| Summary: | Soybean is a grain product that has a lot of protein content. Bioactive peptides derived from soybean protein are believed to have the ability to maintain brain health such as the neurotransmitter system. Brain mapping is a mapping of the electrical activity of the brain to study the functional human brain. In this study, 2D brain mapping based on power spectrum is proposed to see the differences in brain activity in adolescents before and 1 h after consuming soy peptide using the 19-channel electroencephalogram. In the experiment, the adolescents in an age range of 16–24 years were involved (fasting in the span of 7–8 h before the experiment). The 2D brain mapping results showed that after consuming soy peptide, the subject as seen from alpha waves experienced an increase in activity by 5%.
