Answer to Question 1

Answer: OCD has been treated using limited damage to the cingulum bundles, which connect the prefrontal and cingulate cortexes with the temporal lobe limbic cortex. The cingulotomy procedure offers a change of improvement for patients, is not associated with personality changes, and is a procedure of last resort, after drug therapies have been tried and failed.

Answer to Question 2

Answer: Epidemiological studies show that season of birth can increase the risk of developing schizophrenia, with greater risk apparent for children born during the later winterthis may reflect the occurrence of a viral illness during the second trimester of prenatal development. Identical twins who share the same placenta (monochorionic) are more likely to develop schizophrenia than are dichorionic identical twins. A mutation of the DISC-1 gene may result in abnormalities of the prefrontal cortex that in turn results in schizophrenia.
