Mistakes/Goofs

• Goof (errors made by characters, possibly deliberate errors by the filmmakers): Dr. Rosen incorrectly explains "proprioception", implying that it's a kind of psychic sense that alerts people when someone else is watching them. In reality, proprioception refers to any sense located entirely within the body (rather than originating externally, like vision and hearing); in particular, the sense of where parts of the body are located relative to each other (such as whether an arm is flexed or extended, or to the left or the right). Occasionally, as a result of brain damage, people lose their sense of proprioception, which makes everyday tasks like walking and eating very difficult. People without proprioception can only walk by carefully watching the positions of their legs, since they can't feel whether their feet are on the ground or off.

Trivia

• Brent Spiner's character in this episode had no optic nerve, just like LeVar Burton's character of Geordi LaForge in Star Trek: The Next Generation.
