In order to define mechanism of nerve damage which ascribable dynamics stimulation, brain tissue under the dynamics stimulation is visualized by immunofluorescence staining and observing brain damage with the use of confocal laser microscope(CLSM). In this study, we conducted following compression experiments and impact experiments by using pig brain from slaughterhouse. Cell body, nerve fiber and nuclear were observed by the CLSM. In cerebral nerve under compression strains of 50%, tear of axon and rupture of cell body occurred. Capillary vessel intrudes cell body in compression strain of 40%. Injury occurred in this case. Tear occurred in axon under compression strain of 30% in the CLSM image. Injury occurred in cell body under compression strain of 20%. Tear of axon on brain surfaces occurred in cerebral nerve under impact load. However, injury did not occur in deep part of brain tissue.
