The video starts with a close-up shot of a human brain. The brain is yellowish in color and has a wrinkled texture. As the video progresses, a metal drill bit appears from the right side of the frame and begins to drill into the brain. The drill bit is silver and has a spiral design. The drilling action is steady and precise, and the drill bit penetrates deeper into the brain with each subsequent frame. The video ends with the drill bit fully inserted into the brain.
