By contrast basement membranes are likely to be much less compressible and are likely to offer much greater resistance to flow (see [73, 100, 101]), thus precluding blood pressure variations as the driving force for perivascular flow (see next section). Diem et al. [100] have proposed vasomotion as an alternative. Pizzo et al. [16] have suggested that both basement membrane routes and other, extramural routes exist with their relative importance depending on the size of vessel and the size of the solute. Another proposed variation is a hybrid with an extramural basement membrane route mediating fluxes into the brain and an intramural basement membrane route between smooth muscle cells mediating fluxes outwards [88, 95].","tracks":[{"project":"MyTest","denotations":[{"id":"30340614-26463008-30705925","span":{"begin":360,"end":362},"obj":"26463008"},{"id":"30340614-28883786-30705926","span":{"begin":364,"end":367},"obj":"28883786"},{"id":"30340614-28883786-30705927","span":{"begin":494,"end":497},"obj":"28883786"},{"id":"30340614-29023798-30705928","span":{"begin":557,"end":559},"obj":"29023798"},{"id":"30340614-29754206-30705929","span":{"begin":948,"end":950},"obj":"29754206"},{"id":"30340614-26975356-30705930","span":{"begin":952,"end":954},"obj":"26975356"}],"namespaces":[{"prefix":"_base","uri":"https://www.uniprot.org/uniprot/testbase"},{"prefix":"UniProtKB","uri":"https://www.uniprot.org/uniprot/"},{"prefix":"uniprot","uri":"https://www.uniprot.org/uniprotkb/"}],"attributes":[{"subj":"30340614-26463008-30705925","pred":"source","obj":"MyTest"},{"subj":"30340614-28883786-30705926","pred":"source","obj":"MyTest"},{"subj":"30340614-28883786-30705927","pred":"source","obj":"MyTest"},{"subj":"30340614-29023798-30705928","pred":"source","obj":"MyTest"},{"subj":"30340614-29754206-30705929","pred":"source","obj":"MyTest"},{"subj":"30340614-26975356-30705930","pred":"source","obj":"MyTest"}]},{"project":"2_test","denotations":[{"id":"30340614-26463008-30705925","span":{"begin":360,"end":362},"obj":"26463008"},{"id":"30340614-28883786-30705926","span":{"begin":364,"end":367},"obj":"28883786"},{"id":"30340614-28883786-30705927","span":{"begin":494,"end":497},"obj":"28883786"},{"id":"30340614-29023798-30705928","span":{"begin":557,"end":559},"obj":"29023798"},{"id":"30340614-29754206-30705929","span":{"begin":948,"end":950},"obj":"29754206"},{"id":"30340614-26975356-30705930","span":{"begin":952,"end":954},"obj":"26975356"}],"attributes":[{"subj":"30340614-26463008-30705925","pred":"source","obj":"2_test"},{"subj":"30340614-28883786-30705926","pred":"source","obj":"2_test"},{"subj":"30340614-28883786-30705927","pred":"source","obj":"2_test"},{"subj":"30340614-29023798-30705928","pred":"source","obj":"2_test"},{"subj":"30340614-29754206-30705929","pred":"source","obj":"2_test"},{"subj":"30340614-26975356-30705930","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"MyTest","color":"#e9ec93","default":true},{"id":"2_test","color":"#d593ec"}]}]}}
