A Star in the Brainstem Reveals the First Step of Cortical Magnification
Figure 3
A star pattern visible in PrV.
A. Half of the star rotated 90 degrees counterclockwise showing the 11 rays that ring the nostril. The relatively small 11th ray acts as the tactile fovea. B. When the brainstem is properly oriented (see materials and methods) sections reveal 11 distinct modules in PrV.
