Dogs’ brains — are they symmetrical?

To the effortless observer , the skull of an average dog may look more or less left over / in good order symmetrical . But are they really ?

More progress has recently been made towards resolve this enquiry . A joint inquiry squad from theUniversity of Bari , and theUniversity of Trento , in Italy , perform non - wild compute imaging ( CT ) scans of the head teacher of a XII dogs . resolution of the scans showed that seven had a larger justly hemisphere , two had a turgid unexpended hemisphere , and two render no appreciable divergence .

“ This right - biased hemispheric asymmetry support data reported previously using post - mortem morphological studies in both dogs and other mammalian species . ”

– say the research worker . Their research paper ‘ Volumetric assessment of cerebral asymmetries in dogs ‘ is schedule for publication in a succeeding variation of the diary Laterality .

Note 1 : Mathematically fain readers will have distinguish that the reported sum is one dog forgetful of the full pack – sadly , the paper ’s precis provides little or no clarification on this .

Note 2 : The study builds the portfolio of dogtooth imbalance piece of work at the University of Bari , which has previously investigated leave / right bias indogs ’ buns waggings .
