After Williams' discovery, other biologists ransacked nature looking for the presence of the juvenile hormone in other species. Last year Drs. Lawrence I. Gilbert and Howard A. Schneiderman of Cornell University extracted a substance from the cortex of the adrenal glands of cattle. They found it had the same effect on silkworm pupae as the moth hormone. For the first time a hormone extracted from vertebrates was shown to influence the growth of invertebrate insects...
...through the areas that control speech and the movement of the right side of the body. It had also cut some of the white fibers leading from the retinas of both eyes to the visual center in the back of the brain, and other fibers leading from the frontal cortex (associated with intellectual and reasoning functions) to other parts of the brain. George Congrave, 21, a chemical engineering student from Edson, Alberta, seemed likely to spend the rest of his life more like a vegetable than...
There was little hope that Congrave would ever regain the use of the right side of his body. How severe and lasting the impairment of his vision would be could not yet be told, or the extent to which other fibers to the frontal and temporal areas of the cortex would take over the functions of those destroyed. The acid test of Congrave's recovery would be months hence, when a member of the chemical engineering faculty brings down his textbooks to see how much he has retained, how much more he can learn...
Interpretive Cortex. Dr. Penfield is confident that the temporal lobe areas he has studied are only transmission belts for the electrical impulses that pass through the brain at the time of the original experiences, and that the actual storehouse of the impressions is in a deeper part of the brain. His electric needling sends an impulse to this storehouse that revives the experience. But it does something more: he finds that often, when his patients are stimulated, they have a "feeling about the present situation-an interpretation of the present, but not one that the patient thinks out deliberately...
...temporal lobe are like a process that is common in everyday life: a flashback of past experience, and an almost instantaneous comparison of the present with previous similar experiences. For this area of the brain, to which no function had been assigned, he proposes the term "interpretive cortex." Its discovery, he suggests, is a step toward explaining what Hippocrates called the brain's power to "distinguish the ugly from the beautiful, the bad from the good, the pleasant from the unpleasant...
