@viscera3d: The brain and its meninges constitute a dynamic hydromechanical system, where cyclic volume alterations are driven by arterial pulse pressure and cerebrospinal fluid (CSF) circulation. The 3D animation visualizes the microbiomechanics of the central nervous system within a cranial window. During the systolic phase, the pial arteries undergo radial expansion, propagating a pulse wave across the cerebral cortex. The brain tissue rhythmically expands, elastically elevating the translucent arachnoid maternal membrane. During diastole, an elastic recoil of the vasculature and parenchyma occurs. This continuous pumping mechanism drives adequate CSF exchange and cerebral perfusion within the enclosed cranial vault. #neurology #neurosurgery #anatomy #physiology #brain
