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 published in the Journal of Neuroscience Methods, researchers led by Éric Troncy and Aude Castel of UdeM's Groupe de recherche en pharmacologie animale du Québec report a new technique to keep the electrodes in place: by placing them in knitted beanies.
In all, 11 adult cats with osteoarthritis were tested.
