Delayed- Maturation Theory of Obsessive Compulsive Disorder have OCD and to measure specific structure's neural activity. The MRI scanning techniques have identified smaller levels of white matter volume in women with OCD in comparison to control patients that do not have OCD. The use of positron emission tomographic scan, better known as the PET scan, has enabled researchers to observe structures of the OFC, anterior cingular cortex, and the striatum for evidence of abnormal neural activity. In relationship to delayed-maturation theory of obsessive compulsive disorder, PET scans have consistently observed the caudate nucleus, cingulate volume, and volumes of both gray matter and white matter to be less
