Different Dog Breeds Have<br />Different Brains, Study Finds.<br />A recent collaborative study has found that canine<br />breeding may be responsible for varying brain anatomy. .<br />The study examined brain scans taken of 62 purebred<br />male and female dogs from 33 different species. .<br />Differences in the dog's brain anatomy<br />were found to be dependent on their long-<br />lasting partnership with humans. .<br />What we found was that the differences in brain<br />anatomy go over and above differences in body<br />size, brain size, and just general head shape.<br />And we think these differences are accounted<br />for by the selective breeding of behaviors, Erin Hecht, Harvard University, via Gizmodo.<br />One example shows that hunting dogs, such as golden<br />retrievers, have key differences in the regions of their<br />brain linked to coordination and spatial navigation. .<br />According to Hecht, this discovery could<br />lead to the use of neuroscience to refine the<br />specialized tasks that dogs are bred to perform. .<br />This might sound a little goofy, but it’s<br />also profound—our brains have been<br />shaping the brains of another species. , Erin Hecht, Harvard University, via Gizmodo
