Non-Invasive Hybrid Ultrasound Stimulation of Visual Cortex In Vivo

Bioengineering, 2023
The optic nerve is the second cranial nerve (CN II) that connects and transmits visual information between the retina and the brain. Severe damage to the optic nerve often leads to distorted vision, vision loss, and even blindness.
