Clinicians have found a correlation between Botox and easing depression

As anyone who has a canine companion in their life can attest, dogs are uncannily good at understanding what humans are trying to tell them. Now, a study from Eötvös Loránd University, Hungary, has found a clue as to why: dogs process speech in a way that’s similar to humans. Researchers measured the changes in brain activity of awake, cooperative dogs to known praise words (clever, well done, that’s it) and unknown, neutral words (such, as if, yet) using an fMRI scanner. They found that pooches process speech in the same hierarchical way as humans with the intonation or emotion of our voices being dealt with in the ‘lower order’ subcortical regions and the meaning of known words being dealt with in the ‘higher order’ cortical regions.
