Caption:
This inferior to superior view (looking from the feet to the top of the head, with the subject's nose towards the top of the image) colour image demonstrates the normal appearance of the corpus callosum which is the largest commissural tract in the brain, meaning it connects one side of the brain to the other. By convention the colour is coded so that blue indicates fibre tract direction in the superior (top) to inferior (bottom) direction, red indicates right to left (horizontal) fibre tract orientation and green indicates fibre tract directionality from anterior (front) to posterior (back).
