have developed specialized functions, the left side appearing to be better at some tasks, and the
right side better at others. The most obvious difference in functioning is that the left side of the
brain receives sensations from and controls the right side of the body and vice versa. The
reasons for this are still unclear. Despite a number of interesting theories, there is no obvious
advantage in such a cross over.
