2022.10.12. Dr Karl Kruszelnicki (Dr Karl) Australian science communicator and popularize. Where/how/when did dogs arrive as our besties (so that today, we have gumboots and seat belts for them)? How come your frontal brain responds to cuddling/patting a dog?How come when you lock gaze with a female (but not a male) dog, both of you get a sudden boost in oxytocin (the “love” hormone) levels? Why is dog vision different from ours? (We humans love objects, but dogs love actions – at least, according to MRI Scans of dogs that had been taught to sit peacefully inside a noisy MRI Scanner).
