As an added benefit, the preserved samples also come with detailed clinical notes, which can help modern researchers make post-mortem diagnoses. And perhaps most usefully, the brains have not been altered by modern medicines, offering an untainted view of the physiology of a schizophrenic mind. Extracting DNA and RNA from these jellied brains has proven difficult, however, although researchers were able to extract DNA after the samples were stored in liquid nitrogen. The work has not yet been peer-reviewed or published, but if the DNA extraction methods are validated, it could yield a new database of brain information.
