- This is the first comparative neuroimaging study of a nonprimate species and humans
- Functional analogies were found between dog and human nonprimary auditory cortex
- Voice areas preferring conspecific vocalizations were evidenced in the dog brain
- Brain sensitivity to vocal cues of emotional valence was found in both species
Active canine cognition scientists in Hungary continue to explore the relationship of humans and dogs leading to perhaps not so surprising findings that each has evolved with similar brain functions to process social information. Some even suggest that there has been a cultural co-evolution between the two species. (Adam Miklosi, video on SPARCS site.) “Dog and human vocalizations are thus familiar and relevant to both species.” (From Summary.)The scientist conducting the current study, Atilla Andics, et al, believes that this information may support the premise that the two species evolved as it did because of close interactions between each other. Dogs understand us well because our brains function similarly. For example, dogs, like humans, have a sensitivity to processing vocalizations, both the auditory and emotional message.
