Key Points

The central aim is to develop a mechanical model that explains how cerebrospinal fluid (CSF) circulation is influenced by various anatomical and physiological factors.
Developed a mechanical model incorporating anatomical asymmetries, respiratory mechanics, cardiac pulsation, and meningeal structures.
Defined state variable Psi along with indices T (torsion), Z (impedance), and C (systemic coherence).
Utilized existing 4D flow MRI datasets for future validation of the model.
The model identifies significant mechanical couplings affecting CSF flow with measurable roles from anatomical asymmetries and physiological mechanics.
Predictions made by the model are concrete and testable using current MRI data.

Abstract

Cerebrospinal fluid (CSF) circulation is governed bymechanically distributed couplings along the craniospinalaxis. This repository contains the complete mechanical modelof these dynamics. Anatomical asymmetries, respiratory mechanics, cardiacpulsation, and meningeal structures each play a defined andmeasurable role in organizing CSF flow. The model formalizesthese couplings through a state variable Psi and three derivedindices: T (torsion), Z (impedance), C (systemic coherence). No existing framework in the literature accounts for the fullset of mechanical couplings described here. The model makes concrete, testable predictions. Existing 4D flow MRI datasetsare sufficient to begin validation now. Author: Karl Julien Iai.Ach.
