EEG and Individual Alpha Frequency

For this task, I analyzed EEG recordings to identify each subject’s Individual Alpha Frequency (IAF). Using both FFT and Welch’s method, I estimated the power spectrum and compared results across approaches. The analysis showed that Welch’s method provided smoother and more reliable spectral estimates, making it preferable for identifying IAF. I concluded that accurate detection of IAF is essential for understanding individual differences in brain rhythms and their potential applications in cognitive neuroscience.
