Description
Schizophrenia is a mental disorder often characterized by abnormal social behavior and failure to recognize what is real. Common symptoms include false beliefs, unclear or confused thinking, auditory hallucinations, reduced social engagement and emotional expression, and inactivity. Maps of the average annual rates of brain surface contraction in (a) individuals at ultra-high risk for developing psychosis who converted to psychosis (converters) versus those who did not convert (nonconverters), and (b) schizophrenia patients versus healthy controls. Converters and schizophrenia patients showed significantly greater brain-contraction rates compared with nonconverters and healthy individuals, respectively. A similar pattern of prominent prefrontal surface contraction was shared across groups. For the top two rows, bluer areas indicate regions of higher surface motion, while red and pink areas indicate areas of negative motion, or contraction; in the bottom row, red indicates regions that show statistically significant differences in the rate of contraction between groups. Based on data in Sun, Stuart, Phillips, et al. (2009) and Sun, Stuart, Jenkinson, et al. (2009). MRI (magnetic resonance imaging) is a diagnostic technique used to create images of the body like a CT. It is non-invasive (It does not enter the body cavity) and requires no radiation, instead it is based on the magnetic fields of the hydrogen atoms in the 3D Magnetic Resonance Imaging (3D MRI) body. By scanning the body, MRI is able to provide computer-generated images of the body's internal tissues and organs. MRI usually scans the body in an axial plane (ie. cutting the body into slices from front to back). Usually the images are 2 dimensional, where the MRI images are usually presented in slices from top to bottom. However, using sophisticated computer calculation, these 2 dimensional slices can be joined together to produce a 3 dimensional model of the area of interest being scanned. This is called 3
