Using ultrasound to restore vision
Researchers are exploring the use of ultrasound waves to stimulate neurons and potentially restore vision. By using sonogenetics, scientists can genetically modify neurons to respond to ultrasound, offering a non-invasive alternative to traditional methods.
Why it matters
This emerging field could revolutionize neuro-stimulation therapies, providing safer and more precise ways to treat sensory impairments compared to invasive surgeries.
A normal human hears sound in the frequency range 20 hertz (Hz) to 20 kilohertz, and the normal loudness, measured in decibels (dB), is between 30 and 70 db. Higher volumes, e.g. 85 dB and above, can lead to hearing damage. Ultrasound is defined as sound frequencies far beyond the audible range, and are expressed in kilohertz (kHz) or megahertz (MHz).
