PSYC04H3 Lecture Notes - Lecture 5: Analytic Signal, Spectral Density Estimation, Neural Oscillation
Document Summary
Psyc04: neuroimaging lab: extensive literature in which to contextualize and interpret your results, provide a quick and useful data quality check of single-subject data. Information contained in eeg data may have no representation in the erp: simulated data showing that complex and multifrequency information contained in eeg data may have no representation in the. Erp, if that information is non- phase-locked: one hundred trials were simulated, panels a and b show example trials, panel c shows the erp of those. 100 trials: panel d shows the time-frequency power. If you look closely, you can also see small but nonzero power at many frequencies for the stationary time series. Psyc04: neuroimaging lab: fourier"s theorem, several sine waves of differing amplitudes, frequencies, and phases, plotted separately (panel a) and after being added together (panel b) Psyc04: neuroimaging lab: event-related spectral perturbation (ersp): measures average dynamic changes in amplitude in the broad-band eeg frequency spectrum as a function of time.
