算机提取这些信息,并实时预测人们所看到的物体。从临床诊断角度,你可以认为该研究结果是构建患者通讯交流机制的概念验证,这些患者包括瘫痪者、中风者以及完全对变化不敏感的人群。”科学家对患者的两种类型视觉刺激(面部和房屋图像)的神经反应进行了分析,使科学家能够随后预测哪些图像是患者观看过的,以及观看的时间,结果显示其精确率达到95%。目前,这项研究报告发表在近期出版的《公共科学图书馆——计算生物学》上。这项研究结果是基于对美国港景医疗中心7位接受护理的癫痫患者观察分析获得的,华盛顿大学医学神经外科医师杰夫-奥杰曼(Jeff Ojemann)称,每位患者曾出现癫痫发作,并且药物治疗并未缓解,因此他们接受了临时性大脑颞叶植入电极手术,持续时间大约1个星期,电极能够定位癫痫发作的聚焦点。颞叶负责处理感觉输入,与癫痫发作有关,该组织位于哺乳动物眼睛和耳朵之后,同时,它也与老人痴呆症相关,比其它大脑结构更易受到攻击形成头部创伤。在这项实验中,植入颞叶的电极与强大的计算机软件建立连接,能够提取两种固有的大脑信号:事件相关电位和宽带光谱变化。拉奥描述称,事件相关电位信号可能是人们最初看到图像时由数千个神经细胞共同激活的,宽带光谱变化信号是最初信息波之后的持续信息处理。通过观看计算机显示器,将看到随机序列图像——人类面部和房屋的闪烁图像,我们获得不同植入电极位置的差别反应,一些电极对人类面孔非常敏感,一些电极对房屋非常敏感。这个计算机软件每秒1000次采样和数字化大脑信号,从而提取相关特征,同时,该软件还能分析信号数据,从而将电极位置和信号类型结合在一起,分析出人们真实看到的每个图像。统计结果显示,软件识别图像的精确率高达95%。拉奥强调称,最新研制的计算机软件有助于实现对瘫痪患者的沟通交流。(悠悠 编译) 【科学派】你究竟能不能锻炼你的大脑相关的主题文章:
