A neuro-technology company in Belfast has developed a headset which it claims will revolutionise weight loss.
The Modius was developed by Neurovalens, led by Co Antrim neuroscientist Dr Jason McKeown and Dr Paul McGeoch.
They say the apparatus, which is worn for 45 minutes every day, will send a signal to the part of the brain - the vestibular nerve - that controls fat storage. That process can cause a shift in metabolism to burn more fat and lead to weight loss.
And within one hour of use, it can lead to "significant change" in appetite.
The device can only be bought online from website Indiegogo. Its recommended retail price is $499 (£383) but the first batch has gone on sale for $249 (£191).
It's been endorsed by GP and TV medic Dr Pixie McKenna.
Dr McKeown said: "Weight gain and weight loss are controlled by your brain, which controls your appetite, your hormones, your metabolic rate, how much fat you store, and more.
"Modius resolves this issue by stimulating the vestibular nerve and activating the epicentre of it all - your hypothalamus."
Neurovalens has headquarters in Belfast's Ormeau Baths Innovation Centre and the University of California San Diego Center for Brain and Cognition.
Neurovalens has raised £1.4m in venture capital and has also received £259,000 from economic development agency Invest NI.
