Phineas P. Gage (1823–1860) was an American railroad construction foreman remembered for his improbable: 19 survival of an accident in which a large iron rod was driven completely through his head, destroying much of his brain's left frontal lobe, and for that injury's reported effects on his personality and behavior over the remaining 12 years of his life—effects sufficiently ...
He writes that the brain can stumble after injury, and the results can be serious. For example, if the visual cortex suffers damage, the person afflicted will lose many things, one of which being basic perceptual skills. Damage to the parietal lobe causes the loss of the ability to locate objects in space.
White matter fiber connections in DTI data are then drawn between these cortical regions and weighted by fractional anisotropy and strength of the connection. Such graphs have even been used to analyze the damage done to the famous traumatic brain injury patient Phineas Gage. [56]
The first case study on Phineas Gage's head injury is one of the most astonishing brain injuries in history. In 1848, Phineas Gage was paving way for a new railroad line when he encountered an accidental explosion of a tamping iron straight through his frontal lobe. Gage observed to be intellectually unaffected but exemplified post-injury ...
White matter refers to areas of the central nervous system (CNS) that are mainly made up of myelinated axons, also called tracts. [1] Long thought to be passive tissue, white matter affects learning and brain functions, modulating the distribution of action potentials , acting as a relay and coordinating communication between different brain ...
John Martyn Harlow (1819–1907) was an American physician primarily remembered for his attendance on brain-injury survivor Phineas Gage, and for his published reports on Gage's accident and subsequent history. Boston Herald, May 20, 1907. Harlow was born in Whitehall, New York on November 25, 1819 to Ransom and Annis Martyn Harlow. [1]
Lobes of the human brain with the frontal lobe shown in blue. Due to the difference in brain processing and function as well as various surface anatomy landmarks, the frontal lobes have traditionally been divided into two major areas known as the precentral cortex and prefrontal cortex. [citation needed]
The case of Phineas Gage was long considered exemplary of these symptoms, though more recent research has suggested that accounts of his personality change have been poorly evidenced. The frontal lobe is the same part of the brain that is responsible for executive functions such as planning for the future, judgment, decision-making skills ...
