Get power values for EEG bands

Source: R/power_eeg_bands.R

Calculate power values for each of the EEG bands: Delta < 4 Theta >=4 and < 8 Alpha >= 8 and < 14 Beta >= 14 and < 32 Gamma >= 32 and < 50

power_eeg_bands(
  eeg_signal,
  sampling_frequency = 125,
  max_frequency = 32,
  num_sec_w = 5,
  aggreg_level = 6
)

Arguments

eeg_signal

EEG signal expressed in micro-Volts
sampling_frequency

Sampling frequency of the EEG signal. This is typically equal to 125Hz. Default value is 125.
max_frequency

The maximum frequency for which the spectrum is being calculated. Default value is 32.
num_sec_w

number of seconds in a time window used to obtain the Fourier coefficients. Typically, this number is 5
aggreg_level

number of 5 second intervals used to aggregate power. Typically, this number is 6 to ensure a 30 second interval window (standard in EEG analysis)

Value

List containing the aggregated power values for each EEG band
