26Mental abilities
Mental abilities are not absolutely separated into the left and right cerebral hemispheres of the brain. Some mental functions such as speech and language (e.g. Broca's area, Wernicke's area) tend to activate one hemisphere of the brain more than the other, in some kinds of tasks. If one hemisphere is damaged at an early age, these functions can often be recovered in part or even in full by the other hemisphere (see Neuroplasticity). Other abilities such as motor control, memory, and general reasoning are served equally by the two hemispheres.
27. Researcher Andrew Wakefield claimed a connection between vaccines and autism and autism spectrum disorders. Repeated attempts to reproduce the results by other researchers later showed that there is indeed no connection between the two and his research was ultimately shown to have been manipulated.
28. Rhinoceros horn in powdered form is not used as an aphrodisiac in traditional Chinese medicine as Cornu Rhinoceri Asiatici (犀角, xījiǎo, "rhinoceros horn"). It is prescribed for fevers and convulsions, a treatment not supported by evidence-based medicine.
29. In those with the common cold, the color of the sputum or nasal secretion may vary from clear to yellow to green and does not indicate the class of agent causing the infection.
30. Eating nuts, popcorn, or seeds does not increase the risk of diverticulitis. These foods may actually have a protective effect.

31Neuroregeneration
Despite long-standing belief that adult brains cannot generate any new neurons, neuroregeneration does occur. A 2013 study further showed that also in old age, about 700 new neurons are produced in the hippocampus daily.
32. Sugar does not cause hyperactivity in children. Double-blind trials have shown no difference in behavior between children given sugar-full or sugar-free diets, even in studies specifically looking at children with Attention deficit hyperactivity disorder or those considered sensitive to sugar.
