Removing Facial Features From Structural Mri Images Biases Visual Quality Assessment

Jonas Richiardi, Patric Hagmann, Elda Fischi Gomez, Thomas Sanchez, Oscar Esteban Rucavado Leandro

A critical step before data-sharing of human neuroimaging is removing facial features to protect individuals' privacy. However, not only does this process redact identifiable information about individuals, but it also removes non-identifiable information. ...

Structure-function coupling increases during interictal spikes in temporal lobe epilepsy: A graph signal processing study

Patric Hagmann, Dimitri Nestor Alice Van De Ville, Maria Giulia Preti

Objective: Structure-function coupling remains largely unknown in brain disorders. We studied this coupling during interictal epileptic discharges (IEDs), using graph signal processing in temporal lobe epilepsy (TLE). ...

A multi-scale probabilistic atlas of the human connectome

Meritxell Bach Cuadra, Patric Hagmann, Elena Najdenovska, Alessandra Griffa, Maxime Descoteaux

The human brain is a complex system that can be efficiently represented as a network of structural connectivity. Many imaging studies would benefit from such network information, which is not always available. In this work, we present a whole-brain multi-s ...

Simulated Half-Fourier Acquisitions Single-shot Turbo Spin Echo (HASTE) of the Fetal Brain: Application to Super-Resolution Reconstruction

Meritxell Bach Cuadra, Patric Hagmann, Reto Meuli, Sébastien Tourbier, Tobias Kober, Hamza Kebiri, Tom Hilbert, Thomas Yu

Accurate characterization of in utero human brain maturation is critical as it involves complex interconnected structural and functional processes that may influence health later in life. Magnetic resonance imaging is a powerful tool complementary to the u ...

The connectome spectrum as a canonical basis for a sparse representation of fast brain activity

Patric Hagmann, Gijs Plomp, David Pascucci

The functional organization of neural processes is constrained by the brain's intrinsic structural connectivity, i.e., the connectome. Here, we explore how structural connectivity can improve the representation of brain activity signals and their dynamics. ...

Fronto-Temporal Disconnection Within the Presence Hallucination Network in Psychotic Patients With Passivity Experiences

Patric Hagmann, Olaf Blanke, Alessandra Griffa, Pierre Progin, Giulio Rognini, Eva Blondiaux, Roy Salomon, Nathan Quentin Faivre, Jevita Potheegadoo, Giedre Stripeikyte, Kim Do

Psychosis, characterized by hallucinations and delusions, is a common feature of psychiatric disease, especially schizophrenia. One prominent theory posits that psychosis is driven by abnormal sensorimotor predictions leading to the misattribution of self- ...

Additive and interaction effects of working memory and motor sequence training on brain functional connectivity

Patric Hagmann, Alessandra Griffa

Although shared behavioral and neural mechanisms between working memory (WM) and motor sequence learning (MSL) have been suggested, the additive and interactive effects of training have not been studied. This study aimed at investigating changes in brain f ...

Sensorimotor Induction of Auditory Misattribution in Early Psychosis

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

Dysfunction of sensorimotor predictive processing is thought to underlie abnormalities in self-monitoring producing passivity symptoms in psychosis. Experimentally induced sensorimotor conflict can produce a failure in bodily self-monitoring (presence hall ...

Connectome spectral analysis to track EEG task dynamics on a subsecond scale

Patric Hagmann, Sébastien Tourbier, Gijs Plomp, Michaël Defferrard, David Pascucci

We present an approach for tracking fast spatiotemporal cortical dynamics in which we combine white matter connectivity data with source-projected electroencephalographic (EEG) data. We employ the mathematical framework of graph signal processing in order ...

A brief exposure to rightward prismatic adaptation changes resting-state network characteristics of the ventral attentional system

Patric Hagmann, Stephanie Clarke

A brief session of rightward prismatic adaptation (R-PA) has been shown to alleviate neglect symptoms in patients with right hemispheric damage, very likely by switching hemispheric dominance of the ventral attentional network (VAN) from the right to the l ...

Partial-volume modeling reveals reduced gray matter in specific thalamic nuclei early in the time course of psychosis and chronic schizophrenia

Meritxell Bach Cuadra, Patric Hagmann, Elena Najdenovska, Zita Rovó, Mario Joao Fartaria de Oliveira, Erick Jorge Canales Rodriguez, Kim Do

The structural complexity of the thalamus, due to its mixed composition of gray and white matter, make it challenging to disjoint and quantify each tissue contribution to the thalamic anatomy. This work promotes the use of partial-volume-based over probabi ...

Dynamic spatiotemporal patterns of brain connectivity reorganize across development

Patric Hagmann, Marie Schaer, Alessandra Griffa, Emeline Mullier

Late human development is characterized by the maturation of high-level functional processes, which rely on reshaping of white matter connections, as well as synaptic density. However, the relationship between the whole-brain dynamics and the underlying wh ...

N-Acetyl-Cysteine Supplementation Improves Functional Connectivity Within the Cingulate Cortex in Early Psychosis: A Pilot Study

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

Background: There is increasing evidence that redox dysregulation, which can lead to oxidative stress and eventually to impairment of oligodendrocytes and parvalbumin interneurons, may underlie brain connectivity alterations in schizophrenia. Accordingly, ...

Gradients of structure-function tethering across neocortex
