"1 And he showed me a pure[a] river of water of life, clear as crystal, proceeding from the throne of God and of the Lamb. 2 In the middle of its street, and on either side of the river, was the tree of life, which bore twelve fruits, each tree yielding its fruit every month. The leaves of the tree were for the healing of the nations. 3 And there shall be no more curse, but the throne of God and of the Lamb shall be in it, and His servants shall serve Him. 4 They shall see His face, and His name shall be on their foreheads. 5 There shall be no night there: They need no lamp nor light of the sun, for the Lord God gives them light. And they shall reign forever and ever."

Research is constantly ongoing involving the pia mater. A group of hospitals in Madrid, Spain published an article in 2004 based on the ultrastructural finding in human spinal pia mater in relation to subarachnoid anesthesia. The group was researching whether or not fenestrations were present in the pia mater membrane, and the effect they have on the transfer of local anesthetics across the membrane. Based on their research, fenestrations were found at the thoracic-lumbar junction, the conus medullaris, and nerve root levels. Although proving the presence of fenestrations in certain regions involving the pia mater, the group concluded that they could not determine the significance behind these fenestrations. They speculated the fenestrations at the lumbar spinal level may in fact facilitate the movement of local anesthetics across the pia mater membrane, which could in turn affect the onset time and latency of a subarachnoid block. Although no officially conclusion was made, research is still being done to prove their speculation.[15]
