In 1848, there was a railroad worker named Phineas Gage, who was severely injured on the job. In this essay, the author will discuss the details of the accident and what it revealed about how the different areas of the human brain support cognitive function. I will also discuss the characteristics of primary memory, the process of memory from perception and retrieval and the unreliability of memory retrieval.
Phineas gage is known as one of the most famous documented cases of brain injury. This brain injury occurred on September 13th, 1848 while Gage was working on the railroad excavating rocks with a tampering rod in the State of Vermont.

However, it was noted that around this time, Mr. Gage was considered to be suffering from some major changes in his personality.
What Phineas Gage’s Accident Reveals about Cognitive Functions
“Cognition refers to the higher order functions that are needed for learning and interacting with a person's environment. Each human brain is capable of multiple cognitive functions, such as memory, attention, executive functions and language. Each of the cognitive brain functions is highly interconnected, with an exchange of information between functions” (Stannard, 2010). When Phineas Gage's accident occurred, many people were skeptical because it was such a horrific accident, and it was hard to believe that anyone could survive an ordeal like that and lead any type of normal life. The accident occurred... [continues]
