Sexual Dimorphism of Ventricles of the Brain in Rajasthan Population

40 Male and 40 Female, normal adult age between 25 to 35 were selected for study. Their Ventricles of the Brain were studied with C.T Scan. Mean Values Height of Fourth Ventricle of males was 1.476 cm (SD ±0.008) and Females was 1.121 cm (SD ±0.013) and t=test result was 147.07 cm which was statistically highly significant (P < 0.001) Mean Value of width of fourth Ventricle of male was 1.628 cm (SD ±0.016) and females was 1.235 cm (SD ±0.014) and t=test Value was 118.30 cm which was statistically highly significant (P < 0.001) mean value of length of Right frontal horn of lateral ventricle of male was 3.265 cm (SD ±0.014) and female was 2.944 (SD ±0.159) and value of t=test was 12.68 cm which was highly significant P value (P < 0.001) and mean Value of length of left front horn of lateral ventricles in males 3.315 cm (SD ±0.012) t=test value was 148.63 cm which was highly significant P value (P < 0.001). Classification of Functional coefficient of a) Height of Fourth Ventricle in males was 7.72 E3 while in Females 5.23 E3. b) Width of Male fourth Ventricle coefficient was 2.37 E while female was 1.15 E. c) Coefficient Values of length of Right frontal horn of lateral ventricle in males was 171.9 and in females 148.6. d) Coefficient Values length of left frontal horn of lateral ventricle in males was 2.75 E4 and in Females was 2.52 E4.
