Emotion and prediction errors: which ingredients matter? Open
Does including emotions improve reinforcement-learning models? A recent EEG study by Heffner and colleagues presents separate neural signatures for reward and emotion prediction errors. This advance invites questions about, and even holds …

Differential influence of habit components on compulsive and problematic reward-seeking behavior Open
Habitual behavior has been identified as a key process involved in a variety of mental health problems. Previous research has shown that habit is not a unitary construct. The present study examined how different components of habitual beha…

A randomized controlled trial investigating the effect of liraglutide on self-reported liking and neural responses to food stimuli in participants with obesity Open
Background/Objectives Obesity is a complex condition and the mechanisms involved in weight gain and loss are not fully understood. Liraglutide, a GLP-1 receptor agonist, has been demonstrated to successfully promote weight loss in patients…

Frontal mechanisms underlying primate calls recognition by humans Open
The ability to process verbal language seems unique to humans and relies not only on semantics but on other forms of communication such as affective vocalisations, that we share with other primate species—particularly great apes ( Hominida…

Neural substrates of parallel devaluation-sensitive and devaluation-insensitive Pavlovian learning in humans Open
Pavlovian learning depends on multiple and parallel associations leading to distinct classes of conditioned responses that vary in their flexibility following changes in the value of an associated outcome. Here, we aimed to differentiate b…

Multicomponential affective processes modulating food-seeking behaviors Open
Food rewards elicit a variety of affective responses. They emerge from multiple components, including motivational and hedonic processes. Here, we review evidence for these multiple components through an affective science lens. We describe…

Does GLP-1 receptor agonist liraglutide alter food-related sensory pleasure in patients with obesity? A randomized controlled trial Open
Background/Objectives: Obesity is a complex condition and the mechanisms involved in weight gain and loss are poorly understood. Liraglutide, a GLP-1 receptor agonist, has been demonstrated to successfully promote weight loss in patients w…

Determining the effects of training duration on the behavioral expression of habitual control in humans: a multilaboratory investigation Open
It has been suggested that there are two distinct and parallel mechanisms for controlling instrumental behavior in mammals: goal-directed actions and habits. To gain an understanding of how these two systems interact to control behavior, i…

3D-Printed Pacifier-Shaped Mouthpiece for fMRI-Compatible Gustometers Open
Gustometers have made it possible to deliver liquids in functional magnetic resonance imaging (fMRI) settings for decades, and mouthpieces are a critical part of these taste delivery systems. Here, we propose an innovative 3D-printed fMRI …

How representative are neuroimaging samples? Large-scale evidence for trait anxiety differences between fMRI and behaviour-only research participants Open
Over the past three decades, functional magnetic resonance imaging (fMRI) has become crucial to study how cognitive processes are implemented in the human brain. However, the question of whether participants recruited into fMRI studies dif…
View article: Differential contributions of ventral striatum subregions to the motivational and hedonic components of the affective processing of the reward
Differential contributions of ventral striatum subregions to the motivational and hedonic components of the affective processing of the reward Open
The ventral striatum is implicated in the affective processing of the reward, which can be divided into a motivational and a hedonic component. Here, we examined whether these two components rely on distinct neural substrates within the ve…

3D printed pacifier-shaped mouthpiece for fMRI-compatible gustometers Open
Gustometers have allowed the delivery of liquids in fMRI settings for decades and mouthpieces are a critical part of those taste delivery systems. Here we propose an innovative 3D printed mouthpiece inspired by children’s pacifiers that al…

Individual differences in learning positive affective value Open
As a fundamental process underlying how individuals learn affective value, Pavlovian learning has been used to account for the emergence of individual differences in behavior and cognition. In affective sciences, early investigations into …

Individual concerns modulate reward-related learning and behaviors involving sexual outcomes Open
Pavlovian and instrumental conditioning are fundamental processes helping organisms learn about stimuli that predict rewards in the environment and actions that lead to their obtainment. These two forms of learning and their interplay nota…

Vulnerability to relapse under stress: insights from affective neuroscience Open
In this review article, we aim at analysing the role of stress in addiction and relapse. In order to do so, we first offer a summary of the findings from affective neuroscience trying to understand compulsive reward-seeking behaviours. The…

Emotional attention for erotic stimuli: Cognitive and brain mechanisms Open
It has long been posited that among emotional stimuli, only negative threatening information modulates early shifts of attention. However, in the last few decades there has been an increase in research showing that attention is also involu…

The role of affective relevance in the processing of positive rewarding stimuli Open
In this thesis we focused on rewarding stimuli and tried to model reward processes in humans that could be related to irrational reward-seeking behaviors. We provided evidence showing that stimuli associated with reward (a) bias attention …
