Have you ever seen an encephalograph in action?

No, I haven't! What does it do?

Root Explanation

Encephalograph → It is formed from "en-" (meaning in or within), "kephalē" (Greek for head), and "graph" (meaning to write or record). The word describes a device that records activity within the head, specifically the brain.

Memory Tip

Think of recording something 'within' ('en-') the 'head' ('kephalē') — that's why an encephalograph is a device that records brain activity.
