In patients undergoing brain surgery, stimulation of one parietal lobe area produced a feeling of wanting to move an upper limb, the lips, or the tongue (but without any actual movement). With increased stimulation, patients falsely believed they actually had moved. Curiously, when surgeons stimulated a different association area near the motor cortex in the frontal lobes, the patients did move but had no awareness of doing so * The underside of the temporal lobe If a stroke or head injury destroyed this area of your brain, you would still be able to describe facial features and to recognize someone’s gender and approximate age, yet be strangely unable to identify the person * neurogenesis, has been found in adult mice, birds, monkeys, and humans Master stem cells that can develop into any type of brain cell have also been discovered in the human embryo. Despite lists of lateralized functions, there are many areas of overlap and duplication in the hemispheres. This is part of the reason that the girl with only one hemisphere was able to adapt. If a blind person uses one finger to read Braille, the brain area dedicated to that finger expands as the sense of touch invades the visual cortex that normally helps people see * Click to reveal bullets. Brain scan studies show normal individuals engage their right brain when completing a perceptual task and their left brain when carrying out a linguistic task. However, many functions of the two hemispheres overlap. information from the left half of your field of vision goes to your right hemisphere, and information from the right half of your visual field goes to your left hemisphere, which usually controls speech. (Note, however, that each eye receives sensory information from both the right and left visual fields.) * No animation. I’ve included this here rather than later because it helps with understanding the split brain studies. Note (from the “Handedness” close-up box in the text): about 3 percent of people, mos
