| Research Abstract |
NK-1 receptors in the human brain were visualized and quantified using ^<18>F-FE-SPA-RQ with PET. The prefrontal and the limbic cortices, the regions responsible for the depression and the anxiety disorders, expressed substantial amount of NK-1 receptors. An fMRI study revealed neural substrates influenced by an antidepressant during the cognitive task performance. The combined application of both noninvasive neuroimaging techniques could be of great utility for development and evaluation of drugs to treat psychiatric disorders.
