At this time, Ramón y Cajal was one of the most famous members of the scientific world and had received a large number of international distinctions and awards.
From 1905 to 1907, Ramón y Cajal focused on the analysis of the regeneration and degeneration of the nerves, and the central nervous paths.
Santiago Ramón y Cajal is one of the great figures of international medicine, a reference point for many contemporary researchers.

 Cajal
Cajal observed that neuroblasts are polarized in the sense that the site of the outgrowth of dendrites is opposite to that of the axons, and he established the general rule that dendrites differentiate later than the axon.
Ramon y Cajal fought all his life battles on two fronts: for contiguity and against continuity in the structure of the nervous system; and for protoplasmic outgrowth, against cell chains and plasmodesms, in the origin of the nerve fiber.
Cajal encountered here again the unsettled controversy between those who, beginning with Waller and Ranvier, postulated that the regenerated nerve is an outgrowth from the proximal stump, and the adherents of the Schwann cell chain and plastnodesm theories who brought forth the same arguments as in nerve fiber origin in the embryo.

Nobel Laureate (Medicine, 1906) Santiago Ramón y Cajal was born on March 1, 1852, at Petilla in Aragon, Spain.
Cajal's studies on the structure of the cortex of the brain have been partly grouped together and translated into German by J. Bresler, 1900-1901.
Cajal is also the author of Reglas y Consejos sobre Investigacion Cientifica (Rules and advices on scientific investigation), which appeared in six Spanish editions and was translated into German (1933).

Santiago Ramón y Cajal was born in May 1852 in the village of Petilla, in the region of Aragon in northeast Spain.
Cajal was a rebellious teenager, and his father apprenticed him for a while to a shoemaker and to a barber.
Cajal's opus provided the foundation of modern neuroanatomy, with a detailed description of nerve cell organization in the central and peripheral nervous system of many different animal species, and was illustrated by Cajal's renowned drawings, which for decades (and even nowadays) have been reproduced in neuroscience textbooks.

He was appointed manager of the Cajal Institute of Madrid and scholar of several institutions, such as the Medical Royal Academy of Zaragoza and Barcelona.

Cajal established the foundation of modern neuroanatomy, providing detailed descriptions of nerve cell organization in the central and peripheral nervous system.
In addition, Cajal defined "the law of dynamic polarization," stating that the nerve cells are polarized, receiving information on their cell bodies and dendrites and conducting information to distant locations through axons; this is a basic functional principle of neural connections.

Cajal received numerous prizes, honorary degrees and distinctions, but undoubtedly the most important was the Nobel Prize for Physiology or Medicine he received in 1906.
To describe the work of Cajal is a rather difficult task, because, unlike other great scientists, he is not known for one single discovery, but rather for his many and important contributions to our knowledge of the organization of the nervous system.
Cajal was introduced in 1887 to the Golgi method during a visit to the private laboratory of the well-known psychiatrist and neurologist Luis Simarro.

Cajal shared the Nobel Prize with Golgi in the same year, for his masterful interpretations of his preparations in which he applied the method of Golgi.
Cajal was not introduced to a scientific career under the direction of any scientist, as then usually occured with most scientists, but rather he became a prominent neurohistologist on his own.
The third phase of Cajal’s career began in 1903, with his discovery of the reduced silver nitrate method, and ended with his death in 1934; this period was devoted mainly to the investigation of traumatic degeneration and regeneration of the nervous system.

Bastero-Gil is a Ramón y Cajal scientist at the Department of Theoretical and Cosmos Physics at the University of Grenada, and President of the National Association of Ramón y Cajal Researchers (Asociación Nacional de Investigadores Ramón y Cajal, or ANIRC).
On paper the Ramón y Cajal was launched as a five-year contract whose final aim was to integrate young researchers into the Spanish system permanently, and to encourage the support of research centres.
As an example, of the 593 Ramón y Cajal contracts that were given within CSIC institutes in the first 4 years of the programme, "405 are still ongoing, 147 have permanent positions in CSIC centres, and 41 have quit or have positions at other research institutions, the private sector, etc.," says ANIRC Secretary Mira Obrador.

To commemorate Cajal’s birthday on 1 May 1852, in Petilla de Aragón (a small village of Navarra in the north of Spain), several medals were coined, two of the most significant are shown in Figures 2 and 3.
In these diverse articles, Cajal studied the organization of climbing fibers, the development of Purkinje neurons and of basket cell axons around their soma, the organization of the spinal cord and of the retina, all of which allowed to him to establish his neuronal theory.
During his Nobel ceremony discourse, Cajal showed many examples demonstrating the two fundamental concepts necessary to understand the function of the nervous system: the neuron theory and the law of polarity of neurons (that neurons are contiguous and that nerve impulses travel from the dendrites and soma to the nerve endings).
