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

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

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 ...

Vibration monitoring based on optical sensing of mechanical nonlinearities in glass suspended waveguides

Yves Bellouard, Tao Yang, Pieter Vlugter, Enrico Casamenti

Vibration monitoring plays a key role in numerous applications, including machinerypredictive maintenance, shock detection, space applications, packaging-integrity monitoring andmining. Here, we investigate mechanical nonlinearities inherently present in s ...

Effective stress for unsaturated active clays and in-situ effective stress estimation methodology

Angelica Tuttolomondo

The complexity of the mechanics of active clays and, more generally, of geomaterials with clay minerals, under saturated and unsaturated conditions, still provides relevant scientific challenges today. Equally relevant challenges are the understanding of t ...

Differential Susceptibility to the Impact of the COVID-19 Pandemic on Working Memory, Empathy, and Perceived Stress: The Role of Cortisol and Resilience

Maria del Carmen Sandi Perez

There are important individual differences in adaptation and reactivity to stressful challenges. Being subjected to strict social confinement is a distressful psychological experience leading to reduced emotional well-being, but it is not known how it can ...

Music influences vividness and content of imagined journeys in a directed visual imagery task

Steffen Alexander Herff, Gabriele Cecchetti, Ken Jacques Alfonso Deguernel

Directed, intentional imagination is pivotal for self-regulation in the form of escapism and therapies for a wide variety of mental health conditions, such anxiety and stress disorders, as well as phobias. Clinical application in particular benefits from i ...

Initial effective stress controls the nature of earthquakes

Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Fabian Barras

Modern geophysics highlights that the slip behaviour response of faults is variable in space and time and can result in slow or fast ruptures. However, the origin of this variation of the rupture velocity in nature as well as the physics behind it is still ...

Programming effects of peripubertal stress on spatial learning

Maria del Carmen Sandi Perez, Stamatina Tzanoulinou, Cristina Marquez Vega

Exposure to adversity during early life can have profound influences on brain function and behavior later in life. The peripubertal period is emerging as an important time-window of susceptibility to stress, with substantial evidence documenting long-term ...

Anisotropic behaviour of shallow opalinus clay

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci, Alberto Minardi

Opalinus Clay shale, the selected host geomaterial of a high-level radioactive waste repository in Switzerland, was sourced at shallow depth in a borehole in the northern part of the country. Pairs of specimens, retrieved from the same depth were prepared ...

An energetic view of stress: Focus on mitochondria

Maria del Carmen Sandi Perez

Energy is required to sustain life and enable stress adaptation. At the cellular level, energy is largely derived from mitochondria – unique multifunctional organelles with their own genome. Four main elements connect mitochondria to stress: 1) Energy is r ...
