Somatic sensory cortex of hyrax (Procavia).

Somatic sensory (SI) cortex was mapped in hyraxes by micromapping methods developed and used earlier in slow lorises and llamas. The somatotopic pattern of organization was similar in its general features to that found in other mammals. The perioral and intraoral representations are relatively large in SI of hyrax and exhibit considerable distortion. Sulci are reliable landmarks demarcating boundaries of SI in hyrax as they are in other mammals.
