Electrocorticography

Electrocorticography (ECoG) is a technique used to record electrical activity directly from the surface of the brain. By placing electrodes on the brain's surface during surgery, it captures real-time signals associated with brain functions like movement, sensation, or speech. ECoG provides high-resolution data, helping doctors understand brain patterns, especially in epilepsy treatment or planning surgeries. Unlike external methods, ECoG offers more precise readings because it is closer to the neural sources. It is valuable for both clinical diagnosis and neuroscience research, providing insights into how different parts of the brain communicate.
