Anxiety and Brain Mitochondria: A Bidirectional Crosstalk

Accumulating data highlight the contribution of brain mitochondria and bioenergetics to psychiatric disorders and stress-related pathologies. Although anxiety has not received much attention in this booming literature, a bidirectional interplay between anx ...

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

Maria del Carmen Sandi Perez, Rolf Gruetter, 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 ...

Neurobiological links between stress and anxiety

Maria del Carmen Sandi Perez

Stress and anxiety have intertwined behavioral and neural underpinnings. These commonalities are critical for understanding each state, as well as their mutual interactions. Grasping the mechanisms underlying this bidirectional relationship will have major ...

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

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

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

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

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 ...

Chronic corticosterone aggravates behavioral and neuronal symptomatology in a mouse model of alpha-synuclein pathology

Maria del Carmen Sandi Perez, Hilal Lashuel, Anass Chiki, Jean-Christophe Copin, João Pedro de Matos Rodrigues, Johannes Burtscher

Debilitating, yet underinvestigated nonmotor symptoms related to mood/emotion, such as depression, are common in Parkinson's disease. Here, we explore the role of depression and of the amygdala, a brain region robustly linked to mood/emotion, in synucleino ...

Pituitary dysmaturation affects psychopathology and neurodevelopment in 22q11.2 Deletion Syndrome

Dimitri Nestor Alice Van De Ville, Maria del Carmen Sandi Perez, Marie Schaer, Maude Schneider, Maëlle Chambaz, Daniela Maria Zöller

Background 22q11.2 Deletion Syndrome (22q11DS) confers strongly increased genetic risk for multiple psychiatric disorders. Similarly to the general population, rates of psychiatric comorbidity suggest that common disease mechanisms are shared across dimens ...

Alterations in brain microstructure in rats that develop abnormal aggression following peripubertal stress

Maria del Carmen Sandi Perez, Sophie Elizabeth Walker

Exposure to early adversity is implicated in the development of aggressive behaviour later in life in some but not all individuals. The reasons for the variability in response to such experiences are not clear but may relate to pre‐existing individual diff ...

Medium chain triglyceride diet reduces anxiety-like behaviors and enhances social competitiveness in rats

Maria del Carmen Sandi Perez, Carlos Canto Alvarez, Fiona Hollis

Medium-chain triglycerides (MCT) are emerging as unique dietary supplements that are potentially relevant for the amelioration of brain dysfunctions. MCT are converted into ketones and free medium chain fatty acids that, in the brain, are highly effective ...

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 ...

GABA A receptors in the ventral tegmental area control the outcome of a social competition in rats

Maria del Carmen Sandi Perez, Michael van der Kooij, Ioannis Zalachoras

Social dominance can be attained through social competitions. Recent work in both humans and rodents has identified trait anxiety as a crucial predictor of social competitiveness. In addition, the anxiolytic GABAA positive modulator, diazepam, injected eit ...
