Chapter 46, Problem 14TYPSS
Summary Introduction
To review:
The pros and cons of lesion studies and electrical stimulation of conscious patients to study the functions of different part of brain.
Introduction:
Lesion studies and electrical stimulation are used for the mapping studies of cerebrum. The earlier work to determine the brain function was based on the studies on people with specific mental deficits caused by areas of brain damage, or lesions. In 1861 Paul Brocastudied an individual who could not speak but could understand thelanguage. The studies discovered the damaged area or lesion present in the left frontal lobe of the cerebrum. Broca concluded that this region of brain is responsible for the speech. Likewise the electrical stimulation of the patients in awakened condition and under a local anesthetic, helps to map essential areas of brain.

A negligence action was brought by a mother against a hospital on behalf of her minor daughter. It alleged that when the mother was 13 years of age, the hospital negligently transfused her with Rh-positive blood. The mother's Rh-negative blood was incompatible with and sensitized by the Rh-positive blood. The mother discovered her condition 8 years later during a routine blood screening ordered by her healthcare provider in the course of prenatal care. The resulting sensitization of the mother's blood allegedly caused damage to the fetus, resulting in physical defects and premature birth.
Did a patient relationship with the transfusing hospital exist?
