Non-invasive techniques

Definition

Non-invasive techniques are methods used to assess or interact with biological systems without penetrating the skin or disrupting the body's integrity. In neuroprosthetics, these techniques are vital for monitoring brain activity and interfacing with neural structures while minimizing risk and discomfort for the patient. Their significance lies in enabling safe, effective therapies and assessments that enhance our understanding of neurological conditions.
