Why is the story of Phineas Gage considered so extraordinary what does his story teach us about the brain?
What does his story teach us about the brain? The story about Phineas Gage is so extraordinary because he survived such a traumatic injury and a portion of his Frontal Lobe was removed. His story teaches us that the brain can still function even after a traumatic injury happens.

How did Phineas Gage’s accident change scientists understanding of the brain?
Gage didn’t die. But the tamping iron destroyed much of his brain’s left frontal lobe, and Gage’s once even-tempered personality changed dramatically. “He was the first case where you could say fairly definitely that injury to the brain produced some kind of change in personality,” Macmillan says.
What is the main function of the limbic system?
The limbic system is the part of the brain involved in our behavioural and emotional responses, especially when it comes to behaviours we need for survival: feeding, reproduction and caring for our young, and fight or flight responses.
Why the limbic system is important?
The limbic system is a network of structures located beneath the cerebral cortex. This system is important because it controls some behaviors that are essential to the life of all mammals (finding food, self-preservation). In humans, the limbic system is more involved in motivation and emotional behaviors.
What does Phineas Gage teach us about the brain?
Despite the exaggerated stories and fabrications, Gage taught us that complex functions such as decision-making and social cognition are largely dependent upon the frontal lobes. What does seem well established is that he managed to hold down several jobs in the years following his injury.
How was Phineas Gage’s personality changed?
Gage suffered a severe brain injury from an iron rod penetrating his skull, of which he miraculously survived. After the accident, Gage’s personality was said to have changed as a result of the damage the frontal lobe of his brain.
What did Phineas Gage’s injury prove about the brain?
What did researchers learn from Phineas Gage’s accident?
Summary: In 1848, Phineas Gage survived an accident that drove an iron rod through his head. Researchers, for the first time, used images of Gage’s skull combined with modern-day brain images to suggest there was extensive damage to the white matter “pathways” that connected various regions of his brain.
Why is the limbic system so important?
By helping the brain form new memories, the limbic system helps the body learn and remember information. It also plays a role in regulating cognitive attention. Research suggests, for example, that the cingulate gyrus focuses the brain’s attention on emotionally significant events.
