This study has established specific ultrasound parameters in the use of low-intensity, low-frequency ultrasound stimulation (LILFUS), designed to mimic the brainwave patterns of theta and gamma oscillations observed during learning and memory processes to induce predictable and long-lasting changes in brain function.

    The low intensity, low frequency is the new part…

    Ultrasound stimulation has been around for a while

    How was the ultrasound delivered? A fancy science probe? Can I just recreate this wave form and stick my head near a subwofer.

      Ultrasound = higher frequency than human hearing

      Infrasound = lower frequency than human hearing

      Subwoofers have a low resonant frequency. You want a tweeter that can go well above the range of human hearing to get a speaker that can produce ultrasound.

        I realized my mistake a few minutes after typing that and was hoping people would just take it as a meme I was thinking the gamma and theta frequencies but that 500khz is the actual important part that needs special tech.
