ABSTRACT
Design-based stereological methods (the Cavalieri principle and vertical sectioning) for estimation of volumes and surface areas were applied to fixed Bactrian camel brains. Brains from 10 subjects were hemisected. Cerebrum hemispheres and cerebellum halves from both sides were sliced systematic randomly for Cavalieri estimates of volume and vertical sectioning estimates of cortical surface area. Weights and linear dimensions were also recorded. The differences between left – right hemispheres and cerebellum halves did not show statistical significance (P>0.05). For cerebrum (both hemispheres combined) the average volume was 446 cm3 and cortical surface area was 1264 cm2. One thirds of this surface was hidden within sulci. Cortical volume was 222 cm3 with arithmetic mean thickness of 2.3 mm. The cerebellum occupied 38cm3 with a cortical surface of 396cm2 of which 70% was hidden in fissures.
Key words: Bactrian camel, cerebellum, cerebrum, morphology, stereology
