"Surely the rising star of body parts in the 1980 . . . Be right brain. Bookstores are well-stocked with guides to using the right brain in activities ranging from drawing business Techniques for brain training include talking with the telephone at the left ear, putting the right arm in a sting for a week, banning the use of the word 'no' and drawing the 'negative space' around the object instead of the object itself. Such exercises allegedly help us regain what some call 'wbole-brain thinking, ' especially those creative capacities ('R-modes') of the right hemisphere of the brain that have been neglected in favor of left-brain logic. . . . Anyone tempted to invest in R-modes will profit from Anne Harrington's enlightening history of the concept of the double brain. . . . Her book serves as a timely warning that the functions of the brain's hemispheres, like other kinds of division of labor, are likely to be far more complicated than the simple, seductive division into left and right can explain."---Elaine Showalter, New York Times Book Review
