Though research of the brain many things have been learn on how the brain functions and what parts of the brain hold the importance of cognitive functioning. Phineas Gage's accident was just the start of the learning process for the field of anatomy, biology and neuroscience to learn the brain and all of the functions and wonders of the human brain. Since, Phinaes life the research has been able to uncover the many miracles on how his life changed on that fatal day which changed his life forever.
The forebrain plays a significant part in cognitive functions. It is also the anterior

1848 an unforeseen accident happen when Phineas Gage was preparing an explosive hole that
required the use of a tamping iron. The tamper iron hit the rock causing a spark to ignited the
explosive power and sent the tamper iron though the cheek bone on the left side and exited
through the top of the head and into the air landing 30 feet away. How might this affect his
Phineas Gage would not know till months and years later what damage was done to his
brain and how it would affect his cognitive functioning. John Martin Harlow was the
attending physician that cleaned Gage's wounds by removing small bone fragments and
replaced the large fragments of the skull that remained but where displaced. He covered the
wound by placing straps on Gage's head and a wet... [continues]
