New technology changes the way scientists scan cats' brains.

Canadian scientists have designed a knitted cap for cats equipped with electrodes to scan the brain activity of awake cats. This technology avoids the need for sedation in traditional methods. The research focuses on cats with chronic osteoarthritis, using the electrodes to assess pain and test the effects of soothing stimulation. This study opens new avenues for research on chronic pain in feline species and may lead to future applications for the automatic detection of chronic pain.

Electroencephalogram (EEG): A medical test that records brain electrical activity using electrodes.
