Burke, et al. (2014) conducted a study involving 10 women with conversion disorder. the findings revealed that when the anesthetic body part was stimulated, there was decreased activation in somatosensory cortex but increased activation in areas such as the anterior cingulate cortex and the insula. these results support the notion that

sensory areas of the brain may be inhibited by overactive emotion-based processing areas of the brain.

Explanation:

If a person faces symptoms such as blindness, paralysis or any other neurologic symptoms that cannot be explained by any medical diagnosis then such a person is said to be suffering from a mental condition known as conversion disorder. This disorder is caused by psychological problems that a person usually experiences after having a stressful experience in life. There have been several notions that have been proposed to explain the cause of the disorder and one such notion is given by the study conducted by Burke et. al. wherein it has been proposed that if an area of the brain is dealing with overactive emotions then other areas of the brain (cognitive) can be turned off.
