The needs that can be met in an area make the people of the area able to feel a product that comes from another area. Not only that, products from other regions will always tell their own story for the local community. So, every local community with other regional communities must be able to understand each other. Functional integration has several benefits that can be felt directly by the community. Therefore, the Aceh region needs quality tea from West Java so that the availability of tea in Aceh does not run out.
For the two hemispheres, functional integration refers to the interaction between specialized regions, enabling interhemispheric long-range synchronization and information flow (Friston, 2004; van den Heuvel and Sporns, 2013). Such functional integration has been found to play a vital role in cognitive processing, such as visuospatial attention, speech perception and creative thinking (Gotts et al., 2013; Nuttall et al., 2018; Chen et al., 2019). Rs-FC analyses to detect patterns of functional integration between the two brain hemispheres were firstly applied in the motor system (Biswal et al., 1995).
Combined with previous findings of the fundamental role of CC, HoFC under resting state might reflect the effect of CC on functional lateralization (Tzourio-Mazoyer et al., 2016). In fact, many studies have demonstrated the excitatory role of CC in interhemispheric processing (Galaburda et al., 1985, 1990). The CC may enforce cerebral processing integration between the left and right hemispheres (Lezak et al., 2004) and activate the unstimulated hemisphere (Yazgan et al., 1995). According to this hypothesis, more symmetric brains have stronger interhemispheric connections, indicating a correlation between a smaller CC and greater lateralization (Bloom and Hynd, 2005). In infant group, Emerson et al. (2016) tried to portray the development curve of interhemispheric functional asymmetry during the first 2 years of life, by leveraging a large sample of human infants with longitudinal rs-fMRI scans.
