Schizophrenia Markers Hidden in Brain-wide Signals - Anticevic Lab Publishes a Study Characterizing Global Signal in Schizophrenia

alt text 
A study reported online ahead of print by Yang et al. in the Proceedings of the National Academy of Sciences identified elevated global brain signal variability in schizophrenia, but not bipolar illness. This variability was re- lated to schizophrenia symptoms. A commonly used analytic procedure in neuroimaging, global signal regression, attenuated clinical effects and altered inferences. Furthermore, local voxel-wise variance was increased in schizophrenia, independent of global signal regression. Finally, neurobiologically grounded computational modeling suggests a putative mechanism, whereby altered overall connection strength in schizophrenia may underlie observed empirical results.

PsychiatryNews: Same Brain Circuits Linked With Psychosis in Two Disorders

alt text 
Anticevic Lab research featured on PsychiatryNews, reporting a new study recently published in Schizophrenia Bulletin titled "Ventral Anterior Cingulate Connectivity Distinguished Nonpsychotic Bipolar Illness from Psychotic Bipolar Disorder and Schizophrenia". The brains of schizophrenia patients and of those with bipolar disorder who experience psychotic episodes show similar connectivity patterns, which points to a common mechanism that may be associated with psychotic symptoms in the two disorders. “The findings reported here are striking and may be very important,” J. Raymond DePaulo Jr., M.D., a professor of psychiatry at Johns Hopkins University and a bipolar disorder expert said in an interview with Psychiatric News. “The findings are a step toward making functional sense of some of psychiatry’s diagnostic groupings and, if confirmed and extended, would contribute to the scientific substrate from which laboratory methods could be introduced into the psychiatric assessments of the future.”

Anticevic Lab publishes a theoretical review article on multi-disciplinary approaches to understand functional dysconnectivity in schizophrenia

Connectivity, pharmacology, and computation: toward a mechanistic understanding of neural system dysfunction in schizophrenia  

Anticevic Lab publishes a theoretical and review article in Frontiers in Psychiatry, detailing recent findings in functional connectivity in schizophrenia. The review specifically discusses two complementary approaches to better understand system-level alterations in schizophrenia. The first is pharmacological manipulations in healthy volunteers, which transiently mimic some cardinal features of psychiatric conditions. Second, the review discusses the combination of human pharmacological imaging with biophysically informed computational models developed to guide the interpretation of functional imaging studies and to inform the development of pathophysiologic hypotheses.

Anticevic Lab publishes a novel investigation characterizing amygdala functional connectivity across early course and chronic schizophrenia stages

A novel study by Anticevic Lab, in collaboration with Fei Wang, examines amygdala connectivity across distinct stages of schizophrenia. Specifically, the study focused on cross-sectionally comparing 1st episode schizophrenia patients with chronic patients and individuals at high risk of developing the illness. The principal finding suggests that amygdala coupling with bilateral orbitofrontal cortex is significantly reduced in all individuals with schizophrenia, irrespective of illness duration, but not in individuals at risk who have not gone on to develop frank psychosis. In contrast, high risk individuals exhibited elevated coupling between the amygdala and a brain stem region implicated in stress response.

Anticevic Lab, in collaboration with PittLab, publishes a data-driven investigation of brain-wide neural dysconnectivity in OCD

Anticevic Lab and PittLab characterize prefrontal and whole-brain connectivity via data-driven resting-state functional neuroimaging in obsessive-compulsive disorder. Results suggest prefrontal connectivity abnormalities with the rest of prefrontal cortex as well as whole-brain global alterations in connectivity. Specifically, subcortical structures showed aberrant increases in coupling with the rest of the brain, while prefrontal structures showed aberrant connectivity reductions, which predicted symptoms relevant to OCD. These findings implicate complex prefrontal connectivity alterations in the pathophysiology of OCD.

Multi-task connectivity reveals flexible hubs for adaptive task control

A study by Michael Cole and colleagues, in collaboration with Anticevic Lab, tested a novel hypothesis for how humans are able to implement highly adaptive behavior, such as rapidly learning new tasks from instructions. This hypothesis suggests select regions of the brain are 'flexible hubs' that coordinate brain networks to perform new tasks (e.g., orchestrating visual and motor information in a novel visuo-motor task).

Anticevic and colleagues characterize thalamo-cortical dysconnectivity in schizophrenia and bipolar illness

alt textThe image represents findings from Anticevic et al. (Cerebral Cortex) where authors characterized alterations in thalamo-cortical connectivity in one of the largest samples of schizophrenia patients in the literature. The authors discovered and then replicated robust alterations in thalamo-cortical systems whereby schizophrenia was associated with increased connectivity between the thalamus and all sensory-motor cortices. In contrast, schizophrenia was associated with reduced connectivity between the thalamus and higher-order cortical regions, the basal ganglia and the cerebellum. These effects represent one of the most robust markers of large-scale neural system alterations observed in schizophrenia. 

Yale Researchers Shed Light on Large-scale Thalamo-Cortical Disturbances in Schizophrenia and Bipolar Illness

Anticevic Lab along with a team of Yale researchers has used state-of-the-art non-invasive functional neuroimaging in one of the largest samples of patients diagnosed with schizophrenia and bipolar illness to better understand how large-scale neural communication may be altered in these severe and disabling psychiatric conditions. The results are reported online ahead of print in Cerebral Cortex. The Yale University press release can be found here.

Connectivity Study Focused on Prefrontal Cortex to Appear on Biological Psychiatry Cover

Anticevic and colleagues characterize global prefrontal and frontal-limbic connectivity using resting-state functional magnetic resonance imaging in bipolar disorder with and without psychosis history. The authors found evidence for medial prefrontal connectivity abnormalities with the rest of prefrontal cortex and the amygdala. Moreover, observed dysconnectivity predicted positive psychotic symptoms. These findings, using convergent resting-state techniques, implicate medial prefrontal cortex - a core emotion regulation region - in the pathophysiology of bipolar illness.

Anticevic Lab interviewed by Pittsburgh Post-Gazette

Mysteries of the Mind: Researchers take aim at schizophrenia's thinking problems

Some research suggests that people with [schizophrenia] have a particular network in their brains that is too noisy. Alan Anticevic, a research scientist at Yale University, said that the better people can suppress their default network, the more they can focus on a demanding task. While even some people without mental illness have trouble accomplishing this switch, those with schizophrenia seem to have a particularly difficult time, he said. Read more
