The DARPA Systems of Neuromorphic Adaptive Plastic Scalable Electronics (SyNAPSE) program, started in 2008, has the goal to develop electronic neuromorphic machine technology that scales to biological levels. This section covers initiatives in SyNAPSE and in related projects that use new technologies to implement artificial neural systems at biological scale and power.

  • MoNETA and “the C word”

    By Sean Lorenz | December 7, 2010

    By Sean Lorenz, Heather Ames & Massimiliano Versace

    After the IEEE Spectrum article on MoNETA was released, a number of websites and blogs picked up the story. Many of the comments on these sites express passionate opinions spanning a wide swath of targets – memristors, Moore’s Law, the state of current AI, among other science-specific inquiries. There is one topic, however, that has made the Slashdot comments section go into the triple digits. Most neuroscientists I know refer to it simply as “the C word”…yep, consciousness. Gasp!

    You bring up “the C word” to any tenured neuroscientist and he or she will chuckle, turn on the pedantic tone of voice, and say something like: “No self-respecting scientist can attempt to study things like consciousness. It’s a waste of time; leave those petty issues to the philosophers!” The MoNETA project has opened up a new can of worms with regards to artificial consciousness and rightfully so. The BU team working on MoNETA has also thought extensively about the dreaded C word with relation to neuromorphic chip technology, which is why Max Versace, Heather Ames, and I wrote a paper about it (and later presented our ideas at the 2010 Interdisciplinary Graduate Conference on Consciousness). Here is the original paper, “Consciousness and Neuromorphic Chips: A Case for Embodiment,” in its entirety. If you'd rather watch it in video form, just scroll down to the bottom and your wishes will be granted. Read the rest of this entry »

  • MoNETA IEEE article: a summary until now

    By Massimiliano Versace | December 5, 2010

    The online version of the IEEE Spectrum article describing our work on the MoNETA project (withing the DARPA SyNAPSE grant) has been out for a bit more than a week, and the story is starting to generate many comments and being picked up by blogs and magazines (see Slashdot and Popular Science). May be it's time to summarize what is happening, and starting to address the many comments related to the article. Ben and I will start a series of posts on the topic, this one being the first.

  • Neurdons on IEEE Spectrum cover page!

    By Massimiliano Versace | November 23, 2010

    December won't be a boring month for Neurdons. Two of us (who is writing, and Ben Chandler) will be featured in the cover page, back page story, and in an article title "MoNETA: A Mind Made from Memristors. DARPA's new memristor-based approach to AI consists of a chip that mimics how neurons process information" on the December issue of IEEE Spectrum. The preview of the article has appeared online.

  • Brain emulation road map … or not

    By Massimiliano Versace | November 22, 2010

    No, I am not going to argue that that somebody has figured out the brain road map to building a human-intelligence level chip. Actually, me and many of the people deeply involved in the endeavor of building software and hardware to emulate biological intelligence are too busy with the immense hurdles of getting even the most elementary levels of intelligence to work, that there is no time to speculate on when we will be done. Nevertheless.... Read the rest of this entry »

  • Boston University Team SyNAPSE presentation, August DARPA site visit

    By Massimiliano Versace | September 8, 2010

    This post contains the videos of the Boston University team presentation during the recent DARPA SyNAPSE site visit occurred in August 2010, in Palo Alto. This presentation talks about the ongoing projects undertaken by the Boston University team in SyNAPSE since March 2010, with some of our most recent results and plans for the near future.

  • Leon Chua visits the Boston University SyNAPSE team

    By Massimiliano Versace | June 2, 2010

    Leo Chua gave one of his brilliant talks on May 21, 2010 at the ICCNS 2010 conference at the Department of Cognitive and Neural Systems. Just to be sure you get the magnitude of the event: Leon Chua is the first to theorize the existence of memristors with his paper "Memristor: The Missing Circuit Element" on IEEE TRANSACTIONS on Circuit Theory, published in September 1971.

  • Beyond cats

    By Massimiliano Versace | April 19, 2010

    One of the main motivation of the Neurdon blog is to shed light on the true innovative force behind the introduction of new computing paradigms based on the nervous system functioning. This is why when neurdons read the word cat associated with large-scale simulations, we get a little sad... readers should know that the greatest revolution that will see AI and the semiconductor industry jointly turn upside down our current use of intelligent machines has nothing to do with a bunch of cats. Though, according to PHYSORG article "Cat brain: A step toward the electronic equivalent", the pinnacle of memristor-based computer evolution will be a cat. IBM's "Max" (no, not Max Versace... apparently my shortened name is widely used to name unaware felines across the globe...) will be in good company. Read the rest of this entry »

  • Robotics and memristors

    By Massimiliano Versace | February 20, 2010

    Patrick Cox is the author of a very interesting article on Contrarianprofits.com. In the post, Cox makes the case that the time is ripe for large-scale adoption of robotics in both civilian and military applications.The latter is old news: in previous posts, we looked at the growing opportunities, and concerns, of robotic applications in dangerous (or dangerously boring) domains.

  • Why simulating a cat when we can simulate a human (or even more!)

    By Massimiliano Versace | November 26, 2009

    eugenebrainWhen I read (and wrote about) the recent controversy between Modha and Markram, I had this inescapable déjà vu feeling....weird, where did I hear that somebody already simulated a "brain" of the scale of the human brain? Of course!.... Eugene Izhikevich, a very bright (and VERY funny) neuroscientist that, in 2007, visited our center CELEST. During that visit, he showed what at that time (in 2005, and may be up to today) was one of the "largest scale" neural simulation. Read the rest of this entry »

  • Cat fight over blue brain

    By Massimiliano Versace | November 24, 2009

    cat_fightIn my recent post, I commented on IBM's announcement at the Supercomputing Conference (SC09) in Portland, Ore., that they had simulated a brain with the number of neurons and synapses present in a cat's brain. It looks like the controversial statement of IBM being finally able to "simulate a cat's brain" (or however their original statements has been distorted) has been stirring some more comments. Henry Markram, the leader of the Blue Brain project at EPFL, Lausanne, sent an open letter to IBM CTO Bernard Meyerson, along with several media (UK Daily Mail, Die Zeit, Wired, Discover, Forbes). One big question is: was Modha's statement somehow distorted? Did he actually simply claim that IBM simulated a system that has the same number of neurons of a cat, as opposed to simulate "the cat's brain?". This is an important distinction. Anyway, Neurdons must know, so here it is! Enjoy!
