One of the most important distinctions between neural architecture and present-day computing architecture is that brains appear to be built out of computing elements that do both processing and memory storage, whereas present-day computers have separate memory and CPU components (this separation is a key feature of what is called the “von Neumann” architecture). This separation means that computation is often rate-limited by the speed at which information can be transferred between memory and the CPU... neurodudes blogs http://www.medworm.com/rss/comments.php?id=4536195 Wed, 02 Mar 2011 05:26:10 +0100 4536195 http://www.medworm.com/index.php?rid=3059818&cid=t_167838_122_f&fid=35066&url=http%3A%2F%2Fneurodudes.com%2F2009%2F12%2F04%2Fibm-cat-brain-simulation-scuffle-symbolic%2F You’ve probably read by now about the announcement by IBM’s Cognitive Computing group that they had created a “computer system that simulates and emulates the brain’s abilities for sensation, perception, action, interaction and cognition” at the “scale of a cat cortex”.    For their work, the IBM team led by Dharmendra Modha was awarded the ACM Gordon Bell prize, which recognizes “outstanding achievement in high-performance computing”. A few days later, Henry Markram, leader of the Blue Brain Project at EPFL, sent off an e-mail to IBM CTO Bernard Meyerson harshly criticizing the IBM press release, and cc’ed several reporters. This brought a spate of shock media into the usually placid arena of computational neuroscience reporting, ... neurodudes blogs http://www.medworm.com/rss/comments.php?id=3059818 Fri, 04 Dec 2009 21:48:17 +0100 3059818 http://www.medworm.com/index.php?rid=1442957&cid=t_167838_132_f&fid=35011&url=http%3A%2F%2Ffeeds.feedburner.com%2F%7Er%2Fmndoci%2F%7E3%2F290724664%2F Matt Wood has a great great screencast of a talk around some very relevant problems (things that touch my interests as a blogger and in my day job as well). No surprise that I agree with him on the importance of distributed data and how we can start leveraging the web for a field that gets more and more data intensive by the day.

While a simple spreadsheet or modest database remains sufficient for some research, problems in the domain of “computational science,” which explores mathematical models via computational simulation, require systems that provide huge amounts of data storage and computer processing (current research areas in computational science include climate modeling, gene sequencing, protein mapping, materials science and many more). As an added hurdle, this level of computational infrastructure is often not affordable to research teams, who usually work with significant budgetary restrictions. Those words ... business|bytes|genes|molecules blogs http://www.medworm.com/rss/comments.php?id=1396264 Thu, 24 Apr 2008 13:24:27 +0100 1396264 http://www.medworm.com/index.php?rid=1147440&cid=t_167838_107_f&fid=36698&url=http%3A%2F%2Fminingdrugs.blogspot.com%2F2007%2F09%2Fprotein-foldinghome.html Folding@Home saysWhat is protein folding and how is folding linked to disease? Proteins are biology's workhorses -- its "nanomachines." Before proteins can carry out these important functions, they assemble themselves, or "fold." The process of protein folding, while critical and fundamental to virtually all of biology, in many ways remains a mystery. Moreover, when proteins do not fold correctly (i.e. "misfold"), there can be serious consequences, including many well known diseases, such as Alzheimer's, Mad Cow (BSE), CJD, ALS, Huntington's, Parkinson's disease, and many Cancers and cancer-related syndromes. You can help by simply running a piece of software. Folding@Home is a distributed computing project -- people...

Some recent papers may help shed some light on the subject. Models of the computational properties of local networks of neurons are starting to come into their own. This year has already seen at least two articles published in experimentalist journals based on the same core of theoretical work. To bring you up to speed, I need to remind you what is going on in the world of experimental neuroscience. Experimentalists are now able to record the single-cell activities of a whole population of neurons simultaneously. From Briggman, Abarbanel, Kristan (2006): By using multi-electrode arrays or optical imaging, investigators can now record from many individual neurons... neurodudes blogs http://www.medworm.com/rss/comments.php?id=486197 Tue, 20 Feb 2007 20:24:48 +0100 486197
