Morphology

encephalograph = encephalo + graph

This is a specialized scientific term built from classical combining forms meaning 'brain' and 'recording instrument,' which is not readily inferable for an average learner.

Etymology

The word encephalograph comes from Greek parts: encephalo- meaning 'in the head' and -graph meaning 'to write' or 'record', like the -graph in photograph. So, an encephalograph is a machine that 'writes' or records the brain's electrical activity, which is why doctors use it to monitor brain waves.
