Comparison of Vascular Densities of The Human Cerebellum – A Pilot Study
Vascular density corresponds to metabolic demands, which increase in highly active areas of the brain. The aim of this study was to determine the surface vascular density of three equal vertical divisions of the superior and inferior cerebellar hemispheres and to correlate with the function.
The dye Araldite was injected to the carotid and vertebral arteries of four fresh adult male human brains, maintaining a constant pressure of 93 mmHg. The cerebellums were examined, and a count was made, from the number of vessels entering each square on an overlying grid, using the light microscope and the camera Lucida. The vascular density of the three vertical columns were calculated and compared. The mean values of the vascular densities of the three vertical columns were, vessels per mm2 (from medial to lateral) left superior – 1.67, 1.89, 1.54, right superior – 1.52, 1.52, 1.28, left inferior – 1.17, 1.30, 1.19, right inferior – 1.14, 1.42, 1.55, in respect of each hemisphere. (P>0.05) This pilot study reveals that there is no statistically significant difference between the vascular densities of three equal vertical columns in each cerebellar hemisphere.
