Summary
Optimizing electrical cortical stimulation (ECS) timing based on high gamma activity (HGA) dynamics significantly reduces errors and slows responses. Precise timing of short-ECS, aligned with HGA, is crucial for effective neuromodulation.
Area of Science:
- Neuroscience
- Electrophysiology
- Brain Stimulation
Background:
- Routine electrical cortical stimulation (ECS) can evoke symptoms and carries seizure risks.
- High Gamma Activity (HGA) distribution in electrocorticography (ECoG) shows stable patterns, unlike ECS-induced symptoms.
- Variations in ECS-induced symptoms may stem from inconsistent stimulation timing.
