Cranio-spinal model and its electrical analogous circuit. The cranio-spinal model is divided into two compartments, cranium and spinal canal. The MR derived net transcranial blood flow QAV and CSF flow QCSF are used as input and output to the model, respectively. The lumped mechanical dampers or flow resistances in the cranial and spinal compartment are denoted by RC and RS respectively. The compliances of the cranium and spinal canal are denoted by CC and CS respectively. The inertial component of the CSF flow from the cranium into the spinal canal is denoted by LS
