Mapping Brain Tissue Loss in Adolescents with Schizophrenia. This map reveals the 3-dimensional profile of gray matter loss in the brains of teenagers with early-onset schizophrenia, with a region of greatest loss in the temporal and frontal brain regions that control memory, hearing, motor functions, and attention. Using novel image analysis algorithms, dramatic reductions in the profiles of gray matter were detected, based on a database of 96 images from schizophrenic patients scanned repeatedly with MRI. The parallel extraction of anatomical models from all patients in the image database required 60 CPU hours, when running in parallel on an SGI RealityMonster with 32 internal CPUs.

World Health Organization definition:

Schizophrenia – The schizophrenic disorders are characterized in general by fundamental and characteristic distortions of thinking and perception, and affects that are inappropriate or blunted. Clear consciousness and intellectual capacity are usually maintained although certain cognitive deficits may evolve in the course of time. The most important psychopathological phenomena include thought echo; thought insertion or withdrawal; thought broadcasting; delusional perception and delusions of control; influence or passivity; hallucinatory voices commenting or discussing the patient in the third person; thought disorders and negative symptoms.
