Anatomical studies on the corpus geniculatum laterale in the Indian buffalo (Bubalus bubalis)

The CGL of the buffalo was convex, swung in a semicircle around the thalamus and was covered by the fibres of the optic tract. It was distinctly laminated, possessing a maximum number of 5 cellular laminae. The individual cell layers were separated from each other by clearly defined myelin interlayers. Laminae I and II were magnocellular and Laminae III, IV and V were parvicellular. No significant difference was found in the diameters of the neurons of the corresponding laminae of the two sides of CGL of the same specimen. From degeneration studies it was observed that the retina projected contralaterally to laminae I, III and V and ipsilaterally the input was to laminae II and IV with little or no overlap.
