A 5 yr old girl is reported with patchy white matter lesions, cystic degeneration of the temporal tips, normal cortex, and normal cerebellum, documented by FLAIR, and diffusion-weighted MRI.
On the other hand, the MRI images of women with normal libido showed activity in the entorhinal cortex, an area of the brain where positive emotions are registered.
The study results could help distinguish between normal and abnormal processes within the visual cortex and identify what parts of the brain are targets for the treatment of anxiety disorders.
One of the reasons for this, as demonstrated in a recent paper by researchers at Yale medical school, is that when a person experiences extreme stress, or just goes through the normal process of aging, the prefrontal cortex accumulates cyclic-AMP.
