Non-invasive apparatus and method for Cranial Brain Stimulation

Ultrasound (US) has received widespread attention as an emerging technology for targeted, non-invasive neuromodulation based on its ability to evoke electro-physiological and motor response As the focusing is achieved through constructive interference of the incident waves, a focal spot can be formed at depth within the tissue without affecting cells along the propagation path closer to the transducer.

Hearing is a well-known sensory phenomenon that enables humans to hear sounds at a far higher frequency than would naturally be detectable through the actual inner ear, typically by stimulation of the cochlea base by bone conduction.

Depending on the person, Normal human hearing is recognized as having an upper bound of 15–28 kHz. Second option proposes that ultrasonic signals resonate the brain and are modulated down to frequencies that the cochlea can then detect
