"Changing Brains" example animations

    These images, animations and references are for a Brain Development Lab video project called "Changing Brains" about the interactions between experience and brain development in children. They  illustrate the modularity of various brain functions.

Euglena Academy's fall program

Wed, 2008-09-24 09:06 — Mark Dow

 

Euglena Academy's fall program is out, see below. I'm going to try to get to a couple of the Cozmic Pizza presentations.

Euglena Academy is an independent, college-level school for adults (18+) in Eugene, Oregon offers scientifically rigorous classes (beginning & advanced) and workshops about systems sciences (also known as complexity).

Human brain animations

 

Resources for, and animations of, a human brain. These are primarily surface renderings from MRI volume data. Space Software was used for most manipulation and rendering.

Description of remove_background_peak_image.m (MATLAB)

See attached code file, remove_background_peak_image.m.

[ vPeak fFWHM_range imZeroBackground ] = remove_background_peak_image( strInputFilename, fFWHM, bShow )

2x2 symmetric L-systems

"Symmetry is a complexity-reducing concept; seek it everywhere." Alan Perlis

   The simplest 2x2 replacement systems with rules that are globally and locally symmetric.
   
    Many other types of systems also have a large number of symmetries, for example:

Bridge Thin photography

Sun, 2008-06-29 00:07 — Mark Dow

Doug Heiken and I took some video and still photos of forest land near the Blue River Resevoir, OR, that will be thinned, with the intention of re-photography after the thin. These are related notes and materials.

A 90 year old forest of mostly Douglas fir that was naturally established after fire about 90 years ago. This area will be thinned as part of the Bridge Thin timber sale, probably in late 2008 or 2009. The prescription is 17 foot "designation by description." Unit 82 and part of unit 80 are included in the polygon (see below).
