Alterations in amygdala function explain how aging and loneliness impair trust learning

This study shows that aging and loneliness impair trust learning through reduced amygdala function and altered reward signaling.

Good dog, bad wolf: Debunking evolutionary preparedness to fear wolves

This study investigates neural and behavioral responses to wolves, dogs, and snakes, finding that wolves are perceived as more threatening despite similar neural responses to dogs.

SpiDa-MRI, behavioral and (f)MRI data of adults with fear of spiders

The paper presents a database of fMRI and behavioral data from adults with spider phobia, including neural patterns and psychological dimensions.

Functional mapping of the somatosensory cortex using noninvasive fMRI and touch in awake dogs

This study maps somatosensory processing in awake dogs using fMRI, identifying activation in primary and secondary somatosensory areas and other regions, with evidence of lateralization and higher-order processing.

Amygdala habituation during exposure is associated with failure to reduce phobic symptoms

This study examines amygdala responses during exposure therapy for spider phobia, finding that increased amygdala activation correlates with better clinical outcomes, supporting the inhibitory learning model over the habituation model.

Pre- and post-task resting-state differs in clinical populations

The paper compares resting-state functional connectivity before and after tasks in clinical populations, finding task-induced changes that impact biomarker detection.

Validation of a new coil array tailored for dog functional magnetic resonance imaging (fMRI) studies

The paper validates a new coil array for dog fMRI, showing improved signal-to-noise ratio compared to human knee coils in structural and functional imaging.

Effective connectivity reveals distinctive patterns in response to others' genuine affective experience of disgust as compared to pain

The paper investigates neural responses to genuine vs. pretended disgust using effective connectivity and finds distinct brain network involvement compared to pain empathy.

Neural dynamics between anterior insular cortex and right supramarginal gyrus dissociate genuine affect sharing from automatic responses to pretended pain

In amygdala we trust: different contributions of the basolateral and central amygdala in learning whom to trust

This fMRI study identifies distinct roles of the basolateral and central amygdala in trust learning, showing BLA involvement in outcome evaluation and CeA in decision planning.

Determinants of Real-Time fMRI Neurofeedback Performance and Improvement: a Machine Learning Mega-Analysis

This study uses machine learning to analyze 608 participants and identifies two factors improving neurofeedback performance: pre-training no-feedback runs and training patients over healthy participants.

Tailored haemodynamic response function increases detection power of fMRI in awake dogs (Canis familiaris)

This paper develops a tailored haemodynamic response function for dogs, improving fMRI detection power by accounting for species-specific differences in BOLD signal timing.

Can we predict real-time fMRI neurofeedback learning success from pre-training brain activity?

This study investigates whether pre-training brain activity can predict success in real-time fMRI neurofeedback learning across 24 studies and 401 participants, finding a weak correlation but no consistent predictors.

Individual differences in successful self-regulation of the dopaminergicmidbrain

This study examines how individual differences in self-regulation of the dopaminergic midbrain relate to cognitive control and reward sensitivity during neurofeedback training.

Self-regulation of the Dopaminergic Reward Circuit in Cocaine Users with Mental Imagery and Neurofeedback

This study shows that cocaine users can self-regulate their reward system using non-drug imagery and that real-time fMRI neurofeedback enhances this ability.
