Analysing EEG data with MATLAB. With an experiment including 30 subjects, 18 neutral 18 pleasent and 18 unpleasent photographs have been shown to each of the subjects with 6 sec gaps in 5 different frequences (alpha, theta, delta, gamma, beta) and eeg data collected with 16 channels. Each features have been extracted with different methods(wavelet energy, wavelet entropy, cross wavelet). I d like to take the statistical analyse emotion versus channel band and be able to say which frequency band and which electrode pair we can observe the most change.
