About this Research Topic
Neuroimaging studies have provided a significant contribution to the identification of wide-spread neural abnormalities in patients with a variety of psychiatric disorders. Although each disorder is characterized by anomalies in distinct networks, many share frontal dysfunction. But the frontal cortex clearly is not one entity and consists of many distinct areas that have different anatomy, connectivity and function. A better understanding of differences and similarities in frontal dysfunctioning is necessary to identify the shared and divergent neural mechanisms that underlie these disorders. Therefore, the aim of this Research Topic is to juxtapose frontal abnormalities in patients with various psychiatric disorders. We welcome contributions that asses frontal structure or function using a wide variety of neuroimaging techniques, such as electrophysiological (EEG, MEG), neuroimaging (MRI, PET), and neurostimulation methods (TMS, DCS). The contributions are not limited to particular disorders, and may include patients with addiction, anxiety, attention, autistic, mood, personality, or psychotic disorders. Contributions that directly compare disorders, as well as studies that investigate frontal functions that are typically investigated in other disorders are highly appreciated. Discussion of the results with respect to findings in other disorders is encouraged. Reviews and opinions discussing frontal abnormalities across disorders are also of particular interest. We anticipate that this Research Topic will provide further insight into the common and specific neural mechanisms of psychiatric disorders.
