METHOD NOTES / EEG

Record changes. Return to the question.

How can we add another observation across a process?

What it records

EEG records voltage changes detected by sensors over time. Interpretation depends on the task and analysis conditions. A waveform alone does not establish a sleep benefit.

Its role in this study

In this research story, EEG is one source of observations across time. Define the phase first, then consider signal processing, measures and other evidence.

Before interpreting

Illustrative waveforms are not study data. Each measure needs justification. This story does not equate a frequency ratio with clinical sleep staging or assess health.
