About this Research Topic
Last year we edited a Frontiers Research Topic on “An update on neurocognitive impairment in schizophrenia and depression”. We are now following-up this initiative with a new invitation, focusing on “Cognition and neuroimaging in schizophrenia”, thus narrowing the focus on schizophrenia, but expanding the focus to functional and structural neuroimaging to reveal the underlying neuronal architecture behind cognitive impairments. A second focus is closing in on auditory hallucinations and "hearing voices" in the general population by non-psychotic individuals. This has become an important topic in research on schizophrenia and could cast new light on commonalities in symptom-like behavior in non-clinical and clinical “voice hearers” and hallucinating individuals, that in turn could say something about a continuum of symptoms. A third focus is on network connectivity and connectome mapping in schizophrenia using novel state-of-the-art neuroimaging analysis tools. Schizophrenia has long been considered a disease of disconnectivity and thus special emphasis is given to work which addresses the schizophrenia macro-connectome including both functional and structural aspects. Central to such an approach are recent discoveries of intrinsic resting state networks that are task independent, and/or activated in the absence of a cognitive task. Possible impairments in the dynamic interactions between large-scale networks may prove new insights into the neurobiology of schizophrenia and schizophrenia symptoms.
