Table 1. Summary of the model equations obtained by writing the Kirchhoff current law at the circuit nodes.
| Kirchoff Current Laws | |
|---|---|
| Brain | |
| Compartment I | QA = QOA + QIC |
| Compartment C | QIC = QCB + QCS + QCF |
| Compartment S | QCS + QTS + QCvS = QSV |
| Compartment B | QFB + QCB = QBT |
| Compartment F | QCF = QFT + QFB |
| Compartment T | QFT + QBT = QTV + QTS |
| QV = QTV + QSV | |
| Eye | |
| Node 1 | QEye,In = Qcl + Qch + Qr |
| Node 2 | Qcl = Qcl,v + Juf |
| Node 3 | Qcl,v + Qch + Qr + Jtm = QEye,Out |
| Node 4 | Juf + Jsecr = Jah |
| Node 5 | Jah = Juv + Jtm |
| Body-Brain-Eye Coupling | |
| Ophthalmic Arteries | QOA = 2QEye,In |
| Cavernous Sinus | QCvS = 2QEye,Out |
