Figure 6. Layer-specific dynamics of suprathreshold RF structure.

The grid of white lines indicates the barrel field, with the intersection representing the centre of the barrel with the principal whisker aligned in the middle. Surround whisker responses were normalized to the principal whisker response. The black lines delineate the areas equal to 80 (inner contour) and 50% (outer contour) of the maximal principal whisker response. Responses were normalized to the peak response within each layer. The numbers indicate average evoked response (APs per cell per stimulus) for the time window in which maximal firing was observed.
