Embryology History - Santiago Ramón y Cajal
Santiago Ramon y Cahal (1852 - 1934) and Camillo Golgi (1843 - 1926) jointly received the Nobel Prize in Medicine in 1906 "in recognition of their work on the structure of the nervous system."
A Spanish researcher who used then new histology Golgi staining techniques to identify the cerebellum cellular structure. His work was a turning point in our understanding of the structure of the brain, that until then had been described as a "syncytium" and not consisting of discrete cellular elements. For this research and other work on defining the structure of the brain he, along with Camillo Golgi (1843 - 1926), received the 1906 Nobel Prize in Medicine.

From the 1990 Science book review.
- "The neuroanatomist Santiago Ramon y Cahal might be considered something of a pioneer in the autobiographical genre, his straightforwardly titled Recuerdos de Mi Vida having appeared, in two volumes, in 1901 and 1907. The work was translated into English in 1937 and published as volume 8 of the Memoirs of the American Philosophical Society, itself now a long-standing sponsor of such works."

|Camillo Golgi (1843 - 1926) developed the histology silver staining technique, the basis of Cajal's study of the brain.
Golgi today though is best known for the cellular organelle that bears his name, the Golgi apparatus.

(CB) Ramon y Cajal originally identified these small (20-25 nm) nuclear membraneless organelles in cells, they have various suggested functions and are localized to the nucleolar periphery or within the nucleoli. They contain both newly assembled small nuclear ribonucleoproteins (snRNPs, for pre-mRNA splicing) and small nucleolar ribonucleoproteins (snoRNPs, for ribosomal RNA processing) particles. See also the review.
Proteins associated with two neural genetic abnormalities are associated with these bodies.
- Spinal muscular atrophy SMN1 (5q13) encodes a 38 kD protein located in Cajal bodies.
- Fragile X Syndrome protein (FMRP) isoforms 6 and 12 (ISO6 and 12) proteins located in Cajal bodies.  Fragile X Syndrome (FXS) is the most common form of inherited mental retardation and autism.
