“activating synapses in a centrifugal sequence (outward from the soma) caused a different [lesser] [cortical pyramidal] neuronal response than activating the synapses in a centripetal (inward) sequence”

Imagine there are two referees who have different opinions about where a ball landed, in particular whether it went over some line. How can they cooperate to make a better decision than either one could individually?

(from 2003) Jaron Lanier talks about the “phenotropic” programme, which consists of trying to design software systems that uses pattern recognition, rather than protocols, for communication between components of the system.

Friend of the blog Jacob Robinson (who himself is pioneering impressive new techniques with nanowires for neural recording) writes:

While we’re all distributing scientific resources, I thought I’d point out that the KITP has a wonderful program on Emerging Techniques in Neuroscience, currently underway at UCSB. They have a great lineup of speakers with some overlap with the Allen Institute program. Videos of the talks are being posted online here.

So many good videos from good neuroscientists (including Chuck Stevens, John Hopfield, Clay Reid, Jeff Magee, Guoqiang Bi, and many more)… it’s going to take me a while to get through these. Enjoy!

The Allen Brain Institute (or is it in-situte?) has posted a nice series of video lectures from a few weeks ago with well-known scientists (George Church, Steve Smith, Christof Koch, Sydney Brenner, Catherine Dulac and others). The topic was a broad one — “What are the open questions in neuroscience?” — but one that is sure to be of interest to many who are trying to understand what the most important areas in neuroscience to work on (like those of us, for example, currently figuring out a postdoc project!)
