Patterned low-intensity, low-frequency ultrasound (LILFUS) offers a safe and effective method for controlling brain functions. The ability of the human brain to adjust to both internal and external shifts, referred to as neural plasticity, is crucial for grasping cognitive processes such as memory

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.

    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.
