Father of Neuroscience


Even though the origins of neuroscience can be traced back to the ancient Greeks, it remained a speculative science until the imaging of the neurons. The person who transformed the study of nerves to an experimental and observational science was Spanish physician Santiago Ramón y Cajal. Cajal’s images and drawings made such a profound contribution to the field of neuroscience that he is considered the Father of Neuroscience.

Cajal (1852-1935) created nearly 3000 drawings of the nervous system, detailing its architecture, and unraveling the mysteries of neuroanatomy. Through his elaborate drawings of the nervous system, he showed that the brain is made up of individual cells called neurons. Until Cajal’s drawings, the common view was that the nervous system was a spider web-like structure of cells that behaved like a single unit.

Although Cajal used the tissue staining method developed by his contemporary, Camillo Golgi, he and Golgi were adversaries who bitterly disagreed with each other's findings. Cajal used the same technique as Golgi and others but observed details that others could not. Cajal was a skilled artist with a sharp observation and a keen photographer, which helped him see things differently from others. His drawings are considered so accurate and detailed that they are used in classroom even today. Modern imaging technologies are said to still not be able to surpass his drawings in elegance and clarity.

Origin of the Word "Cancer"

In my previous post, I explored the history of cancer. Since we know it existed in ancient times, it follows that so did its name. In fact, the name "cancer" was coined by none other than the great Hippocrates (well, not the exact name but the root of the name). Hippocrates in fact, used two terms,  carcinoma and carcinos,  to describe ulcerous and non-ulcerous tumors respectively. He named the tumors after Carcinus (or Karkinos), a giant crab in Greek mythology that was sent by the Goddess Hera to help Hydra fight against Hercules. As to why Hippocrates chose to name the tumor after a crab is not quite clear but there are several theories:       -  The hardness of a malignant tumor reminded him of the hard shell of a crab.      - The pain induced by a malignant tumor is similar to a sharp pinch of a crab's claw.     -  The tenacity of cancer is similar to the determination with which a crab bites and grabs on to a person.  While all these theories seem plausible, the

Hippocrates: Father of Medicine

Another important person in Greek medicine is Hippocrates. Hippocrates is considered the father of modern medicine who continues to influence medicine more than 2000 years later. Although he is as revered as Asclepius, they have very different origins. While Asclepius is a mythological character, considered to be descended from God, Hippocrates is very much a historical figure, whose origin and life is recorded in history. Hippocrates lived from 460 to 375 BCE during the Classical Greece period and practiced medicine in Greece. His contribution to western medicine is rivaled by none other, and his collection of works covers almost every aspect of disease and medicine including infection, hygiene, epidemiology and the human immune system.

He was one of the first to separate religion from medicine, and sought to match treatment with symptoms.  His observations in the Corp

Meditrinalia: Festival of Health (AKA Wine!)

Happy Meditrinalia! Those who are legally allowed to, raise a glass of your favorite wine in cheer- the goddess of health is smiling upon you today! Meditrinalia is an ancient Roman festival that was celebrated on October 11 in honor of the goddess of medicine, Meditrina. According to legend, the festival marked the end of the vine harvest, and people of Latium began to taste their new wine on this day. Although it was first celebrated in honor of Jupiter, it soon gave rise to a new goddess of  healing/medicine, Meditrina, on whom the festival is now named.  The Romans made an offering of wine to the gods on this occasion while reciting   " vetus novum vinum bibo, novo veteri morbo medeor."   which translates to  ''Wine new and old I drink, of illness new and old I'm cured."  The new wine was thought to hold healing powers. Given that we now know wine is rich in antioxidants, and it can help reduce cholesterol and heart disease, the ancient Romans sure were o
