<prompt> Which is the EEG wave recorded in a subject who is awake but eyes closed?Alpha wavesBeta wavesTheta wavesDelta waves  <response>: Alpha waves are recorded best in the parieto-occipital region in adults at rest, i.e., awake but relaxed with eyes closed. EEG Waves Frequency in HZ Amplitude in mV Location where it is best-recorded Alpha Rhythm 8-13 50-100 Parieto-occipital regions Beta Rhythm 13-30 5-10 Frontal region Theta Waves 4-8 200 Parietal and temporal regions in children Delta Waves 0.5-4 20-200 large amplitude Occipito-temporal Ref: Ganongs Review of Medical Physiology 25th edition Pgno: 272-273
