Psychobiological Vulnerability to Stress

Maria del Carmen Sandi Perez, Jorge Eduardo Castro Cifuentes

Several psychobiological factors are associated with vulnerability/resilience to stress-induced depression. Emerging evidence indicates behavioral traits, such as anxiety, can be related to depression-like symptoms after exposure to chronic stress. However ...

Trait anxiety and post-learning stress do not affect perceptual learning

Michael Herzog, Maria del Carmen Sandi Perez, Aaron Michael Clarke, Carl Kristoffer Aberg

While it is well established that stress can modulate declarative learning, very few studies have investigated the influence of stress on non-declarative learning. Here, we studied the influence of post-learning stress, which effectively modulates declarat ...

Evidence for a role of oxytocin receptors in the long-term establishment of dominance hierarchies

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Marjan Timmer

Exposure to stress can affect the establishment of dominance hierarchies. In our model, a social hierarchy established by two male rats during a first encounter is not maintained 1 week later. If one of the two rats is stressed, the stressed rat becomes su ...

The role of NCAM in auditory fear conditioning and its modulation by stress: a focus on the amygdala

Maria del Carmen Sandi Perez, Reto Bisaz

Chronic stress in rodents was shown to induce structural shrinkage and functional alterations in the hippocampus that were linked to spatial memory impairments. Effects of chronic stress on the amygdala have been linked to a facilitation of fear conditioni ...

Epigenetic transmission of the impact of early stress across generations

Johannes Gräff

Traumatic experiences in early life are risk factors for the development of behavioral and emotional disorders. Such disorders can persist through adulthood and have often been reported to be transmitted across generations. ...

Stress-induced cognitive and psychopathological alterations

Maria del Carmen Sandi Perez, Reto Bisaz

Intensive research over the past few years has provided evidence, that stress is a potent modulator of brain function and cognition. In particular cognitive and emotional processes have been shown to be susceptible to modulation by stress. Whereas acute st ...

Chronic stress-induced alterations in amygdala responsiveness and behavior - modulation by trait anxiety and corticotropin-releasing factor systems

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana

The basolateral nucleus of the amygdala (BLA) plays a key role in emotional arousal and anxiety, and expresses high levels of corticotropin-releasing factor receptor (CRFR)1. In rat brain slices, we have recently shown that afferent activation of the BLA i ...

Mid-life stress and cognitive deficits during early aging in rats: individual differences and hippocampal correlates

Maria del Carmen Sandi Perez

We explored here the possibility that mid-life stress in rats could have deleterious effects on cognitive abilities during early aging, as well as the potential role of inter-individual differences on the development of such effects. Male Wistar rats were ...

Spatial learning impairment induced by chronic stress is related to individual differences in novelty reactivity: search for neurobiological correlates

Maria del Carmen Sandi Perez

Although chronic stress has been reported to induce deleterious effects on hippocampal structure and function, the possible existence of individual differences in the vulnerability to develop stress-induced cognitive alterations was hypothesized. This stud ...

Strain and stress distributions in flexible pavements under moving loads

André-Gilles Dumont

Calculated strain distributions in flexible pavement were studied by comparison with measurements made on full-scale structures. The calculated results were obtained by elastic and viscoelastic modellings of these structures. As no stress measurements were ...
