To extract the alpha frequency band (8-12Hz) in EEGLAB, researchers can utilize spectral analysis techniques such as Fast Fourier Transform (FFT) or Wavelet Transform. First, preprocess the EEG data to remove artifacts and filter out noise. Then, apply the appropriate spectral analysis method to compute the power spectral density (PSD) of the EEG signals. Finally, extract the alpha band frequencies within the specified range (8-12Hz) and validate the results through visual inspection and statistical analysis to ensure the accuracy of the extracted signals.
