Digitized quantitative electroencephalographic patterns applied as magnetic fields inhibit melanoma cell proliferation in culture

► Digitized EEG patterns applied as magnetic fields slow cell growth. ► Specific brain patterns slowed melanoma cell growth in culture. ► Spectral power of effective pattern had predictable effects. ► Fine temporal structure of EM fields critical for biological effects. ► Effect evoked with weak intensities and one hour daily exposures.
