We Induced Smells With Ultrasound
First-ever ultrasound olfactory stimulation in humans. We induced distinct artificial smells like campfire and fresh air using focused ultrasound - a nose BCI breakthrough.
We pointed an ultrasound probe at the scent-processing region of the brain to obtain different sensations. Different focal spots corresponded to different smells, which we’ve replicated first-try on two people and validated with a blind trial. The sensations we obtained are: The sensation of fresh air, with a lot of oxygen The smell of garbage, like few-day-old fruit peels An ozone-like sensation, like you're next to an air ionizer A campfire smell of burning wood Here is a video from our blind tasting: Your browser does not support the video tag. The Setup Smells are processed in the olfactor
