A strategy for mapping biophysical to abstract neuronal network models applied to primary visual cortex
Fig 2
Cortical domain containing 4 hypercolumns that provides the reference geometry for the 2D model A; the dots mark the pinwheel centers; the colors mark the orientations coded by bars in the legend.
To obtain an activity profile in orientation space the 2D model activity is projected to the ring shown at the lower left quadrant.
