nervous system
• despite hydrocephalus, mice exhibit normal ependymal cilia beat frequency and cerebral spinal fluid flow velocity relative to heterozygous controls
• no differences are noted in the distribution, number or structure of primary cilia in sections of the hippocampus CA1 region and dentate gyrus
• mice frequently exhibit a hydrocephalus phenotype ranging from mild ventricular distension to severe skull malformation
• injection of Evans blue dye into the lateral ventricle fails to stain the cerebral aqueduct and fourth ventricle, indicating a form of non-communicating (obstructive) hydrocephalus due to blockage of the cerebral aqueduct
• blockage of the cerebral aqueduct, as revealed by a lack of Evans blue dye
• enlargement of the lateral ventricles
• deformation (compression) of the hippocampus
• blockage of cerebrospinal fluid flow in the cerebral aqueduct
