Question

Quizplus · Accepted Answer

The alpha rhythm is typically displayed when an individual is awake but relaxed, with their eyes closed. This brain wave pattern ranges from 8-13 Hz and is characterized by regular, symmetrical waves with an amplitude of around 50 microvolts. B, C, and D are not appropriate because beta rhythms are associated with mental activity, delta rhythms are found during deep sleep, and slow-wave sleep rhythms are associated with stage 3 and 4 sleep, neither of which are consistent with Frank's awake and relaxed state.
