Do Dogs Dream of Opposable Thumbs?

Dogs may be hoping to play "Fetch" in a new way!


A dream by Gracie, a 7-year old beagle, was determined to a 93% confidence level to be about having opposable thumbs. Her visual cortex patterns matched that of dog paws with an opposable digit that was holding a ball.


Brain scanning has become so good that it can reliably determine what objects an animal is dreaming about. Tested in humans first, patterns in the visual cortex can be correlated with what humans are reporting they are thinking about.


Now, this technique has been extrapolated to other mammals, whose visual cortices are very similar to humans.
