How is that possible that we are so different? Why everyone reacts in other way for the same things? What defines our temperament?


These are the questions which since ancient times bother philiosophs, sages and casual people. Despite the fact that we are definitetly closer to the truth we also cannot admit that we know everything today about that matter. Things which today seem to be obvious used to be a topic of a long discussions and arguments. Role of our brain as a controler of emotions wasn't known for a really long time. In ancients times popular were many theories which seems bizzare today.
For example Hippocrates thought that our personality is affected by concentration of body fluids. He divided people into 4 personality types. Every type of personality depends on dominance of one fluid:

  • sanguine (łac. sanguis – blood)

  • choleric (gr. chole – bile)

  • melancholic (gr. mélanos – black + chole – bile)

  • phlegmatic (gr. phlegma)

But as time goes by the role of brain as a controler of emotion and also our personality became quite clear. Therefore brain is a complex organ with many parts of different use. How come that we know today that personality is placed in frontal lobes of our brain?
Here we come to the story of Phineas Gage. Man who isn't connected to medicine at all. A supervisor of railway, working in Vermont state of USA.

As many times before the progress was made by accident, this time this accident was almost fatal to Phineas. One of the things which Phineas did during his job was planting an explosives, which were put into holes in the ground and then tamped down with metal bar. 13 september 1948 during this activity occured and accident. Payload exploded while Phineas was tamping it with metal bar.As a consequence of explosion metal bar pierced trough face and frontal lobes of Phineas Gage and then flew 30 meteres from the place of an accident. This kind of accident usally means death in couple seconds but somehow this time was different. Phineas after few minutes regained consciousness and was awake during his journey to local doctor that took almost an hour. Physician said that Mr. Gage this day was in stable state and his pupils were reacting to light. After short recovery Phineas Gage returned to his job on railway.

Altough after this short break person who returned to job wasn't alike to Phineas at all! Phineas Gage used to be known as calm, patient and kind person but after accident he changed to hot-tempered and agressive person. Because of that he lost his job and spend rest of his life looking for his place and working in many different profesions. He even worked as an attraction in circus.

Becouse of its specularity case of Phineas Gage was documented by physycians and we can say that it was first documented case of Frontal Lobe Disorder.
