Functional Disconnection Within The Presence Hallucination Network In Psychotic Patients With First-Rank Symptoms

Patric Hagmann, Olaf Blanke, Pierre Progin, Giulio Rognini, Nathan Quentin Faivre, Jevita Potheegadoo, Giedre Stripeikyte, Kim Do

OXFORD UNIV PRESS2019

Sensorimotor Induction of Auditory Misattribution in Psychosis is Linked to Neural Disconnectivity

Patric Hagmann, Olaf Blanke, Alessandra Griffa, Pierre Progin, Giulio Rognini, Silvia Marchesotti, Roy Salomon, Andrea Serino, Kim Do

Background: Schneiderian first rank symptoms (FRS) are characterized by a diminished demarcation of self-other boundaries, causing misattribution of self-generated thoughts and actions to external sources. We have shown that introducing sensorimotor predic ...

N-acetylcysteine add-on treatment leads to an improvement of fornix white matter integrity in early psychosis: a double-blind randomized placebo-controlled trial

Patric Hagmann, Rolf Gruetter, Lijing Xin, Alessandra Griffa, Kim Do

Mechanism-based treatments for schizophrenia are needed, and increasing evidence suggests that oxidative stress may be a target. Previous research has shown that N-acetylcysteine (NAC), an antioxidant and glutathione (GSH) precursor almost devoid of side e ...

Network-Based Asymmetry of the Human Auditory System

Patric Hagmann, Alessandra Griffa, Olaf Sporns

Improving clinico-radiological correlation in multiple sclerosis with automated tract and topology annotations

Jonas Richiardi, Patric Hagmann, Reto Meuli, Tobias Kober, Caterina Bigoni, Mario Joao Fartaria de Oliveira

SAGE PUBLICATIONS LTD2018

Redox dysregulation as a link between childhood trauma and psychopathological and neurocognitive profile in patients with early psychosis

Patric Hagmann, Alessandra Griffa, Kim Do

Exposure to childhood trauma (CT) increases the risk for psychosis and affects the development of brain structures, possibly through oxidative stress. As oxidative stress is also linked to psychosis, it may interact with CT, leading to a more severe clinic ...

Holographic Visualisation and Interaction of Fused CT, PET and MRI Volumetric Medical Imaging Data Using Dedicated Remote GPGPU Ray Casting

Adrien Raphaël Depeursinge, Patric Hagmann, Stéphane Gobron

Medical experts commonly use imaging including Computed Tomography (CT), Positron-Emission Tomography (PET) and Magnetic Resonance Imaging (MRI) for diagnosis or to plan a surgery. These scans give a highly detailed representation of the patient anatomy, b ...

Redox Dysregulation, Oligodendrocytes And White Matter Alterations In Schizophrenia

Patric Hagmann, Lijing Xin, Alessandra Griffa, Kim Do

Oxford University Press2018

Childhood Trauma Engages Oxidative Stress, Hippocampus Alterations, And Poorer Clinical Outcome In Early Psychosis Patients

Patric Hagmann, Alessandra Griffa, Kim Do

In-vivo probabilistic atlas of human thalamic nuclei based on diffusion-weighted magnetic resonance imaging

Jean-Philippe Thiran, Meritxell Bach Cuadra, Patric Hagmann, Elena Najdenovska, Maxime Descoteaux

The thalamic nuclei are involved in many neurodegenerative diseases and therefore, their identification is of key importance in numerous clinical treatments. Automated segmentation of thalamic subparts is currently achieved by exploring diffusion-weighted ...

Decreased integration and information capacity in stroke measured by whole brain models of resting state activity

Patric Hagmann, Alessandra Griffa

While several studies have shown that focal lesions affect the communication between structurally normal regions of the brain, and that these changes may correlate with behavioural deficits, their impact on brain's information processing capacity is curren ...

Transient networks of spatio-temporal connectivity map communication pathways in brain functional systems

Jean-Philippe Thiran, Pierre Vandergheynst, Xavier Bresson, Patric Hagmann, Alessandra Griffa, Alessandro Daducci, Kirell Maël Benzi, Benjamin Ricaud

The study of brain dynamics enables us to characterize the time-varying functional connectivity among distinct neural groups. However, current methods suffer from the absence of structural connectivity information. We propose to integrate infra-slow neural ...

Exploring the role of white matter connectivity in cortex maturation

Patric Hagmann, Alessandra Griffa, Petra Susan Hüppi

The maturation of the cortical gray matter (GM) and white matter (WM) are described as sequential processes following multiple, but distinct rules. However, neither the mechanisms driving brain maturation processes, nor the relationship between GM and WM m ...

An affected core drives network integration deficits of the structural connectome in 22q11.2 deletion syndrome

Patric Hagmann, Marie Schaer, Alessandra Griffa, Frantisek Vasa

Chromosome 22q11.2 deletion syndrome (22q11DS) is a genetic disease known to lead to cerebral structural alterations, which we study using the framework of the macroscopic white-matter connectome. We create weighted connectomes of 44 patients with 22q11DS ...

Elsevier Sci Ltd2016

Characterizing the connectome in schizophrenia with diffusion spectrum imaging

Jean-Philippe Thiran, Patric Hagmann, Alessandra Griffa, Kim Do

Schizophrenia is a complex psychiatric disorder characterized by disabling symptoms and cognitive deficit. Recent neuroimaging findings suggest that large parts of the brain are affected by the disease, and that the capacity of functional integration betwe ...

Resting-State Temporal Synchronization Networks Emerge from Connectivity Topology and Heterogeneity

Patric Hagmann

Spatial patterns of coherent activity across different brain areas have been identified during the resting-state fluctuations of the brain. However, recent studies indicate that resting-state activity is not stationary, but shows complex temporal dynamics. ...

Glutathione deficit impairs myelin maturation: relevance for white matter integrity in schizophrenia patients

Jean-Philippe Thiran, Patric Hagmann, Philipp Baumann, Rolf Gruetter, Lijing Xin, Alessandra Griffa, Aline Monin, Kim Do

Schizophrenia pathophysiology implies both abnormal redox control and dysconnectivity of the prefrontal cortex, partly related to oligodendrocyte and myelin impairments. As oligodendrocytes are highly vulnerable to altered redox state, we investigated the ...
