Anodal Block
Inhibition of neural activity at the positive electrode contact, used strategically in neurostimulation to reduce unwanted side effects.
Full Definition
Anodal block refers to the phenomenon where positive electrical charge at an electrode contact can inhibit or block neural conduction rather than stimulate it. In neuromodulation therapy, this principle is deliberately employed to create areas of neural silence adjacent to stimulation zones, helping to refine the therapeutic field and minimize unwanted sensations or motor effects. Understanding anodal block is crucial for optimizing electrode configurations and stimulation patterns.
Usage
Usage note: Technical concept requiring explanation when discussing electrode polarity configurations.
