An Increase of the Central Frequency of Alpha Brain Wave Effected by Soy Peptide in Open Eyes Condition based EEG Signals

Soy Peptide is one of the grain plants that contains a lot of bioactive peptide protein. It is believed that the presence of bioactive peptides originating from soybean can maintain defense in the brain when there is interference with the neurotransmitter system. However, the potential protective effect caused by bioactive peptides derived from soybean has not been systematically studied. To understand the relationship of bioactive peptides to brain activity, an experiment in recording EEG signals using 17 subjects was conducted. This research was conducted with two methods, namely, open your eyes before consuming soy peptide (pre) and open eyes after consuming soy peptide (pre). Data is recorded and obtained using the WinEEG application and assisted by the bandpass filter. From the experimental results found an increase in the frequency central of alpha brain wave with an average of 2% after consuming soy peptide.
