Organization of the human brain
Article Abstract:
The brain appears to be structurally and functionally organized into units which interact to produce various mental activities. Structure-function relationships of the brain were studied in patients with epilepsy, where the two halves of the brain had been surgically separated to control the epilepsy. These patients had no perceptual (visual) or cognitive (thinking) transfer of information between the two sides of the brain. In a patient where the posterior portion of the brain was separated, transfer of visual information occurred between the two sides of the brain, but there was no transfer of audio (hearing) or tactile (feeling) information. Other studies suggested that language processes involve the connection of the anterior regions with the frontal areas of the brain. Specific functions of the various areas of the brain were studied in patients with brain damage to certain areas. The right side of the brain contains limited language skills. Words and grammar are known but comprehension is limited. The right side of the brain is involved in face recognition. The left brain was shown to be involved in the interpretation of data and the interpretation of emotions produced in the right side, such as changes in moods. Although certain skills are located in precise areas of the brain, the interaction of these areas results in the functional and cogitative capacity of an individual.

Educating the public - and health workers about "brain attacks." (stroke victims require prompt treatment)(Cardiovascular Medicine)
Article Abstract:
Because new drugs that can prevent serious damage from stroke must be administered within hours after the stroke, the public and health care workers must be re-educated to treat stroke as an emergency. Before the drugs, hours often passed before stoke victims received medical attention.

Building an associative memory vastly larger than the brain
Article Abstract:
It is possible to use the DNA computer proposed by Leonard Adleman and the biological computational procedures described by Richard Lipton to build a large associative memory that would be content addressable.
