Cortical Column is a new blog by computational modeler and volleyball freak Brian Mingus - check out the interesting posts on "The Simulation Argument" and Deep Pressure Stimulation, which is argued to simulate deep brain stimulation of intralaminar thalamic nuclei - noninvasively!

In the new issue of Seed, Douglas Hofstadter talks about "strange loops" - his term for patterns of level-crossing feedback inside some medium (such as neurons) - and their role in consciousness. Likewise, Gerald Edelman has talked about how a "reentrant dynamic core" of neural activity could…
In my post yesterday, I briefly mentioned the problem with simulations
as a replacement for animal testing. But I've gotten a couple of self-righteous
emails from people criticizing that: they've all argued that given the
quantity of computational resources available to us today, of course
we can…
Last week, a team of computer scientists led by Dharmendra S. Modha announced what sounded like an impressive breakthrough for neuroscience-inspired computing:
Using Dawn Blue Gene / P supercomputer at Lawrence Livermore National Lab with 147,456 processors and 144 TB of main memory, we achieved a…
The image on the right is a supercomputer simulation of the microcircuitry found within a column from the neocortex of the rat brain.
The simulation is a tour de force of computational neuroscience: a single column is a highly complex structure, containing approximately 10,000 neurons and 30…
