We Induced Smells With Ultrasound (writetobrain.com)

Article summary

Researchers used focused ultrasound to stimulate the scent-processing brain regions, inducing distinct scents such as a campfire burn or fresh air in two people. The setup involved pointing an ultrasound probe at the forehead and angling it downward towards the olfactory bulb. The team found that different focal spots corresponded to different smells, which were replicated and validated through blind trials. The study's findings suggest that the olfactory system could potentially be used as a channel for non-invasive neuromodulation.

What commenters say

• The ability to induce specific smells through ultrasound stimulation could have significant implications for fields such as virtual reality and neuroscience.
• Some commenters are skeptical about the safety and efficacy of the method, suggesting that the smells may be a result of byproducts of the process rather than actual stimulation of the olfactory bulb.
• The discovery could potentially be used to develop new treatments for anosmia or other olfactory disorders, and may also have applications in the field of neuroplasticity.
• There are concerns about the potential misuse of this technology, particularly in the context of advertising or social control, and some commenters are hesitant to trust companies with direct access to their brain.
• The fact that the team was able to induce a range of smells, including unpleasant ones, suggests that the method may be tapping into the brain's natural ability to detect and respond to different odors.
• Some commenters speculate that the technology could be used to enhance or manipulate human experience, including the possibility of creating new forms of art or entertainment that incorporate smell.
• The study's findings may also have implications for our understanding of the neural basis of smell perception and the organization of the brain's olfactory system.
• There are also humorous and satirical comments about the potential applications of the technology, including its possible use in the adult entertainment industry.
