News — In a world first, veterinary scientists at Université de Montréal have found a way to scan the brains of cats while they’re awake, using electrodes concealed under specially knitted wool caps.

When being tested for chronic pain from common conditions like osteoarthritis, awake cats tend to shake off and chew the wired electrodes placed on their heads to produce electroencephalograms (EEGs).

To prevent that, cats are normally sedated through the procedure.

Now, in a study  in the Journal of Neuroscience Methods, researchers led by  and  of UdeM’s  report a new technique to keep the electrodes in place: by placing them in crocheted beanies.

In all, 11 adult cats with osteoarthritis were tested.

After assessing their stress and pain through stimuli passed through the electrodes, the scientists then went about exposing the cats to soothing stimuli such as coloured lights and comforting smells, as a way to ease their suffering.

The study – which is already beginning to make headlines around the world in publications such as  – “opens new avenues for investigating feline chronic pain and its potential modulation through sensory interventions,” the study concludes.

Next up: a national and international blitz to make the work even better known.

Co-author , a Ph.D. student, recently presented preliminary results of the UdeM team’s work on several applications of the EEG assessments – in particular, pain sensitization – to the Royal Society of Medicine, in London, England.

“We now plan to obtain  funding, in partnership with private companies, to enable us to establish a genuine EEG signature for chronic pain, and many other applications that will enable us to automate chronic pain detection in the future,” said Troncy.

One example: a collaboration with UdeM computational psychiatry professor and CHU Sainte-Justine researcher  to test the synchronicity of cerebral waves between cats (and also dogs) and their owners.
