Researchers have discovered that the brain volume of individuals with schizophrenia is less than normal. This decrease in brain volume is accompanied a corresponding
A) decrease in the size of the ventricles.
B) increase in the size of the ventricles.
C) decrease in the size of the skull.
D) increase in the size of the skull.
Answer: B
Rationale: The volume of the entire brain is reduced by approximately 2% in those individuals with schizophrenia—a small but significant difference. This decrease in brain tissue corresponds with an increase in the size of the brain ventricles, the fluid-filled spaces occurring within the core of the brain.
