[Eeglablist] Which is the best way to measure the "alpha" oscillation?

[장진원]

Hi all,

There have been long controversies on measuring alpha frequency power. Some
researchers (especially in clinical fields where electrical engineering is
not familiar) use frequency bands (8-12Hz or 8-13Hz) with FFT or Welch's
method to obtain spectral power. Other behavioral scientists prefer
subdivisions such as lower alpha band (8-10Hz) and higher alpha band
(10-12Hz). Recent advancement on FOOOF also enables the isolation of
periodic components to discover individual frequency peaks. There are
numerous other techniques that could specify the regions of eeg activities.
Which do you think is the best way to characterize the neurophysiological
activity often represented as "alpha" oscillation?
