Question

What is Electrocortogram (ECoG)?

(a) A test to measure brain activity using electrodes placed directly on the brain's surface.
(b) A test to measure electrical activity in the muscles.
(c) A procedure to monitor heart rate using electrical sensors.
(d) A technique to measure lung capacity using electrical impulses.

Answer 1

An Electrocortogram (ECoG) is a medical test to measure brain activity by placing electrodes directly on the brain's surface.

Step-by-step explanation:

An Electrocortogram (ECoG) is a medical test designed to measure the electrical activity of the brain. This procedure involves placing electrodes directly onto the exposed surface of the brain. The choice (a) 'A test to measure brain activity using electrodes placed directly on the brain's surface.' is the correct answer to the question. Unlike the electrocardiogram (ECG), which measures the electrical activity of the heart, ECoG is used to assess the electrical patterns and activity within the brain's cerebral cortex. ECoG can provide valuable information regarding brain function and is often used in neurological studies and during certain types of brain surgery.
