Dog and Human Brains Represent Human Emotional Bodies with Asymmetric Encoding of Happiness and Anger

This study shows that dogs and humans have similar neural representations of human bodily emotions, with happiness and anger encoded asymmetrically in distinct brain regions.

An annotated bioacoustic dataset of dog vocalizations and related sounds during dog-human social play

The paper presents a bioacoustic dataset of dog-human social play vocalizations with annotations and metadata, showing acoustic differences across individuals.

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.

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.

Dog brain atlas generated via spatially constrained spectral clustering

The paper generates a multi-scale functional dog brain atlas using spatially constrained spectral clustering and validates its replicability and coherence across scales.

Acute stress reduces risk-aversion by changing magnitude perception

This paper shows acute stress reduces risk-aversion by altering magnitude perception, as evidenced by behavioral and neural changes in payoff valuation.

Entorhinal grid-like codes for visual space during memory formation

The paper shows saccade-based grid-like codes in the entorhinal cortex during scene image study, linked to recognition memory performance.

Comparative neuroimaging of the carnivoran brain: Neocortical sulcal anatomy

This study examines neocortical sulcal anatomy across 26 carnivoran species using neuroimaging to identify patterns related to behavior and ecology.

Nature exposure induces hypoalgesia by acting on nociception-related neural processing

This study shows that nature exposure reduces pain perception by altering specific neural pain processing pathways, not just through general effects or reporting bias.

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.

Action observation reveals a network with divergent temporal and parietal lobe engagement in dogs compared to humans

This study compares the neural networks involved in action observation between dogs and humans using fMRI, finding similar somatosensory and temporal lobe involvement but less parietal lobe engagement in dogs.

Functionally analogous body- and animacy-responsive areas in the dog (Canis familiaris) and human occipito-temporal lobe

This study identifies functionally similar occipito-temporal regions in dogs and humans involved in perceiving animate entities and bodies, with humans showing additional face-specific regions.

Testosterone eliminates strategic prosocial behavior in healthy males

This study shows that testosterone reduces strategic prosocial behavior in males when they are being watched, without affecting reinforcement learning itself.

Entorhinal grid-like codes and time-locked network dynamics track others navigating through space

The paper shows that entorhinal grid-like codes track others' movement in social navigation and are time-locked to network dynamics involving multiple brain regions.

Effects of dopamine D2 and opioid receptor antagonism on the trade-off between model-based and model-free behavior in healthy volunteers

This study investigates how dopamine D2 and opioid receptor antagonism affects the balance between model-based and model-free behavior in healthy volunteers, finding that D2 antagonism increases model-based behavior while opioid antagonism has no significant effect.

Blocking D2/D3 dopamine receptors increases volatility of beliefs when we learn to trust others

This study shows that blocking D2/D3 dopamine receptors increases belief volatility during trust learning, particularly in individuals with higher dopamine availability.

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.

A causal role of the human left temporoparietal junction in computing social influence during goal-directed learning

This study uses brain stimulation and computational modeling to show that left TPJ causally influences how individuals adjust their choices based on others' dissenting opinions during learning.

Neuro-Computational Foundations of Moral Preferences

This study challenges the common-currency hypothesis by showing distinct neural representations for moral and financial values in specific brain regions.

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

Opioid-blunted cortisol response to stress is associated to increased negative mood and wanting of social reward

The paper examines how morphine affects cortisol response to stress and links it to changes in negative mood and social reward seeking in humans.

Effects of non-invasive brain stimulation on visual perspective taking: A meta-analytic study

This study meta-analyzes the effects of non-invasive brain stimulation on visual perspective taking, finding small effects and no strong evidence for higher-level mental rotation tasks.

A causal role for estradiol in human reinforcement learning

This study shows estradiol increases reward sensitivity in men, with effects moderated by baseline dopamine levels.

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.

Durable memories and efficient neural coding through mnemonic training using the method of loci

This study shows that mnemonic training improves durable memory formation by reducing task-based brain activation and enhancing consolidation.

Placebo analgesia does not reduce empathy for naturalistic depictions of others' pain in a somatosensory specific way

This study investigates whether placebo analgesia affects empathy for pain by examining neural responses to naturalistic depictions of others' pain in a somatotopically matched manner.

Beyond sharing unpleasant affect - evidence for pain-specific opioidergic modulation of empathy for pain

This study investigates whether placebo analgesia affects affective touch and pain empathy, finding domain-general effects for touch but pain-specific opioidergic modulation for pain empathy.

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.

Another's pain in my brain: No evidence that placebo analgesia affects the sensory-discriminative component in empathy for pain

This study investigates whether placebo analgesia affects the sensory-discriminative component of empathy for pain and finds no evidence of such effects.
