A Star in the Brainstem Reveals the First Step of Cortical Magnification
Figure 4
Microelectrode recordings from PrV related to brainstem anatomy.
A–F. A series of sections through the brainstem showing the representation of the star in PrV and the locations of 2 microlesions made during the recordings (L1, L2). G. Drawing of the brainstem showing the star subnucleus in PrV and the locations of the microlesions made during recordings. H. Receptive fields for neurons responding at lesioned sites L1 and L2. Axes are approximate in “G” as the brainstem was rotated to obtain favorable sections (see materials and methods).
