Abstract
In this study, we introduce the EEG brain mapping technique based on the Duffing oscillator. For this purpose, we used EEG signals recorded from two musicians and two audience members in a music experiment. The Duffing oscillator was used to detect weak signals in the EEG signals. The frequency values of the weak signal were searched between 12 Hz and 37 Hz in all EEG channels of the participants. Then, topographical maps of the brain were generated according to the numbers of these weak signals detected. The results show that Duffing oscillator-based weak signal detection is a very effective tool for brain mapping. It shows that this method has great potential to help study various pathological conditions and understand the cognitive and behavioural functions of the human brain.
