Cambridge study aims to find out if dogs and their owners are on same wavelength

Scientists to examine if humans' and dogs' brains synchronise when they interact in a way similar to parents and babies

Standing patiently on a small fluffy rug, Calisto the flat-coated retriever is being fitted with some hi-tech headwear. But this is not a new craze in canine fashion: she is about to have her brainwaves recorded.

Calisto is one of about 40 pet dogs - from newfoundlands to Tibetan terriers - taking part in a study to explore whether their brainwaves synchronise with those of their owners when the pair interact, a phenomenon previously seen when two humans engage with each other.
