DS_Post_Fac.x.1  This variation was developed for tutorial exercises. The orientation map has been rotated so that there is an orientation pinwheel in the center of the map. The model has a 4x4 DS population, with a range of preferred directions represented. The EX to DS weights are set by a Gaussian distribution with prob 1.0, so there is almost complete all-to-all EX to DS connectivity within a space and orientation bandwidth range of cdist 70 microns and cori 20 deg.
