Human Brain Project gets go-ahead, €1.19 billion over 10 years
- 2013-01-28 12:00:00
The European Commission has announced the selection of the Human Brain Project (HBP) as one of two new flagship science projects. The project will last 10 years and is expected to cost €1.19 billion. Half of the funding will come from the European Commission itself, the other half will come from the EU member countries and participating institutions. Around 80 institutions are involved. Together they will attempt to model the human brain and build a biologically-realistic simulation of it within a supercomputer. The project will start around September 2013 and full brain simulations are targeted for 2023.
Ray Kurzweil joins Google as a research director
- 2012-12-15 12:00:00
Ray Kurzweil announced yesterday that he's joining Google as a research director. He will work full time at the Google HQ in California. His work will focus on machine learning and language processing. Last month Kuzweil published a book titled How to Create a Mind. In turn, Google's long-term aim is to build a machine that is AI complete. So it makes perfect sense that Kuzweil and Google should team up.
Spaun - world's largest functional brain model
- 2012-11-29 12:00:00
Spaun is a simulated brain that contains 2.5 million neurons. This is far fewer than the 86 billion in the human brain, but enough to recognize lists of numbers, do simple arithmetic, and solve reasoning problems. The system is biologically realistic in its simulation of spiking neurons and neurotransmitters. As a result, it reproduces many quirks of human behaviour, such as the tendency to remember items at the start and end of a list better than those in the middle.
IBM simulation of 530 billion neurons and 137 trillion synapses
- 2012-11-14 12:00:00
Using 96 Blue Gene/Q racks of the LLNL Sequoia supercomputer (1,572,864 processor cores, 1.5 PB memory), IBM and LBNL achieved a simulation of 2 billion neurosynaptic cores. This simulation contained an unprecedented 530 billion neurons and 137 trillion synapses running only 1542x slower than real time. The attached image represents the simulated network of pathways between neuron clusters in macaque monkey brain.

The third part of Noah Hutton's excellent documentary about the Blue Brain Project was released today. This is a ten-part film, with one part being released every year. It follows the project team as they attempt to build a complete simulation of the human brain within a supercomputer. All parts can be viewed on the website: bluebrainfilm.com
Ray Kurzweil's new book published: How to Create a Mind
- 2012-11-13 13:40:00
This is a probably a must-read for anyone interested in how artificial general intelligence will be achieved. His basic premise is that the brain contains no hidden secrets and that the creation of sentient machines will follow from re-engineering the brain in non-biological form. Kurzweil estimates that the human neocortex contains 300 million pattern processors linked horizontally and vertically. He claims it is these processors, rather than the neurons of which they are composed, that are the fundamental units of the brain. Near-future computer technology could build a synthetic brain containing well beyond "a mere 300 million" processors, and instead as many as a billion or a trillion. Website: howtocreateamind.com
Brain simulations and the new TOP500 supercomputer list
- 2012-11-13 12:00:00
Twice a year a list of world's the top 500 supercomputers is released. Today the list was updated and the new Titan supercomputer in the US took top slot at 17.59 petaflops. Rising to 5th place, with 4.141 petaflops, is the JuQUEEN machine in Jülich, Germany. If the Human Brain Project is successful in securing EU funding in January 2013 then the brain simulations will be run on JuQUEEN. This machine is now around 100x more powerful than the supercomputer currently used by the Blue Brain Project in Lausanne, Switzerland. JuQUEEN (pictured here) should be powerful enough to simulate all 100 million neurons of a mouse brain.

Today version 0.70 was released and is available for free download.
Larry Page is personally funding worm brain emulation research
- 2012-04-18 12:00:00
David Dalrymple, a neuroscientist at Harvard, recently gave a guest lecture at Marvin Minsky's Society of Mind artificial intelligence class. David talked about his current research efforts to reverse engineer the C. elegans nervous system. During the Q&A session someone asked how the research is funded. To the surprise and amusement of the audience, David answered that it's personally financed by Larry Page (CEO of Google). The research was also Larry's idea.
Memristor-based artificial synapses built by HRL Labs
- 2012-03-23 12:00:00
A press release from HRL Labs today says they have demonstrated the first functioning memristor array stacked on a conventional CMOS semiconductor circuit. They say this hybrid circuit is a critical advance in developing intelligent machines. Ultimately the team plans to scale the neuromorphic chip to support millions of neurons and billions of artificial synapses. The paper, which was actually published in December, is titled: "A functional hybrid memristor crossbar-array/CMOS system for data storage and neuromorphic applications". The research is funded by the DARPA SyNAPSE program.
Web-based "Worm Brain/Body Browser" released
- 2012-03-21 12:00:00
OpenWorm is an attempt to build a complete cellular-level simulation of the nematode worm Caenorhabditis elegans. Of the 959 cells in the hermaphrodite, 302 are neurons and 95 are muscles. The simulation will model neuromuscular electrical activity as well as physical forces within the worm and from its environment. The project is treated a first step towards simulating whole biological systems including, ultimately, the human brain.
Digital brain in the works at Qualcomm
- 2012-02-15 12:00:00
Paul Jacobs, the CEO of Qualcomm, reveals an interesting update: "The team started out building a retina. They found it responded to optical illusions the same way a human does. They added another layer of cells and it started to find features. They added another layer, it started to find corners and oriented lines. Another layer, it started to find patterns. Today it tracks objects. It's not programmed, it's taught."
Artificial Brains: Not in this century
- 2012-02-04 12:00:00
this skeptical article was published yesterday by cognitive scientist Mark Changizi. One of his arguments is that we still don't understand the tiny nervous system of the Caenorhabditis elegans roundworm. If the functioning of these 302 neurons is beyond our grasp, even after decades of study, then we've no hope of soon understanding the many billions of neurons in a mammalian brain.
BrainScaleS machine shows its first spiking neural activity
- 2012-01-24 12:00:00
BrainScaleS is a European research project that is building neuromorphic hardware using wafer-scale integration. One wafer is designed to simulate ~50 million synapses, or up to 200,000 neurons. The wafer was delivered to Germany from the fab in Taiwan late 2011. Last week in the lab it displayed its first spiking neural activity. The wafer can be seen in the photo, encased behind an octagonal aluminium plate.

The proceedings of the 2nd European Future Technologies Conference and Exhibition were published online today. This conference marked the half-way point in the one-year pilot phase of the Human Brain Project (HBP). In the second half of 2012 the European Union will decide, via the FET Flagships program, whether to award .1 billion in funding for the project. If awarded, the HBP will become a ten-year attempt (2013 to 2023) to build a complete simulation of the human brain within a supercomputer.
Google X Lab has built an artificially intelligent robot
- 2011-12-05 12:00:00
Someone claimed today that Google has developed a robot that can pass the Turing Test 93% of the time. The claim was posted anonymously to reddit.com by a supposed former Google X Lab employee. The posting is most likely a hoax, but interesting reading nevertheless. It possibly contains some elements of truth, although we don't know which elements.
Silicon synapse built at MIT
- 2011-11-19 12:00:00
Today researchers at MIT announced they have built a silicon synapse that models the ion channels in a single biological synapse. It contains ~400 transistors and operates using analog current, not digital. They plan to use the chip to investigate how biological synapses are strengthened and weakened, and to build larger systems that model neural functions such as the visual system. See the news article and the research paper.
