Area of Science:

  • Neuroscience
  • Anatomy
  • Gerontology

Background:

  • Stereologic techniques are crucial for analyzing nervous system anatomy, particularly in the aging brain.
  • The hippocampus remains a key area of interest for understanding aging processes.
  • Hippocampal morphology research is vital for future aging studies.

Purpose of the Study:

  • To determine the weight and volume of the left hippocampus using stereology.
  • To provide quantitative data on hippocampal anatomy in the context of brain aging.

Main Methods:

  • Stereological techniques were applied using a light microscope.
  • The Cavalieri method was utilized for individual volume estimation.
  • The mean coefficient of error for volume estimation was calculated.

Main Results:

  • The mean weight of the encephalon (excluding the cerebellum) was 6.1 ± 0.1 g.
  • The mean weight of the left hippocampus was 0.28 ± 0.02 g.
  • The mean volume of the left hippocampus was 0.28 ± 0.02 cm³.
  • The mean coefficient of error for stereological volume estimation was 0.03.

Conclusions:

  • The applied stereological technique provides reliable measurements of hippocampal volume and weight.
  • These findings contribute quantitative data to the understanding of hippocampal anatomy in aging.
  • The methodology may assist clinicians in evaluating aging-related brain changes.
