%0 Journal Article %T Gender Event-related Brain Oscillatory Differences in Normal Elderly Population EEG %A Stiliyan Georgiev %A Zlatogor Minchev %A Christina Christova %A Dolja Philipova %J International Journal Bioautomation %D 2011 %I Academic Publishing House %X In most of the scientific publications the data on gender related EEG differences is connected to exploration of disease or abuse-related changes and so takes the gender only as a cofactor. Although no one argues the fact, that gender is one of the greatest factors, influencing EEG results, there is a small number of papers discussing predominantly the gender influence on EEG. That is why the aim of this work is to try to examine the event-related oscillatory differences between a group of male and female individuals being a part of the normal elderly population. We calculated the Event-Related Potentials (ERPs) in time domain, the absolute Fourier power spectrum and S-transform for time-frequency analysis. The reaction times to auditory target stimuli were also calculated and compared. As a result of the present study we found that our female individuals have shown a significantly larger absolute theta and beta1 spectral power compared to male and having a larger N1 and higher P2 event-related potential components. In contrast to these, the male individuals have shown a stronger theta to beta coupling compared to the female individuals. %K Gender related EEG differences %K Event-related potentials %K EEG %K Brain oscillatory activity. %U http://www.clbme.bas.bg/bioautomation/2011/vol_15.1/files/15.1_04.pdf
