Leonardo Da Vinci as a scientist
Behind every act of his life, even the most everyday (like watching the flight of a bird) was looking for a physical, mathematical or other explanation. It does not always hit, but many others. And with centuries ahead. During the winter of 1507-1508, Leonardo conducted a post-mortem dissection of an old centennial in the hospital of Santa Maria Nuova in Florence. This marked the beginning of five years of intense anatomical research. He attributed the death of that individual to a narrowing of the coronary arteries and, in parallel, provided the first clear description of atherosclerosis, a disease of the coronary arteries is now one of the most common causes of death in the Western world.
Working with human bodies in Florence allowed Leonardo to study the brain, as he had always wanted. Before that, the Renaissance artist had deduced the path of the sensory nerves and the brain studying how human skulls. He believed that acquiring knowledge was key to some of the issues I wanted to investigate, as the emotions and the nature of the senses, but no real brain to dissect the skulls alone could not provide that information. With corpses at your fingertips, Leonardo designed an ingenious experiment in which melted wax injected into the cerebral ventricles to find out what their true setting.
Da Vinci was able to understand some basic concepts about how our mind works. Among other things, he argued that "common sense (which resides in the brain) judges of the things that the other senses and transmit it into action by them. External objects sent to the five senses its images, which are transferred to the sensitivity and perception, and this common sense; and, after being examined here, they pass memory that retains more or less, depending on the power of each. " The article refers to woman who kept researching, Elena Sanz. More information on this topic in the number of very dedicated history to the biography of Leonardo Da Vinci.
