All these damages caused to the brain have consequences for the conduct depending on several factors: the area of ​​the brain affected, the individual’s age and the time between the accident and the hospital intervention.

The origin of neuropsychology as a science

In prehistory, some humans ate the brains of others because they believed that this way they could feed on the intelligence of others. This early idea advanced significantly with the contributions of Hippocrates in the fourth century BC, who claimed that the brain was the seat of human intelligence.

Starting in the 19th century, some researchers observed some damaged brain structures and their intellectual limitation. These researches allowed establishing the relationship between the frontal lobe of the left hemisphere and the ability to speak. The link between language and brain anatomy was one of the first steps in neuropsychology understood until today.

The case of Phineas Gage and neuropsychology

In 1848, an American construction worker named Phineas Gage suffered an accident in which a metal bar passed through his skull. Despite this he did not die and went fully conscious to the doctor.

The accident had immediate consequences, especially fever and delusions for a few days. However, when he recovered from the accident, something unexpected happened: he went from being a kind and friendly individual to being impulsive and fickle. This sudden change in personality made him transform into a totally different person . Despite this, thanks to its accident and the consequences it produced, neuropsychology as a scientific discipline began to consolidate itself.
