Awake fMRI Data on Canine Face Processing in Temporal Cortex

Encompassing functional magnetic resonance imaging (fMRI) data from six awake, unrestrained dogs. It was used to identify a face-selective region in the canine temporal lobe that responds more to human and dog faces than to objects. The data supports research on cross-species neural specialization for face processing.

Use Cases

• Analyze fMRI response patterns in the canine temporal lobe to movies of human faces versus everyday objects.
• Compare neural activation in the candidate dog face area between images of human faces, dog faces, and objects.
• Investigate the absence of face selectivity in dog primary visual cortex relative to the temporal lobe region.
• Study the neural basis of dogs' sensitivity to human social cues using face-selective fMRI signals.

Strengths

• Data is from six dogs scanned while awake and without restraint or sedation, a notable methodological achievement.
• Provides first evidence for a face-selective region in the temporal cortex of a non-primate species.
• Includes responses to multiple stimulus types: movies of human faces, images of human faces, dog faces, and objects.

Limitations

• Small sample size of six dogs, limiting statistical power and generalizability.
• Specific data dimensions, file formats, and size are unknown from the provided input.
• Data collection required extensive training of dogs to remain motionless, which may not be replicable in all populations.
