Brain

1700-2500 BC.

The early Greek philosophers, especially Aristotle, believed that the heart was the center of intelligence and thought. Later on, however, various philosophers and physicians from the time of ancient Greece began to describe the anatomy of the brain and its importance in the higher intellectual functions.

Galen, a famous Roman physician, advanced the ideas of the importance of the brain in higher intellectual functions and the function of nerves within the nervous system.

Galen’s Concept of the Organs and their Faculties

Heat plays a central role part in the theory of Galen. The three ‘faculties’ of the body are the nutritive, vital and logical faculties. The nutritive faculty is related to the stomach which “cooks” the food and converts it into chyle. The chyle is transported to the liver by the portal vein. In the liver further heat converts the food into blood and adds natural spirit. Some of the blood is transported via the veins to the heart where more heat is added to create vital spirit. The blood becomes thinner is distributed to the body by the arteries giving warmth and enables growth. The vital spirit is measured through the pulse. The brain adds psychic pneuma, which provides the rational and logical faculty in the form of thought will and choice. These are distributed to the body via the nerves. The logical faculty reigns supreme and is followed in orderof importance by the vital and nutrtive faculties. The transport systems of the body include the nerves which transmit the logical faculty, the arteries which transport the vital spirit, and the veins which transport the blood with nutritive faculty from the liver. Galen faculties of the body nutrition portal vein stomach liver vein heart vital faculty pneuma lungs brain logical faculty animal spirits

1700 – 1800

1700s and 1800s Physiology

Conductive properties of muscle and nerve were described by the scholalrly pursuits of Galvani, Dubois-Reymond, and Helmholtz. 

 Other important developments at this time include those in the area of histology. Through the work of people like Camillo Golgi, Schwann, Betz, Purkinje, and Cajal, the idea was put forth of the neuron being the fundamental anatomic structure and functional component of the nervous system. Since then, the advances in neuroscience have been tremendous. The work of people such as Sherrington in developing the term “synapse”, and others have been invaluable. Since then, others such as Freud and Pavlov, tried to understand the behavioral aspects of neuroscience. The contributions to the understanding of the pathology of neurological disease during this time period, by people such as Alois Alzheimer, and Eugen Bleuler, were noted. In 1909, the famous neurosurgeon, Harvey Cushing, was able to stimulate the human sensory cortex and Broadmann was able to characterize 52 different areas of cortical function. These early developments in neuroscience have been advanced tremendously over the last century. In areas or neuroanatomy, neurophysiology, and, recently, neuropharmacology, there have been tremendous advances in the understanding of this subject that continues to capture our attention. However, the field of neuroscience is still in its infancy, and we eagerly await new discoveries which may revolutionize our understanding of this exciting field

A set of documents, known as the Edwin Smith Surgical Papyrus, from the civilization of ancient Egypt is the earliest known written record of the brain. In it an unknown physician describes various brain injuries and treatments for those injuries. These papers are thought to be from the period between
