Identification of biopsychological trait markers in functional neurological disorders

Weber et al. provide evidence in support of a stress-diathesis model of functional neurological disorders. They identify trauma history in the form of emotional neglect as a psychological risk factor, and reduced hippocampus and amygdala volume as a predis ...

Metabolic signature in nucleus accumbens for anti-depressant-like effects of acetyl-L-carnitine

Rolf Gruetter, Maria del Carmen Sandi Perez, Jocelin Grosse, João Pedro de Matos Rodrigues, Antoine Timothée Cherix, Thomas Didier Larrieu

Emerging evidence suggests that hierarchical status provide vulnerability to develop stress-induced depression. Energy metabolic changes in the nucleus accumbens (NAc) were recently related to hierarchical status and vulnerability to develop depression-lik ...

Involvement of the agmatinergic system in the depressive-like phenotype of the Crtc1 knockout mouse model of depression

Pierre Magistretti, Jean-René Cardinaux

Recent studies implicate the arginine-decarboxylation product agmatine in mood regulation. Agmatine has antidepressant properties in rodent models of depression, and agmatinase (Agmat), the agmatine-degrading enzyme, is upregulated in the brains of mood di ...

Backward masking performance in patients with functional psychoses

Michael Herzog, Maya Roinishvili

In visual backward masking, a target is followed by a blank screen (ISI - Inter-stimulus-interval) and, then, a mask which deteriorates target processing. Schizophrenic patients show strong but complex processing deficits in visual masking compared to heal ...

Hippocampal neuroligin-2 overexpression leads to reduced aggression and inhibited novelty reactivity in rats

Maria del Carmen Sandi Perez, Jocelin Grosse, Orbicia Riccio Wicht, Olivia Zanoletti, Céline Fournier

Disturbances of the excitation/inhibition (E/I) balance in the brain were recently suggested as potential factors underlying disorders like autism and schizophrenia resulting in associated behavioral alterations including changes in social and emotional be ...

Coherence and Topological Defects in Exciton-Polariton Condensates

Francesco Manni

Exciton-polaritons are hybrid quasi-particles, eigenstates of the strong coupling regime between light and matter. Their Bose-Einstein condensation has been recently demonstrated, opening the way to several fundamental investigations on the associated phen ...

Fractal temporal organization of motricity is altered in major depression

Kamiar Aminian, Anisoara Ionescu

Objective: Motor changes in major depression (MD) may represent potential markers of treatment response. Physiological rhythms (heart rate/gait cycle/hand movements) have been recently shown to be neither random nor regular but to display a fractal tempora ...

Backward masking reveals different visual processing of schizophrenic and depressive patients

Michael Herzog, Maya Roinishvili

Visual backward masking is a very sensitive tool for studying early visual processing deficits and a reliable endophenotype of schizophrenia. Mental diseases strongly overlap in many aspects, for example, in psychopathology, cognition, and genetics. Here, ...

Evidence for biological roots in the transgenerational transmission of intimate partner violence

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Vandana Veenit, Basira Salehi, Guillaume Poirier, Cristina Marquez Vega, Xavier Fontana

Intimate partner violence is a ubiquitous and devastating phenomenon for which effective interventions and a clear etiological understanding are still lacking. A major risk factor for violence perpetration is childhood exposure to violence, prompting the p ...

Mean-field phase diagram of the one-dimensional Bose gas in a disorder potential

Vincenzo Savona, Luca Fontanesi

We study the quantum phase transition of the 1D weakly interacting Bose gas in the presence of disorder. We characterize the phase transition as a function of disorder and interaction strengths, by inspecting the long-range behavior of the one-body density ...

A model for the involvement of neural cell adhesion molecules in stress-related mood disorders

Maria del Carmen Sandi Perez, Reto Bisaz

Critical interactions between genetic and environmental factors -- among which stress is one of the most potent non-genomic factors -- are involved in the development of mood disorders. Intensive work during the past decade has led to the proposal of the n ...

Realistic heterointerface model for excitonic states in growth-interrupted GaAs quantum wells

Vincenzo Savona

We present a model for the disorder of the heterointerfaces in GaAs quantum wells including long-range components like monolayer island formation induced by the surface diffusion during the epitaxial growth process. Taking into account both interfaces, a d ...
