“The normal brain learns from what it perceives. It doesn’t have to start from zero if it hears the same thing twice. People with schizophrenia, however, couldn’t manage that. In test after test, conducted at Freedman’s lab in Denver, their brains showed two waves of equal size for the two clicks. It was as if they had to react all over again to the second click – even though they had just heard the same click a fraction of a second earlier.”
