A volumetric study of hippocampus in cadaveric human brains

ABSTRACT

Background: Hippocampus is one of the key parts of limbic system. It is located in the floor of the inferior hornof lateral ventricle.Materials and methods: The study is conducted on 50 Hippocampi removed from 25 cadaveric brains in MedicalCollege Baroda, Gujarat. The volume of each is measured by water displacement method.Results: It is observed that the mean volume for the sample is 2.26+0.88cc. The mean volume on right side is2.37+0.88cc and on the left side is 2.12+0.88cc. The mean volumes seen in male and female hippocampi are2.14+0.70cc and 2.52+1.21cc respectively. The mean volume in the age group 60-80 years is 2.55+0.65cc and inthe age group 81 years onwards, it is 2.0+1.03cc. The difference in volumes of the two age groups is found to bestatistically significant.Conclusion: The study will be useful to anatomists, Neurologists, Neurosurgeons and psychiatrists alike.
