Spinal cord is important in assuming signal transduction within the living body. There is a great deal of complexity with the mechanically properties of spinal cord tissue. The relationship between charged tissue, water and ions are unknown. Especially, electromechanical properties of spinal cord tissue that effect the stiffness of spinal cord have not been studied before. Spinal cord tissue containing proteoglycan generate streaming potential when compressed. Streaming potential is an indicator for showing the electromechanical properties. We measured streaming potential of spinal cord tissue in uniaxial confined compression, and we also measured the streaming potential in white matter and gray matter of spinal tissue. We obtained the relationship between the mechanical condition and streaming potential difference depending on the tissue of white matter and gray matter. And we measured electric potential amplitude when spinal cord tissue was applied to cyclic load. These tests were performed in saline at room air temperature and saline of 37℃.
