WebThis led to a decrease in the ratio of grey to white matter stiffness. For very low forces and speeds relevant for cellular mechanosensing, I found grey matter to be stiffer than white matter in all three anatomical planes. Next, I assessed how spinal cord tissue stiffness measured with such low forces and speeds changes with the age of the rats. WebGray matter White matter Dorsal roots Tracts.
