Phineas Gage Paper
The brain plays a significant role in cognitive functioning. The human brain is made up of various structures, and each of these structures is responsible for specific cognitive functions. Scientists and psychologists have conducted many studies and experiments in an effort to pinpoint which brain structures are responsible for certain cognitive functions. In the past, technology was quite limited which left few options for studying the human brain. The only way to study the brain at this point in time was to perform studies on subjects that were already deceased. While this did help shed some light on cognitive functioning there were still many unanswered questions and misunderstandings about the brain and its functions. One particular case that has been linked to the brains role in cognition is that of Phineas Gage. Gage suffered a traumatic brain injury which altered his original cognitive functioning abilities. The case of Phineas Gage has left a lasting mark on the world of cognitive psychology and has been used as a prime example of how the brain affects cognitive functioning. Cognitive Functioning

One important discovery was that the left and right hemisphere of the brain actually process information differently. Phineas Gage’s Life Changing Accident
