Emergence in extinction of enhanced and persistent responding to ambiguous aversive cues is associated with high MAOA activity in the prelimbic cortex

Maria del Carmen Sandi Perez, Guillaume Poirier

There is a great deal of individual variability in the emotional outcomes of potentially traumatic events, and the underlying mechanisms are only beginning to be understood. In order to further our understanding of individual trajectories to trauma, its vu ...

Isoform switching of steroid receptor co-activator-1 attenuates glucocorticoid-induced anxiogenic amygdala CRH expression

Maladaptive glucocorticoid effects contribute to stress-related psychopathology. The glucocorticoid receptor (GR) that mediates many of these effects uses multiple signaling pathways. We have tested the hypothesis that manipulation of downstream factors (' ...

Implication of individual differences in glucocorticoid responsiveness to stress in the development of psychopathology-like behaviour and underlying neurobiology

Sophie Elizabeth Walker

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 ...

The electrophysiological effects of the serotonin 1A receptor agonist buspirone in emotional face processing

Fosco Bernasconi

Emotional face processing is critically modulated by the serotonergic system, and serotonin (5-HT) receptor agonists impair emotional face processing. However, the specific contribution of the 5-HT1A receptor remains poorly understood. Here we investigated ...

Predictable enriched environment prevents development of hyper-emotionality in the VPA rat model of autism

Henry Markram, Julie Meystre, Kamila Markram, Mônica Regina Favre, Deborah La Mendola, Melissa Cochrane

Understanding the effects of environmental stimulation in autism can improve therapeutic interventions against debilitating sensory overload, social withdrawal, fear and anxiety. Here, we evaluate the role of environmental predictability on behavior and pr ...

Long-term behavioral programming induced by peripuberty stress in rats is accompanied by GABAergic-related alterations in the amygdala

Maria del Carmen Sandi Perez, Stamatina Tzanoulinou, Vandana Veenit

Stress during childhood and adolescence is a risk factor for psychopathology. Alterations in γ-aminobutyric acid (GABA), the main inhibitory neurotransmitter in the brain, have been found following stress exposure and fear experiences and are often implica ...
