This note provides an accessible introduction to key aspects of the mathematical modeling of brain fluid dynamics and solid mechanics in the context of brain glymphatics. We touch upon the different modes and cycles of brain pulsatility, the brain’s elastic properties, the brain’s fluid environment and fluid networks, and the chemical–mechanical interplay induced by osmotics, all under both physiological and pathological conditions.

摘要

This note provides an accessible introduction to key aspects of the mathematical modeling of brain fluid dynamics and solid mechanics in the context of brain glymphatics. We touch upon the different modes and cycles of brain pulsatility, the brain’s elastic properties, the brain’s fluid environment and fluid networks, and the chemical–mechanical interplay induced by osmotics, all under both physiological and pathological conditions.
