Question

Quizplus · Accepted Answer

The brain is a self-organizing system, which means that it can change its own structure and function in response to experience. This makes it difficult to predict the psychological phenotype from the genotype, because the genotype only provides a starting point for the development of the brain. The actual structure and function of the brain will be shaped by the individual's experiences, which can vary widely.
