Analysis of human sleep

Electroencephalography (EEG) is a technique used to obtain a measure of the brain's overall electrical activity. It involves placing an array of electrodes on a person's scalp to record brainwaves. The resulting data provides high-precision information, accurate to the millisecond, about the frequency and amplitude of these waves, making it ideal for applications like sleep studies where precise spatial information is not required.

Electroencephalography (EEG)

The electrical recording of eye movements which help identify stages of sleep.

Electro-oculography (EOG)

- The electrical recording of muscle activity (timing/ strength of contractions) which helps track change in muscle tension during the stages of sleep

Electromyography (EMG)

A sleep researcher is studying a particular stage of sleep characterized by active brain wave patterns, rapid eye movements, and a temporary, near-complete paralysis of the body's voluntary muscles. To precisely identify the moment this muscle paralysis begins, which measurement would provide the most direct evidence?
