Q

Criticisms

A

Reductionist. Too simplistic to explain a complex disorder by looking at one part of the brain

Ignores nurture. The brain still needs to interact with what is happening in the environment to be able to produce symptoms like hallucinations

Too deterministic. Schizophrenia might not be completely controlled by what is happening in the brain. Some people may let their symptoms to take over rather than trying to mentally control them.
