Computer models and the brain.

Psychologists and computer enthusiasts have talked at length about the relationships between processing of information by the brain and processing of information by the computer. Models relating the two have been suggested, and attempts to draw analogies between the methods in which a computer would do a task and how the brain works have been frequent. Indeed, it has become popular to discuss brain functions in terms of computer terminology, and to project to the time when computers will duplicate brain processes. The present article discusses some of the difficulties and misassumptions which can arise from such discussions, and discusses those issues which must be addressed by those who wish to use the computer as a substitute for the brain.
