The development of a physical model of the rat whisker system (a). A prototype of the sensor system from which we can measure realistic whisker stimulus interactions is shown in (b). A somatotopic map for whisker direction measured across the horizontal extent of one layer 2/3 barrel field  is reproduced from  and shown in (c). (d) A layer 2/3 map that emerges in nine simulated barrel fields based on multi whisker inputs .
