Stress, noradrenaline, and realistic prediction of mouse behaviour using reinforcement learning

Maria del Carmen Sandi Perez, Wulfram Gerstner, Gediminas Luksys

Suppose we train an animal in a conditioning experiment. Can one predict how a given animal, under given experimental conditions, would perform the task? Since various factors such as stress, motivation, genetic background, and previous errors in task perf ...

Fear conditioning enhances spontaneous AMPA receptor-mediated synaptic transmission in mouse hippocampal CA1 area

Maria del Carmen Sandi Perez, Lisa Conboy

AMPA receptor-mediated synaptic modifications in the amygdala have been reported to sustain cued fear conditioning. However, the hippocampal formation is also critically involved in fear learning. Therefore, we examined whether fear conditioning is also ac ...

Novelty of Behaviour as a Basis for the Neuro-evolution of Operant Reward Learning

Andrea Soltoggio

An agent that deviates from a usual or previous course of action can be said to display novel or varying behaviour. Novelty of behaviour can be seen as the result of real or apparent randomness in decision making, which prevents an agent from repeating exa ...

An Imitation Model based on Central Pattern Generator with application in Robotic Marionette Behavior Learning

Mostafa Ajallooeian

Most of the Central Pattern Generator (CPG) models are based on defining explicit dynamical systems and finding the appropriate parameters. In this paper, we propose a novel CPG model that is based on altering a nonlinear oscillator to obtain desired limit ...

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 ...

Calcineurin inhibition in splenocytes induced by pavlovian conditioning

Raphaël Doenlen

Pavlovian conditioning is one of the major neurobiological mechanisms of placebo effects, potentially influencing the course of specific diseases and the response to a pharmacological therapy, such as immunosuppression. In our study with behaviorally condi ...

Behavioural conditioning of immune functions: how the central nervous system controls peripheral immune responses by evoking associative learning processes

Raphaël Doenlen

During the last 30 years of psychoneuroimmunology research the intense bi-directional communication between the central nervous system (CNS) and the immune system has been demonstrated in studies on the interaction between the nervous-endocrine-immune syst ...

KAP1-mediated epigenetic repression in the forebrain modulates behavioral vulnerability to stress

Maria del Carmen Sandi Perez, Didier Trono, Maria Isabel Cordero Campana, Jean-Charles Bensadoun, Reto Bisaz, Anna Claire Groner, Johan Jakobsson

KAP1 is an essential cofactor of KRAB-zinc finger proteins, a family of vertebrate-specific epigenetic repressors of largely unknown functions encoded in the hundreds by the mouse and human genomes. Here, we report that KAP1 is expressed at high levels and ...

Identification of the matrix elastoplastic properties in reinforced active brazing alloys

John Botsis, Matteo Galli, Joël Cugnoni

The mechanical response of the reinforced active alloy Incusil (TM) ABA (R)-SiC is studied. Specimens with up to 27 vol.% SiC particles are produced and tested in tension. The presence of the reinforcement leads to modifications in the alloy mechanical res ...

Upregulation of polysialylated neural cell adhesion molecule in the dorsal hippocampus after contextual fear conditioning is involved in long-term memory formation

Maria del Carmen Sandi Perez

The role of the hippocampus in pavlovian fear conditioning is controversial. Although lesion and pharmacological inactivation studies have suggested a key role for the dorsal hippocampus in contextual fear conditioning, the involvement of the ventral part ...
