Effective connectivity in brain networks estimated using EEG signals is altered in children with ADHD

Amir Hossein Omidvarnia

This study presents a methodology developed for estimating effective connectivity in brain networks (BNs) using multichannel scalp EEG recordings. The methodology uses transfer entropy as an information transfer measure to detect pair-wise directed informa ...

Remodeling of brain morphology in temporal lobe epilepsy

Bogdan Draganski, Lester Melie Garcia

Background Mesial temporal lobe epilepsy (TLE) is one of the most widespread neurological network disorders. Computational anatomy MRI studies demonstrate a robust pattern of cortical volume loss. Most statistical analyses provide information about localiz ...

Nucleus accumbens neurochemistry in human anxiety: A 7 T 1H-MRS study

Rolf Gruetter, Alina Veronika Irene Strasser, Maria del Carmen Sandi Perez, Lijing Xin

Individual differences in anxiety provide a differential predisposition to develop neuropsychiatric disorders. The neurochemical underpinnings of anxiety remain elusive, particularly in deep structures, such as the nucleus accumbens (NAc) whose involvement ...

Depersonalization- and derealization-like phenomena of epileptic origin

Olaf Blanke, Lukas Heydrich, Nathaniel Evans

Objective Depersonalization refers to the sensation of being detached from one's body, often associated with feelings of loss of control over one's own body, actions, or thoughts. Derealization refers to the altered perception of one's surroundings that is ...

Magnetic Resonance Spectroscopy in Schizophrenia: Evidence for Glutamatergic Dysfunction and Impaired Energy Metabolism

Lijing Xin, João Miguel das Neves Duarte

In the past couple of decades, major efforts were made to increase reliability of metabolic assessments by magnetic resonance methods. Magnetic resonance spectroscopy (MRS) has been valuable for providing in vivo evidence and investigating biomarkers in ne ...

Neuroligin-2 expression in the prefrontal cortex is involved in attention deficits induced by peripubertal stress

Maria del Carmen Sandi Perez, Stamatina Tzanoulinou, Jocelin Grosse, Olivia Zanoletti, Orbicia Riccio Wicht

Emerging evidence indicates that attention deficits, which are frequently observed as core symptoms of neuropsychiatric disorders, may be elicited by early life stress. However, the mechanisms mediating these stress effects remain unknown. The prefrontal c ...

The 16p11.2 locus modulates brain structures common to autism, schizophrenia and obesity

Nouchine Hadjikhani, Loyse Hippolyte

Anatomical structures and mechanisms linking genes to neuropsychiatric disorders are not deciphered. Reciprocal copy number variants at the 16p11.2 BP4-BP5 locus offer a unique opportunity to study the intermediate phenotypes in carriers at high risk for a ...

Upregulation of the Rostral Anterior Cingulate Cortex can Alter the Perception of Emotions: fMRI-Based Neurofeedback at 3 and 7 T

Yury Koush

Recent advances in real-time functional magnetic resonance imaging (rt-fMRI) techniques enable online feedback about momentary brain activity from a localized region of interest. The anterior cingulate cortex (ACC) as a central hub for cognitive and emotio ...

Hippocampal neuroligin-2 links early-life stress with impaired social recognition and increased aggression in adult mice

Maria del Carmen Sandi Perez, Jocelin Grosse, Alexandre Claude Gustave Bacq, Céline Fournier

Early-life stress is a key risk factor for the development of neuropsychiatric disorders later in life. Neuronal cell adhesion molecules have been strongly implicated in the pathophysiology of psychiatric disorders and in modulating social behaviors associ ...
