Explanation of "Delta Wave"

Definition:
A "delta wave" is a type of brainwave that is measured by a machine called an encephalogram (or EEG). These waves are the normal brain activity when a person is in deep, dreamless sleep. Delta waves have a high voltage and a low frequency, meaning they happen slowly (1 to 4 times per second).

• When to use: You can use the term "delta wave" when talking about sleep, brain activity, or discussions about neuroscience.
• Where to use: It is often used in scientific or medical contexts, especially when studying sleep patterns or brain function.

Example Sentence
