A new study reveals dogs and humans process body postures in similar ways in their brains.
Recent behavioral research has indicated that dogs, much like humans, are adept at perceiving facial expressions and bodily gestures, such as hand signals. However, whether this behavioral expertise is reflected in the dog's brain has remained a mystery until now.
To ensure the comfort of their furry participants, they developed specialized training protocols that gradually familiarized the dogs with the MRI environment. Crucially, the dogs were not sedated during the process and were free to leave the MRI at any time. However, unlike humans, the activation of these regions in dogs extended beyond visual brain areas. Interestingly, when dogs observed faces and bodies, differences in activation were also noted in areas responsible for processing smells.Magdalena Boch explains, "We humans often focus on the face when communicating. Our results suggest that faces are also an important source of information for dogs. However, body postures and holistic perception play a superior role.
