Using a technique called cinemorphology, this presentation illustrates the organic structure of the human brain. In the process, a brain is first imbedded in plastic. Then the plastic block is placed on a giant microtome which slices off sections as thin as 25 microns. After each slice, a motion picture camera automatically photographs the newly exposed brain surfaces remaining in the plastic block and, when these sections are shown in sequence, a dynamic picture of the brain structures results. As a further use of the technique, frames are projected onto sheets of paper where structures are traced by an electronic pen, thus transfering each point to a computer. From these points, the computer constructs the entire brain or individual brain surfaces, which appear as line drawings for display on a video screen. These drawings are then titled, rotated and tinted, illustrating in a highly effective manner the relationships of the major anatomical structures of the brain.
