Also, many people incorrectly argue that different parts of the brain control logic and emotion, due to the importance of the [https://www.sciencedirect.com/science/article/pii/S0028393211000285?via%3Dihub left] brain for language processing. Randall joins and spoofs these by suggesting that the right brain instead controls the upper torso. This would suggest that your left leg moves independently of your brain. To explain the areas of the body controlled by both halves of the brain, Randall declares those sections &quot;disputed,&quot; echoing a note added on maps that must display a border which is part of a {{w|territorial dispute}}. This suggests that the halves of your brain fight for control of the region, and is also described similarly to two countries disputing territory.<br /> <br /> ==Transcript==<br /> {{incomplete transcript|Do NOT delete this tag too soon.}}<br /> :[A stick figure with the right half of the figure's brain (on the viewer's left) colored orange and the left half (on the viewer's right) colored iris blue.
