Astrocytic beta(2)-adrenergic receptors mediate hippocampal long-term memory consolidation

Pierre Magistretti, Sylvain Eric Lengacher

Emotionally relevant experiences form strong and long-lasting memories by critically engaging the stress hormone/neurotransmitter noradrenaline, which mediates and modulates the consolidation of these memories. Noradrenaline acts through adrenergic recepto ...

Stress pulls us apart: Anxiety leads to differences in competitive confidence under stress

Maria del Carmen Sandi Perez, Fiona Hollis, Samuel Bendahan, John Christian Thoresen

Social competition is a fundamental mechanism of evolution and plays a central role in structuring individual interactions and communities. Little is known about the factors that affect individuals’ competitive success, particularly in humans. Key factors ...

An evolutionarily conserved role for the aryl hydrocarbon receptor in the regulation of movement

Johan Auwerx, Bart Deplancke, Laurent Mouchiroud, Evan Graehl Williams, Pénélope Andreux, Michael Vincent Frochaux

The BXD genetic reference population is a recombinant inbred panel descended from crosses between the C57BL/6 (B6) and DBA/2 (D2) strains of mice, which segregate for about 5 million sequence variants. Recently, some of these variants have been established ...

Physiological adaptation of Desulfitobacterium hafniense strain TCE1 to tetrachloroethene respiration

Christof Holliger, Julien Maillard

Desulfitobacterium spp. are ubiquitous organisms with a broad metabolic versatility and some isolates have the ability to use tetrachloroethene (PCE) as terminal electron acceptor. In order to identify proteins involved in this organohalide respiration pro ...

Stress, genotype and norepinephrine in the prediction of mouse behavior using reinforcement learning

Maria del Carmen Sandi Perez, Wulfram Gerstner, Gediminas Luksys

Individual behavioral performance during learning is known to be affected by modulatory factors, such as stress and motivation, and by genetic predispositions that influence sensitivity to these factors. Despite numerous studies, no integrative framework i ...

Stress, individual differences, and norepinephrine in reinforcement learning-based prediction of mouse behavior in conditioning and spatial learning

Maria del Carmen Sandi Perez, Gediminas Luksys

Acute stress regulates different aspects of behavioral learning through the action of stress hormones and neuromodulators. Stress effects depend on stressor's type, intensity, timing, and the learning paradigm. In addition, genetic background of animals mi ...

Stress before puberty exerts a sex- and age-related impact on auditory and contextual fear conditioning in the rat

Maria del Carmen Sandi Perez

Adolescence is a period of major physical, hormonal, and psychological changes. It is also characterized by a significant increase in the incidence of psychopathologies and this increase is gender-specific. Stress during adolescence is associated with the ...
