Functional MRI Neurofeedback Outperforms Cognitive Behavioral Therapy for Reducing Tinnitus Distress: A Prospective Randomized Clinical Trial

Dimitri Nestor Alice Van De Ville, Nicolas Gninenko

Background: Cognitive behavioral therapy (CBT) is the current standard treatment for chronic severe tinnitus; however, preliminary evidence suggests that real-time functional MRI (fMRI) neurofeedback therapy may be more effective. Purpose: To compare the e ...

Social isolation shortens lifespan through oxidative stress in ants

Laurent Keller, Alessandro Crespi

Social isolation negatively affects health, induces detrimental behaviors, and shortens lifespan in social species. Little is known about the mechanisms underpinning these effects because model species are typically short-lived and non-social. Using coloni ...

Transcriptomic analysis reveals mitochondrial pathways associated with distinct adolescent behavioral phenotypes and stress response

Maria del Carmen Sandi Perez, Dogukan Hazar Ülgen

Adolescent individuals exhibit great variability in cortical dynamics and behavioral outcomes. The developing adolescent brain is highly sensitive to social experiences and environmental insults, influencing how personality traits emerge. A distinct patter ...

Opposite effects of stress on effortful motivation in high and low anxiety are mediated by CRHR1 in the VTA

Maria del Carmen Sandi Perez, Olivia Zanoletti, Simone Astori, Jocelin Grosse, Marie-Isabelle Guillot de Suduiraut, Ioannis Zalachoras

Individuals frequently differ in their behavioral and cognitive responses to stress. However, whether motivation is differently affected by acute stress in different individuals remains to be established. By exploiting natural variation in trait anxiety in ...

Negative Associations of Stress and Anxiety Levels With Cytotoxic and Regulatory Natural Killer Cell Frequency in Chronic Tinnitus

Patrick Karl Alois Neff

BackgroundDepression and anxiety are known to be associated with stress-induced changes in the immune system. Bothersome tinnitus can be related to stress and often co-occurs with depression and anxiety. This study investigates associations of psychologica ...

During capsaicin-induced central sensitization, brush allodynia is associated with baseline warmth sensitivity, whereas mechanical hyperalgesia is associated with painful mechanical sensibility, anxiety and somatization

Anne-Christine Schmid

Background Mechanical hyperalgesia and allodynia incidence varies considerably amongst neuropathic pain patients. This study explored whether sensory or psychological factors associate with mechanical hyperalgesia and brush allodynia in a human experimenta ...

Using connectivity-based real-time fMRI neurofeedback to modulate attentional and resting state networks in people with high trait anxiety

Elenor Morgenroth, Francesca Saviola

High levels of trait anxiety are associated with impaired attentional control, changes in brain activity during attentional control tasks and altered network resting state functional connectivity (RSFC). Specifically, dorsolateral prefrontal cortex to ante ...

Exploring the Causes of Social Exclusion Related to Mobility for Non-Motorized Households

Vincent Kaufmann, Dominic Villeneuve

Using a lexicometric and qualitative data analysis of 57 semi-directed interviews with members of non-motorized households in the urban areas of Quebec City (Canada) and Strasbourg (France), this paper attempts to show whether living in a carless household ...

The role of the subgenual anterior cingulate cortex in dorsomedial prefrontal-amygdala neural circuitry during positive-social emotion regulation

Dimitri Nestor Alice Van De Ville, Frank Scharnowski, Yury Koush, Gwladys Rey

Positive-social emotions mediate one's cognitive performance, mood, well-being, and social bonds, and represent a critical variable within therapeutic settings. It has been shown that the upregulation of positive emotions in social situations is associated ...

Locomotion in virtual environments predicts cardiovascular responsiveness to subsequent stressful challenges

Maria del Carmen Sandi Perez, João Pedro de Matos Rodrigues, Nathalie Heidi Meyer, Stephan Streuber, Erik Hans Jakob Studer

Individuals differ in their physiological responsiveness to stressful challenges, and stress potentiates the development of many diseases. Heart rate variability (HRV), a measure of cardiac vagal break, is emerging as a strong index of physiological stress ...

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

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

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 ...

Trait anxiety on effort allocation to monetary incentives: a behavioral and high-density EEG study

Maria del Carmen Sandi Perez, João Pedro de Matos Rodrigues, Alina Veronika Irene Strasser

Trait anxiety is an important phenotype in the prediction of stress-induced neuropsychiatric disorders. While the role of trait anxiety in mental effort and cognitive impairment is well documented, much less is known about its influence on motivated behavi ...

Reactivation of Recall-Induced Neurons in the Infralimbic Cortex and the Basolateral Amygdala After Remote Fear Memory Attenuation

Johannes Gräff, Ossama Mohamed Salah El-Dien El-Sayed Ibrahim Khalaf

Whether the attenuation of traumatic memories is mediated through the suppression of the original memory trace of fear by a new memory trace of safety, or through an updating of the original fear trace towards safety has been a long-standing question at th ...

High anxiety trait: A vulnerable phenotype for stress-induced depression

Maria del Carmen Sandi Perez, Meltem Weger

A great deal of research aims to identify risk factors related to individual vulnerability to develop stress-induced psychopathologies. Here, we summarize evidence that point at anxiety trait as a significant contributor to inter-individual differences in ...
