Neuroimaging of Serotonin System in Anxiety Disorders

A large body of research including animal and human studies has confirmed the crucial role of the serotonin (5-HT) system in the regulation of anxiety-related behaviour and traits. In the past decade, the functional status of the 5-HT system in anxiety disorders has been regularly investigated by novel neuroimaging techniques, such as single-photon emission computed tomography (SPECT) and positron emission tomography (PET). Although these...
