May 1, 1852 was born in Petilla de Aragón, Navarra, Santiago Ramón y Cajal, doctor and scientist.

On this day (May 1), 1852, Santiago Ramón y Cajal, doctor and scientist, was born in Petilla de Aragón, Navarra.
Santiago Ramón y Cajal studied medicine in Zaragoza, where his whole family moved in 1870. After graduating he was called up and served 3 years as a doctor in the first war for independence from Cuba.
Part of the savings from his stay in Cuba were the financial bases that allowed Cajal to acquire the microscope, a microtome, chemical reagents and dyes with which on his return he set up a modest laboratory in which he would begin histological investigations.
The year 1875 began his doctorate (which ended in 1877) and it was also the beginning of his scientific vocation. E n 1876, a guard assistant position and also took care of his father's private surgery patients, at the Nuestra Señora de Gracia Hospital in Zaragoza.
In 1887, he moved to Barcelona to occupy the chair of Histology created at the Faculty of Medicine of the University of Barcelona.
It was in 1888, defined by Cajal himself as his "peak year", when he discovered the mechanisms that govern morphology (discipline in charge of studying the structure of an organism ) and the connective processes of the nerve cells of the gray matter of the cerebrospinal nervous system.
Thanks to the detailed histological examinations of Ramón y Cajal, the synaptic cleft was discovered, a space of between 20 and 40 nanometers that separates the neurons; this gap suggested communication by chemical messengers traversing the cleft and allowing communication between neurons.
He proposed the existence of dendritic spines, a small protrusion on the membrane of the dendritic tree of certain neurons where, typically, synapses with an axonal bouton of another neuron, and in sometimes they contact several axons.
After creating excellent descriptions of neuronal structures and their connectivity, and providing detailed descriptions of cell types, he discovered a new cell type, the interstitial cell of Cajal (ICC ).
His work and contributions to neuroscience —disseminated in Europe by his friend the Swiss anatomist Rudolph Albert von Kölliker— were recognized in 1906 with the award of the Nobel Prize in Physiology or Medicine, an award that he shared with the Italian researcher Camillo Golgi, whose staining method (applied to microscope research) was applied by Ramón y Cajal for years, but with whose theses, curiously, , was not and never was in agreement.

he is frequently cited as the father of neuroscience .

One of his best-known phrases was:
«Sometimes we love each other because we know each other, and other times, perhaps more often, we love each other because we ignore each other».

- Where is Cajal?
- there
- where?
- there
- I don't see it
- well, it's right under your nose
-has he become invisible?
- but what do you say!? Here's the box!
- but what box!?
- didn't you want a box?
- nope! I want to know where Cajal is, Santiago Ramón y Cajal
- Oh! That Cajal!
- yes! That box! Oh my gosh!
-well he's in the bathroom, now he'll come
