Público ISBD [artículo]  inThe American Journal of Psychiatry > Año 2019 - Vol. 176 - No.7 (Julio) . - pp. 507-511 Título : A Reckoning and Research Agenda for Neuroimaging in Psychiatry Tipo de documento: texto impreso Autores: Amit Etkin, Autor Fecha de publicación: 2019 Artículo en la página: pp. 507-511 Idioma : Inglés (eng) Idioma original : Inglés (eng) Palabras clave: Neuroimagen, psicopatología. Resumen: Human neuroimaging has been a core component of both research in psychiatry and conceptual models of the brain circuit-level mechanisms underlying psychopathology. Despite landmark neuroimaging research over the past 25 years, we still lack the level of precision and insight needed for bringing neuroimaging tools into clinical care contexts.

Cerebellar-Prefrontal Network Connectivity and Negative Symptoms in Schizophrenia / Roscoe O. Brady en The American Journal of Psychiatry, Año 2019 - Vol. 176 - No.7 (Julio)

Público ISBD [artículo]  inThe American Journal of Psychiatry > Año 2019 - Vol. 176 - No.7 (Julio) . - pp. 512-520 Título : Cerebellar-Prefrontal Network Connectivity and Negative Symptoms in Schizophrenia Tipo de documento: texto impreso Autores: Roscoe O. Brady, Autor ; Irene Gonsalvez, Autor ; Ivy Lee, Autor Fecha de publicación: 2019 Artículo en la página: pp. 512-520 Idioma : Inglés (eng) Idioma original : Inglés (eng) Palabras clave: Técnicas de imagenología cerebral, Esquizofrenia Resumen: The interpretability of results in psychiatric neuroimaging is significantly limited by an overreliance on correlational relationships. Purely correlational studies cannot alone determine whether behavior-imaging relationships are causal to illness, functionally compensatory processes, or purely epiphenomena.

To identify biologically and/or behaviorally driven as opposed to diagnostically driven subgroups of individuals, the authors used hierarchical clustering to identify individuals with similar patterns of brain activity during a facial imitate/observe functional MRI task.

Wannan, Autor ; Vanessa L. Cropley, Autor ; Mallar Chakravarty, Autor Fecha de publicación: 2019 Artículo en la página: pp. 552-563 Idioma : Inglés (eng) Idioma original : Inglés (eng) Palabras clave: Neuroimagen estructural, Esquizofrenia, Conectividad cerebral, Covarianza estructural, Espesor cortical, Red. Resumen: Cortical thickness reductions in schizophrenia are irregularly distributed across multiple loci. The authors hypothesized that cortical connectivity networks would explain the distribution of cortical thickness reductions across the cortex, and, specifically, that cortico-cortical connectivity between loci with these reductions would be exceptionally strong and form an interconnected network.
