Debunked: No, COVID-19 variants are not named after brain waves
Online posts have asserted that the Greek letter names for COVID-19 variants are references to brain waves. Greek letters are used for naming throughout science and are not specific to brain waves. With regard to COVID-19 variants, this naming convention was established by the WHO as an alternative to place names, and thus avoid stigmatising the countries where the variants have been identified. The AP has debunked this assertion.
