Despite decades of research, the features of an input audio stimulus that are encoded in an
electroencephalogram (EEG) are still not clearly identified. We wish to investigate whether a
frequency-band coupling model that estimates the cortical neural activity from EEGs can
capture the important features of an input audio stimulus. To do so, EEG recordings were
acquired from 8 subjects during a listening task where the vowels a, i and u were randomly
presented. The neural activity was estimated from the EEG using a frequency-band coupling …
