It was used to do not overcross many other parts of the map.\n \nOther remarks:\n1. State transitions were used to represent both state transition and migration.\n2. Empty compartments were placed to better visualized the brain anatomy.\n3. Unknown influence indicates coexpression.\n4. If specific brain developing time was available, it was included as a layer.\n5. If same reactions took place in additional compartments, names of those other compartments were included as a layer.',
