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 ...

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 ...

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 ...

In vivo neurochemistry of the ventral striatum and social competition in Homo sapiens

Alina Veronika Irene Strasser

Ventral striatal function and trait anxiety have been shown to influence reward-seeking behaviour and social competition in humans. Moreover, social status perceptions have been shown to modulate ventral striatal function. The neurochemical underpinnings o ...

Disentangling resting-state BOLD variability and PCC functional connectivity in 22q11.2 deletion syndrome

Dimitri Nestor Alice Van De Ville, Marie Schaer, Daniela Maria Zöller, Maria Carmela Padula

Although often ignored in fMRI studies, moment-to-moment variability of blood oxygenation level dependent (BOLD) signals reveals important information about brain function. Indeed, higher brain signal variability has been associated with better cognitive p ...

Active pain coping is associated with the response in real-time fMRI neurofeedback during pain

Dimitri Nestor Alice Van De Ville, Kirsten Emmert

Real-time functional magnetic resonance imaging (rt-fMRI) neurofeedback is used as a tool to gain voluntary control of activity in various brain regions. Little emphasis has been put on the influence of cognitive and personality traits on neurofeedback eff ...

The period around puberty is a critical window in development. It is a time of neuroendocrine and neuroanatomical lability, rendering individuals highly sensitive to stress. Indeed, early adversity increases risk for psychopathology. The mechanisms via whi ...

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 ...

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

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti, Stamatina Tzanoulinou, 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 ...
