Figure 1. Somatotopic functional maps in the rat S1 cortex.

Figure 1

Activated S1 areas after electrical stimulation of forepaw (FP, yellow), hindpaw (HP, green), whisker pad (Barrel, purple), and nose (Nose, red) are represented in 3D contour (B) and 2D coronal t-maps (C-F). The established S1 somatotopic map (A) matches 3D functional contours of the four body parts (B). Four 2D slices were selected across the four S1 subdivisions (A). Coronal 2D t maps (C-F, left panel) are shown with the time course of BOLD signal changes (C-F, right panel) in each S1 subdivision. The BOLD signal was normalized to baseline as 100.
