(FRAME-INFO (STRING "Cerebral Ventricles, Computer Reconstruction. The cerebral ventricles are seen in their correct position in this 3D reconstruction by rendering the overlying cortex translucent. The lateral ventricles are paired structures, parts of which lie in the frontal, parietal, occipital and temporal lobes. The interventricular foramen connects the lateral ventricles with the midline third ventricle. The cerebral aqueduct connects the third and fourth ventricles. From the fourth ventricle, cerebrospinal fluid \(CSF\) flows into the subarachnoid space via the paired lateral exit foramina and the median exit foramen \(not seen here as it is on the posterior surface\)."))
