BRUCE LERRO—Faust is seen by many as the best representative of modern self-consciousness who declared there were two souls in his breast. The right side of the brain deals with the big picture and emerges first in human development. Its attention is diffused and it searches for unique patterns in the real world. Whatever information it finds, it places it in a context. For the brain’s right side, wholes are more than the sum of their parts. Once the new information is in, its function is to stabilize the system (negative feedback). The right hemisphere watches out not only for itself but for the left side as well. It multitasks. In the brain, the right-side does parallel processing of systems at the same time. It generates alternatives to problems.
The left hemisphere is its junior partner and is more unpredictable. The left hemisphere is more specialized, focused and sees the parts very well in isolation. The left hemisphere does not seek out new information but focuses on bringing order and logic within the system.
