Pico-Driven Ultrasound Enables Scaled Acoustic Model of Home Stereo
💁🏻♀️ TIL: #MIT engineers built a stamp-sized sticker that paces the #heart using #ultrasound instead of #surgery. 🫀
The chest patch sends #sound waves to genetically sensitized heart #cells, triggering contractions. Tests on human cells and #rats show it corrects arrhythmias safely. Future versions will combine imaging and pacing in one #wearable. 🔊

@screwlisp @AmenZwa @dougmerritt You can test the high frequency response of your microphone by smashing a fork and a tablespoon together. Or two forks. Or two tablespoons. I don't remember. The more annoying, eardrum-piercing the sound is, the better. It basically has a flat spectrum into ultrasonic.
Then view the Sox spectrogram of the recording and you see if it's rolling off somewhere or going all the way to the end.

Not a treatment, but helps to control the symptoms.
"In opting for this treatment, called high-intensity focused ultrasound, Goings has joined a small but growing number of people choosing to control their Parkinson’s symptoms with permanent lesions in their brain."

A study finds that high and low frequency ultrasound can affect the aggregation of red blood cells. High and low frequencies promote aggregation and dispersion, respectively. Blood viscocity is changed as a result. Dispersal of erythrocytes promotes oxygen exchange. This may have therapeutic value for cardiovascular disease, diabetes, cancer, and Alzheimer's disease.

For decades, ultrasound has been associated with diagnostics—a routine scan in a hospital room, a monitor displaying organs, tissues, or the first image of a baby. However, researchers are now looking at ultrasound from an entirely different perspective.

🧠Another Interesting study using functional #ultrasound #imaging ( #fUSI) in behaving #ferrets: Boucher, Shamma & Boubenec show that #PremotorCortex activity during #auditory decisions reflects the animal’s internal perceptual category more than the overt motor response itself.
