    Hello there!

    Regarding delta waves produced by our brain during sleep,
    some sources state that these waves are from EXACTLY 0Hz to 4Hz,
    whereas others state they are from NEAR 0Hz (ie, 0.5Hz) to 4Hz.

    Could you tell which ones are right?

    Neither. For example:
    "Recent intracellu-lar analyses revealed two different oscilla-tions with distinct origins and cellular mechanisms: One of them is termed delta oscillation (1 to 4 Hz) and the other is termed slow oscillation 1 Hz). "
