On this essay I will attempt to describe the methods and techniques that biological psychologists use to study the brain and explain how these can help   to understand the relationship between brain and behaviour.
Our brain, spinal cord and peripheral nerves make up a system of integrated control and information processing. The scientific study of the brain and nervous system is called neuroscience or neurobiology. The brain is located inside the skull, is the main centre of regulation and control of body activities:   consciousness, thought, memory and emotion allowing this way human beings to identify, understand and interpret the world around them.
A most important basis of evidence between brain and behaviour is the study to brain injuries; one particular case is considered one of the most important scientific evidence suggesting that an injury to the frontal lobe of the brain could alter aspects of the personality, emotion and social interaction of the individuals, the case of Phineas Gage:
Phineas Gage was a young railroad construction worker in U.S. In 1848, he suffered an accident at work and he was pierced through the head by a tamping iron. Gage regained consciousness later and was taken to a local doctor, who assisted. Amazingly, he was talking and could walk. He not only survived the lesion, but also recovered well, physically.

He became extravagant and anti-social, and full mouth liar with bad manners, and could no longer stay in a job for a long time or plan for the future. "Gage was no longer Gage", his friends would say. (Wikipedia ,Phineas   Gage )
His skull was recovered and preserved and more recently, two Portuguese neurobiologists, Hanna and Antonio Damasio used graphic and brain imaging techniques to evaluate the likely course of the tamping iron through Gage's brain. They found that most of the damage must have...
