Signal changes were observed within contralateral primary motor cortex in subjects of control group. The maximal signal pixel time-signal curve was the same to the movement of BLOCK model.
This paper presents a simplified mathematical model for describing the water block mechanism and its influences, based on Darcy's formula and relative permeability curve and capillary pressure curve.
