Abstract 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%.

[Departement_IRSTEA]Territoires [TR1_IRSTEA]DTAM; International audience; The ending of milk quotas marks a breach in the mode of milk supply management. Farmers and actors of territorial development are concerned about the future of dairy farming, since globally we can observe that local structures struggle to maintain themselves, and face a loss of autonomy and sovereignty in front of agro-industries. In this context a group of dairy farmers in the Chartreuse massif (French Northern Alps) wished to conduct a reflection on their future. It consisted in better understanding the territorial embeddedness of dairy value chains, compared with what could be done elsewhere (geographical perspective), and what has been done in the history of the area (historical perspective). We used a same reading grid based on six criteria relative to the geographic embeddedness of the value chains, the ability of the producers to specify their resources, and to organize themselves and be autonomous. Of the 18 initiatives analyzed concerning dairy products, we identified four types of territorial embeddedness. Producers have the best control when they are at the origin of the initiative and have invested in processing equipment. But this requires a lot of time and funding research, with a return on the milk price which is not immediate, time to amortize. The history of Chartreuse shows different trajectories of loss and gain of autonomy for the dairy producers, and a loss of collective. We discuss the cross-reading of these geographical and historical perspectives and their meanings for the Chartreuse producers.
