Direction Preference map present in default network architecture.

<p>The distribution of neuron preference for directional selectivity exhibits a similar patchy pattern to experimentally derived maps. In addition features seen in experimental maps such as regions of rapidly and smoothly changing preference (box 1), fracture lines with abrupt switch to opposite preference (box 2) and saddle points (box 3) are present. The letters a, b and c refer to neurons whose tuning curves are shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0102908#pone-0102908-g004" target="_blank">Fig 4</a>.
