Decoding Odor Mixtures in the Dog Brain: An Awake fMRI Study

This study uses awake fMRI in dogs to show that odor mixtures are processed configurally in the brain, with better classification using multiclass models over multilabel models.

Canine sense of quantity: evidence for numerical ratio-dependent activation in parietotemporal cortex

The paper investigates numerical perception in dogs using fMRI, finding ratio-dependent activation in parietotemporal cortex, suggesting a conserved mechanism for quantity estimation across mammals.

Awake fMRI Reveals Brain Regions for Novel Word Detection in Dogs

This study uses awake-fMRI to identify brain regions in dogs involved in novel word detection, finding greater activation for pseudowords in parietotemporal cortex and word-specific patterns in temporal and limbic regions.

Awake fMRI Reveals Covert Arousal in Aggressive Dogs Under Social Resource Threat

The paper uses fMRI to show that aggressive dogs have higher amygdala activation when observing their owner interacting with a fake dog compared to a food bucket, suggesting a neurobiological basis for dog-directed aggression.

FUNCTIONAL MRI IN AWAKE DOGS PREDICTS SUITABILITY FOR ASSISTANCE WORK

This study uses fMRI to predict service dog suitability by analyzing brain responses to reward and stranger interactions, finding high accuracy in predicting success.

Awake Canine fMRI Predicts Dogs’ Preference for Praise Versus Food

This study uses fMRI in awake dogs to show that caudate activation predicts preference for social praise over food, revealing individual differences in social reward value.
