Polysomnography
Delta waves and low levels of physiological activity are characteristic of deep non-REM sleep. These slow brain waves are associated with the deepest stages of sleep where the body is at its most restorative and rejuvenating state.
During sleep, your heartbeat tends to slow down and become more regular. This is because the body enters a state of rest and relaxation, causing a decrease in overall physiological activity. However, certain sleep disorders or medical conditions can affect the heart rate during sleep, leading to variations in heartbeat patterns.

Polysomnography is a comprehensive sleep study that involves monitoring multiple physiological functions during sleep, such as brain waves, eye movements, muscle activity, and heart rhythm. Other sleep studies may focus on specific aspects of sleep disorders, such as monitoring breathing patterns in a sleep study for sleep apnea. Polysomnography provides a more detailed and holistic assessment of sleep compared to other sleep studies.

The rhythmic bursts of brain activity that occur during Stage 2 sleep are called sleep spindles. These are short bursts of brain waves that help in the consolidation of memories and are characteristic of this stage of sleep.
Yes, brain waves can be measured using a device called an electroencephalogram (EEG). EEG measures the electrical activity in the brain by placing electrodes on the scalp, and it is used to diagnose various brain disorders and monitor brain activity during sleep or anesthesia.
dreams are a byproduct of brain activity during sleep
A sleep study, also known as a polysomnogram, is a test that measures various physical factors during sleep, such as brain activity, heart rate, breathing patterns, and body movements. It helps diagnose sleep disorders like sleep apnea, narcolepsy, and insomnia by providing detailed information on how these factors impact a person's sleep quality and patterns.
The clinical study of sleep is called polysomnography. It involves monitoring various physiological parameters such as brain waves, heart rate, and breathing patterns during sleep to diagnose sleep disorders.
