 Abstract: Over yonks, motor cortex were studied by stimulatory method, with the advent of functional Magnetic Resonance Imaging , a new road map is created in studying motor cortex of human brain by non- invasive technique. In this study functional topography of human face is constructed using Blood Oxygen Level Dependent Technique .Instructions were given to the normal individuals to perform various paradigms involving different parts of the body and the corresponding cortex of the brain are represented as glowing areas. The amount of motor cortex involved is directly proportional to the density of innervations and not the area of the body surface.
