The Focus on Neuroscience box "Schizophrenia: A Wildfire in the Brain," discussed research by neuroscientist Paul Thompson on brain development in adolescence. Which of the following is a key finding from that research?

A) The decrease in the size of the ventricles was directly correlated with the severity of hallucinations and delusions in the schizophrenic adolescents.
B) The increase in the amount of gray matter tissue was directly correlated with the severity of cognitive deficits experienced.
