Abstract

Identification of an individual is of utmost importance in cases of mass disasters. In such cases determination of sex reduces the field of search to 50% of the population as it eliminates one gender from the said population. Many Parameters are used for sex determination. In this regard various body structural measurements are used for sexual dimorphism. We attempted to find out sexual differences in various measurements of Carpus callosum of brain. The right half of the brain dissected during autopsy was preserved in 10% formalin. The following measurements were recorded using a digital sliding caliper before and after fixation of brain did not reveal any significant differences: Frontal pole to occipital pole [FO], Length of corpus callosum [GS], Frontal pole of brain to the corpus callosum [FG], Occipital pole to corpus callosum [OS], Genu of corpus callosum to the column of the fornix [GC], Splenium of corpus callosum to superior colliculus [SSc]. Data was analyzed using the Statistical Package for Social Sciences (SPSS), version 16.0. Statistically significant difference was observed between the mean values of all the parameters of corpus callosum between the males and females. Hence, the dimensions of carpus callosum can be used to determine sex whenever necessary along with other parameters of sex determination
