Fuzziness and Regularity in the Microfeatures of Cerebellar Nervous System

Abstract

To understand the anatomy of the nervous system, the neuron (nerve cell soma, dendritic processes, andaxon), and synoptic terminals must be studied. In the present study a freeze-drying device was applied to t-butyl alcohol substituted nerve cells, fibers and synoptic terminals in the human cerebellar cortex. Two types of nerve cells were observed: a flat polygonal cell, and many small round granule cells. A flat polygonal cell was surrounded with many granule cells. This cell soma with many synoptic terminals was revealed and micrographed using a scanning electron microscope (SEM). The results of measurements of these fuzzy microfeatures using an image analyzing software were reported. The granule cells varied in shape, but with many fibers. These microfatures showed fuzziness in shape, and differences between the flat polygonal cell and granule cells.
