Dysmaturation Observed as Altered Hippocampal Functional Connectivity at Rest Is Associated With the Emergence of Positive Psychotic Symptoms in Patients With 22q11 Deletion Syndrome
Dimitri Nestor Alice Van De Ville, Maude Schneider, Farnaz Delavari, Daniela Maria Zöller, Karin Bortolin
BACKGROUND: Hippocampal alterations are among the most replicated neuroimaging findings across the psychosis spectrum. Moreover, there is strong translational evidence that preserving the maturation of hippocampal networks in mice models prevents the progr ...
ELSEVIER SCIENCE INC2021Altered anterior default mode network dynamics in progressive multiple sclerosis
Dimitri Nestor Alice Van De Ville, Maria Giulia Preti, Giulia Bommarito, Anjali Bagunu Tarun, Younes Farouj
Background: Modifications in brain function remain relatively unexplored in progressive multiple sclerosis (PMS), despite their potential to provide new insights into the pathophysiology of the disease at this stage. Objectives: To characterize the dynamic ...
SAGE PUBLICATIONS LTD2021Abnormal Development and Dysconnectivity of Distinct Thalamic Nuclei in Patients With 22q11.2 Deletion Syndrome Experiencing Auditory Hallucinations
BACKGROUND: Several studies in patients with schizophrenia have demonstrated an abnormal thalamic volume and thalamocortical connectivity. Specifically, hyperconnectivity with somatosensory areas has been related to the presence of auditory hallucinations ...
ELSEVIER2020A computational biophysical model of thalamic and reticular nucleus microcircuitry: from neurons to emergent network dynamics
The thalamus, once believed to be a simple relay station between the body periphery and the neocortex, has started to be recognized as a key player in higher-order functions, such as attention. It participates in the transition between brain states, such a ...
EPFL2020Anatomically and functionally distinct thalamocortical inputs to primary and secondary mouse whisker somatosensory cortices
Carl Petersen, Georgios Foustoukos, Sami El-Boustani, Berat Semihcan Sermet
Subdivisions of mouse whisker somatosensory thalamus project to cortex in a region-specific and layer-specific manner. However, a clear anatomical dissection of these pathways and their functional properties during whisker sensation is lacking. Here, we us ...
NATURE PUBLISHING GROUP2020Hallucination Engineering: From Neuroscience Robotics to Hallucinations in Health and Disease
My thesis focuses on a psychotic symptom called the presence hallucination (PH). PHs are defined as the false perception that someone is nearby when no one is actually present. PHs can occur in various populations, ranging from healthy subjects (when expos ...
EPFL2020Improved susceptibility-weighted imaging for high contrast and resolution thalamic nuclei mapping at 7T
Meritxell Bach Cuadra, Constantin Tuleasca, José Pedro Rebelo Ferreira Marques, Daniel Gallichan, João Pedro Forjaco Jorge, Elena Najdenovska, Frédéric Gretsch
Purpose The thalamus is an important brain structure and neurosurgical target, but its constituting nuclei are challenging to image non-invasively. Recently, susceptibility-weighted imaging (SWI) at ultra-high field has shown promising capabilities for tha ...
2020Partial-volume modeling reveals reduced gray matter in specific thalamic nuclei early in the time course of psychosis and chronic schizophrenia
Meritxell Bach Cuadra, Erick Jorge Canales Rodriguez, Patric Hagmann, Kim Do, Mario Joao Fartaria de Oliveira, Elena Najdenovska, Zita Rovó
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 ...
WILEY2020Increased Neural Strength and Reliability to Audiovisual Stimuli at the Boundary of Peripersonal Space
The actionable space surrounding the body, referred to as peripersonal space (PPS), has been the subject of significant interest of late within the broader framework of embodied cognition. Neurophysiological and neuroimaging studies have shown the represen ...
2019Large-Scale Brain Network Dynamics Provide a Measure of Psychosis and Anxiety in 22q11.2 Deletion Syndrome Daniela
Dimitri Nestor Alice Van De Ville, Marie Schaer, Fikret Isik Karahanoglu, Maria Carmela Padula
BACKGROUND: Prodromal positive psychotic symptoms and anxiety are two strong risk factors for schizophrenia in 22q11.2 deletion syndrome (22q11DS). The analysis of large-scale brain network dynamics during rest is promising to investigate aberrant brain fu ...
