Cannabis use, cannabis use disorder and mental health disorders among pregnant and postpartum women in the US: A nationally representative study

Aaron Leor Sarvet

Background: Cannabis use and cannabis use disorder (CUD) are associated with mental health disorders, however the extent of this matter among pregnant and recently postpartum (e.g., new moms) women in the US is un-known. Associations between cannabis use, ...

Identifying Disease-Specific Neural Reactivity to Psychosocial Stress in Borderline Personality Disorder

Dimitri Nestor Alice Van De Ville

BACKGROUND: Patients with borderline personality disorder (BPD) typically present emotion dysregulation (ED) when faced with adversity. However, it is argued that altered stress response may be more influenced by ED than BPD-specific traits. Here, we inves ...

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 ...

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 ...

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 ...

Exploiting Long-Range Disorder in Slow-Light Photonic Crystal Waveguides: Anderson Localization and Ultrahigh Q/V Cavities

Juan Pablo Vasco Cano

The interplay between order and disorder in photonic lattices opens up a wide range of novel optical scattering mechanisms, cavity-mode resonances, and applications that can be obscured by typical ordered design approaches to photonics. Striking examples i ...

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 ...

Diazepam actions in the VTA enhance social dominance and mitochondrial function in the nucleus accumbens by activation of accumbal dopamine D1 receptors

Maria del Carmen Sandi Perez, Carlos Canto Alvarez, Jocelin Grosse, Olivia Zanoletti, Fiona Hollis, Ioannis Zalachoras, Laura Lozano Montes, Marie-Isabelle Guillot de Suduiraut

Benzodiazepines can ameliorate social disturbances and increase social competition, particularly in high-anxious individuals. However, the neural circuits and mechanisms underlying benzodiazepines’ effects in social competition are not understood. Convergi ...

Hierarchical status predicts behavioral vulnerability and nucleus accumbens metabolic profile following chronic social defeat stress

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

Extensive data highlight the existence of major differences in individuals’ susceptibility to stress [1; 2; 3 ; 4]. While genetic factors [5 ; 6] and exposure to early life stress [7 ; 8] are key components for such neurobehavioral diversity, intriguing ob ...

Effects of paternal and peripubertal stress on aggression, anxiety, and metabolic alterations in the lateral septum

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Nathalie Just, Guillaume Poirier

Early-life stress and biological predispositions are linked to mood and personality disorders related to aggressive behavior. We previously showed that exposure to peripubertal stress leads to increased anxiety-like behaviors and aggression against males a ...

Not all anxious individuals get lost: trait anxiety and mental rotation ability interact to explain performance in map-based route learning in men

Maria del Carmen Sandi Perez, John Christian Thoresen, Rebecca Francelet

Navigation through an environment is a fundamental human activity. Although group differences in navigational ability are documented (e.g., gender), little is known about traits that predict these abilities. Apart from a well-established link between menta ...

The Number of Genomic Copies at the 16p11.2 Locus Modulates Language, Verbal Memory, and Inhibition

Nouchine Hadjikhani, Borja Rodriguez Herreros, Loyse Hippolyte

BACKGROUND: Deletions and duplications of the 16p11.2 BP4-BP5 locus are prevalent copy number variations (CNVs), highly associated with autism spectrum disorder and schizophrenia. Beyond language and global cognition, neuropsychological assessments of thes ...

Mitochondrial function in the brain links anxiety with social subordination

Maria del Carmen Sandi Perez, Carlos Canto Alvarez, Olivia Zanoletti, Fiona Hollis, Laura Lozano Montes

Dominance hierarchies are integral aspects of social groups, yet whether personality traits may predispose individuals to a particular rank remains unclear. Here we show that trait anxiety directly influences social dominance in male outbred rats and ident ...

Inferring about individual drug and schizotypy effects on cognitive functioning in polydrug using mephedrone users before and after clubbing

Christine Mohr, Daniela Herzig

Objective Mephedrone has been recently made illegal in Europe, but little empirical evidence is available on its impact on human cognitive functions. We investigated acute and chronic effects of mephedrone consumption on drug-sensitive cognitive measures, ...

Female vulnerability to the development of depression-like behavior in a rat model of intimate partner violence is related to anxious temperament, coping responses, and amygdala vasopressin receptor 1a expression

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Guillaume Poirier

Exposure to violence is traumatic and an important source of mental health disturbance, yet the factors associated with victimization remain incompletely understood. The aim of the present study was to investigate factors related to vulnerability to depres ...

Learning, Stress and the Role of Personality Profiles in Rats

Maria del Carmen Sandi Perez, Basira Salehi

Stress has been shown to modulate many aspects of physiology and behavior. In particular, substantial work has confirmed that stress is a strong modulator of learning and memory processes. It is more than a century that Yerkes and Dodson have shown that re ...

From high anxiety trait to depression: a neurocognitive hypothesis

Maria del Carmen Sandi Perez

Although exposure to substantial stress has a major impact on the development of depression, there is considerable variability in the susceptibility of individuals to the adverse effects of stress. The personality trait of high anxiety has been identified ...
