Question

2. Describe in brief what the MRI, ECG and EEG are.​

Answer 1

1.EEG(electroencephalography)

measures the electrical activity of our brain via electrodes that are placed on the scalp. It tells us, from the surface measurements, how active the brain is.

2.MRI (magnetic resonance imaging)

provides a map of the brain – how it looks at a set moment in time.

This structural information can be useful for determining how the sizes of certain brain areas compare across people, or if there is something abnormal about a particular brain (a tumor for example).

3.ECG(electrocardiography)

is a test that checks how your heart is functioning by measuring the electrical activity of the heart. With each heart beat, an electrical impulse (or wave) travels through your heart. This wave causes the muscle to squeeze and pump blood from the heart.

An ECG measures and records the electrical activity that passes through the heart. A doctor can determine if this electrical activity is normal or irregular.
