| β | + | As a general rule, each cerebral hemisphere controls the opposite side of the body. So things on the left half of the body are controlled by the right side of the brain and vice-versa. However, this is simply a rough approximation. Biology is complicated, and as with most biology "rules" there are exceptions, such as the {{w|cranial nerves}}. | |
| β | + | While the motor and sensation aspects of nerve innervation have been relatively well-established from studies, experiments, and dissections, there is always going to be an exception. Any number of factors may cause deviation from the normal physiology: trauma, disease, congenital birth defects, brain plasticity, etc. | |
| + | |||
| + | With less concrete aspects of human brain function, such as logic, emotion, language processing, and creativity, establishing which brain hemisphere has control is more complicated, and again, while studies have established which hemisphere is more likely to be involved with which function, these generalizations are not necessarily true for every individual. | ||
| + | |||
| + | [[Randall]] spoofs this by saying that the right brain controls the upper torso, while the left brain controls the right side, and your left leg moves independently of your brain. Randall declares the upper right side of the body "disputed," echoing maps that display a {{w|territorial dispute}}, suggesting that the halves of your brain fight for control of the region. Alternatively, he states there would be {{w|Dual control}} like in an airplane, where the pilot and the copilot both can control the plane at any time. This spoof hypothesis might be an attempt to explain why most people are more skilled with their hands than their feet and with their right side than their left. | ||
| + | |||
| + | The title text further confuses this division, by stating the left hand is on the right arm and presumably vice-versa. This would cause further problems, as a hemisphere could end up controlling an arm and the hand on the other arm, and these problems are made worse if this also applies to the feet. | ||

:[Cueball is shown with the right half of his brain (on the viewer's left) colored in orange and the left half (on the viewer's right) in iris blue. An iris blue box is overlaid over the right half of the body (on the viewer's left), and an orange box is overlaid over the top half. The boxes are overlapping in a greenish color on the upper right quarter of the body (on the viewer's left).] | :[Cueball is shown with the right half of his brain (on the viewer's left) colored in orange and the left half (on the viewer's right) in iris blue.
