Peripubertal stress increases play fighting at adolescence and modulates nucleus accumbens CB1 receptor expression and mitochondrial function in the amygdala

Maria del Carmen Sandi Perez, Olivia Zanoletti, Jocelin Grosse

Play fighting is a highly rewarding behavior that helps individuals to develop social skills. Early-life stress has been shown to alter play fighting in rats and hamsters as well as to increase aggressive behaviors at adulthood. However, it is not known wh ...

Model-based reinforcement learning and navigation in animals and machines

Dane Sterling Corneil

For decades, neuroscientists and psychologists have observed that animal performance on spatial navigation tasks suggests an internal learned map of the environment. More recently, map-based (or model-based) reinforcement learning has become a highly activ ...

Belief as a Wise Wager : the Neural Representation of Uncertainty, Surprise and Confidence Across Cognitive and Perceptual Domains

Leyla Loued-Khenissi

From the moment we wake up in the morning to the day's ebb when we settle in to sleep, we are bound to the task of decision-making. Some of these decisions barely register in our consciousness, if at all, while others, less shy, take a more prominent place ...

Hierarchical status predicts behavioral vulnerability and nucleus accumbens metabolic profile following chronic social defeat stress

Maria del Carmen Sandi Perez, Rolf Gruetter, Hongxia Lei, Antoine Timothée Cherix, Thomas Didier Larrieu, João Pedro de Matos Rodrigues, Maria Aranzazu Duque Moreno

Extensive data highlight the existence of major differences in individuals’ susceptibility to stress [1; 2; 3 ; 4]. While genetic factors [5 ; 6] and exposure to early life stress [7 ; 8] are key components for such neurobehavioral diversity, intriguing ob ...

Elicitation and Aggregation of Crowd Information

Goran Radanovic

This thesis addresses challenges in elicitation and aggregation of crowd information for settings where an information collector, called center, has a limited knowledge about information providers, called agents. Each agent is assumed to have noisy private ...

Social reward improves the voluntary control over localized brain activity in fMRI-based neurofeedback training

Yury Koush

Neurofeedback (NF) based on real-time functional magnetic resonance imaging (rt-fMRI) allows voluntary regulation of the activity in a selected brain region. For the training of this regulation, a well-designed feedback system is required. Social reward ma ...

Methyl Supplementation Attenuates Cocaine-Seeking Behaviors and Cocaine-Induced c-Fos Activation in a DNA Methylation-Dependent Manner

Fiona Hollis

Epigenetic mechanisms, such as histone modifications, regulate responsiveness to drugs of abuse, such as cocaine, but relatively little is known about the regulation of addictive-like behaviors by DNA methylation. To investigate the influence of DNA methyl ...

Medial Forebrain Bundle Deep Brain Stimulation has Symptom-specific Anti-depressant Effects in Rats and as Opposed to Ventromedial Prefrontal Cortex Stimulation Interacts With the Reward System

Martin Vogel

Background: In recent years, deep brain stimulation (DBS) has emerged as a promising treatment option for patients suffering from treatment-resistant depression (TRD). Several stimulation targets have successfully been tested in clinical settings, includin ...

The impact of anxiety and reward-seeking traits on social competition and the role of the mesolimbic dopaminergic system

Laura Lozano Montes

Social hierarchies are established across a range of different taxa in the animal kingdom. Given that hierarchy inequalities are highly present in nowadays society and the health problems that low rank individuals suffer from this, it is surprising that no ...

Cell-Type-Specific Sensorimotor Processing in Striatal Projection Neurons during Goal-Directed Behavior

Carl Petersen, Sylvain Crochet, Tanya C Sippy, Damien Lapray

Goal-directed sensorimotor transformation drives important aspects of mammalian behavior. The striatum is thought to play a key role in reward-based learning and action selection, receiving glutamatergic sensorimotor signals and dopaminergic reward signals ...
