Dream Activity Analysis in Low-number Electrode EEG: A Methodology Proposal

This study proposes a methodology for dream analysis based on frequency brain topography-mapping. Significant differences in normalised power spectra estimates between dream and non-dream experiences were found even when using only 19-channel EEG recordings. This approach includes only determined mathematical problems compared to the previously published inverse problem methodologies. It also offers the possibility to use a wider range of EEG recordings (from low electrode count to HD EEG).
