Figure 7.
The homology of the VLN in cat and rat, illustrated as a transformation of the rat IC (top) into the cat IC (bottom). The white contours in the CNIC and VLN indicate a frequency-specific laminated projection. The middle diagram shows the addition of lower frequency sensitivity to the dorsolateral aspect of the CNIC. This enlargement encroaches on the space occupied by the dorsal VLN, pushing it ventrally. Drawings are not to scale.
