Simply recognizing that you have a funny feeling isn’t very helpful if your objective is to make intelligent decisions. With a little self-examination you should be able to identify not just that you have a hunch, but what that hunch is. If, for example, a woman has an uncomfortable feeling when she leaves an interview [...]
Definitions and Criteria for Stem Cells
Stem cells have the capacity to self-renew and generate differentiated cells. Self-renewal is defined as the ability to generate daughter cells identical to their mother. The daughter can also produce progeny with more restricted potential. Thus, a stem cell can divide to generate one daughter cell that is a stem cell and another daughter cell [...]
Lasers in Neurosurgery
Neurosurgery deals with diseases of the central nervous system (CNS), i.e. the brain and the spine. Surgery of brain tumors is very difficult, since extremely localized operations are necessary due to the complicated structure and fragility of the brain. Moreover, the tumor itself is often not easily accessible, and very important vital centers are situated [...]

They also have an increased risk of suicide. Manic depression afects 1.2 percent of Americans age 18 or older annually, or 2.2 million individuals. Approximately equal numbers of [...]

The Expression of Emotion at Work

Work, particularly when commercially driven, was seen as being ‘rational’, not ‘emotional’, it also being seen as unprofessional to be otherwise. This, of course, was why women were seen to be less adequate in the workplace than men; they [...]
Scholastic Aptitude Tests
In the 1920s objective examinations, based loosely on the Army Alpha test, began to be used in addition to high school grades for the purpose of making admissions decisions in colleges and universities. This momentous development, which culminated in the creation of the Scholastic Aptitude Test (SAT) in 1926, foreshadowed the arrival of many more [...]
What Is a Commissurotomy?
Commissurotomy is the surgical cutting of the cerebral commissures as an elective treatment for epilepsy. Surgeons Philip Vogel and Joseph Bogen at the White Memorial Medical Center in Los Angeles reintroduced this technique, and the results obtained by Sperry and his coworkers with their “split brain” patients are now well known . As a result [...]
