According to foreign media reports, California, scientists at Stanford University have developed a new circuit board, it can help people understand the real power of their own brains. This neural network is based on the human brain as a model, it is able to simulate 1 million nerve cells and billions of synapses, far exceeding other mimic the brain's equipment.

Currently being conducted by researchers at Stanford University BRAIN project was to develop new tools to measure brain activity. Neural mesh size as the iPad , and with 16 special "neuro-core" chips, the chips more efficiently than ordinary computer, and speeds up to 9,000 times.

Associate Professor of bioengineering at Stanford University Kwabena Boahen says: "from the standpoint of pure energy, the brain is hard to match. "Bioengineering Division but Boahen and his colleagues hope that this project could pave the way for progress in the field of Robotics and computer, and find new ways of understanding how the brain works.

Only individuals can understand human brain neural network programming, but Boahen plans to create a "neuro-compiler", which enables people with no knowledge of the neurobiology scientists were also able to use this device. Researchers at Stanford University now also developing a chip similar to neural network control of prostheses, this chip can decode brain signals directly to campaigns.

Boahen says neural mesh is currently the most cost-effective tools developed so far, but each loop circuit continues to spend roughly $ 400, now researchers are looking for ways to reduce costs. In any case, research of simulating the human brain still has a long way to go. Boahen says: "with neurons in the human brain is a neural network of 80,000 times, energy consumption only it three times. Achieve this level of efficiency is an ultimate challenge. ”

恐怖的“大脑”运算速度超PC九千倍

据国外媒体报道，加州斯坦福大学的科学家们发明了一种新的电路板，它能够帮助人们了解他们自己大脑的真正力量。这种神经网格是以人类大脑为模型的，它能够模拟一百万神经细胞和数十亿突触，远超其它模仿大脑的设备。

斯坦福大学的研究人员目前正在进行的BRAIN项目，就是为了研发出测量大脑活动的新工具。神经网格的大小与iPad相当，而且有着16个特制的“神经核心”芯片，这些芯片比普通电脑更高效，而且速度提升了9000倍。

斯坦福大学生物工程学副教授Kwabena Boahen称：“从纯能量角度来说，大脑非常难以匹配。”但是Boahen和他的生物工程师同事们希望，这个项目能够为机器人学和计算机领域的进步铺平道路，并且找到了解大脑如何工作的新方法。

目前只有了解人类大脑的个人才能够为神经网格编程，但是Boahen计划创造一种“神经编译器”，它能够使那些没有神经生物学知识的科学家们也能使用这种设备。斯坦福大学的研究人员们现在也在合作研发一种由类似于神经网格的芯片控制的假肢，这种芯片会将大脑信号直接解码为运动。

Boahen称，神经网格是目前为止研发出来的最合算工具，但是每个循环电路仍然耗费了大约400美元，现在研究人员正在寻找降低成本的方法。不管怎样，模拟人类大脑的研究仍然要有很长一段路要走。Boahen称：“人类大脑拥有的神经元数量是神经网格的8万倍，但消耗的能量只有它的三倍。达到这种能效水平是一项终极挑战。”
