Brains of primates show morphometric differences that may be influenced
by the process of functional complexity, evolution and adaptation. Comparative
topographic measurements of the primate brains have been used to explain
functional and evolutionary trends between the species and to highlight
differences in salient functions. Variations in selected linear measurements
of the human and baboon brains have demonstrated functional complexity.
Some neuro-pathological conditions of the brain may show characteristic
morphometric changes. Selected dimensional linear and curved measurements
of 4 human and 4 baboon brains from the superior, inferior and lateral aspects
were analyzed using ratios to evaluate variability in the morphology of the
brains. The ratios for the same species (linear vs curved) provide the extent
of the curvature on that measurement. This could be interpreted that more
curving suggests more neurons and greater volume. With inter-species ratios;
a bigger value implies a higher density of neurons or greater volume for the
aspect under consideration. Intra-species co-efficient of variation comparison
indicates that curved measurements had a higher variability than the linear in
both species. Comparison of symmetry in terms of ratios of both linear and
curved measurements indicated no significant difference between hemispheres
for both species. There was similarly no significant intra-species difference in
terms of curvature between the left and right aspects, but the measurement
landmarked by summit of central sulcus and inferior temporal gyrus showed
the highest difference in curved measurements. This study provides baseline
data for certain morphometric measurements that may be used to assess
pathological changes in brain disorders as found in imaging studies. Ratios may
also be used to show structural, functional and evolutionary differences and
trends between primate brains.
