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 ...

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 .
White matter is the tissue through which messages pass between different areas of grey matter within the central nervous system. The white matter is white because of the fatty substance (myelin) that surrounds the nerve fibers (axons). This myelin is found in almost all long nerve fibers, and acts as an electrical insulation.
He noted that modularity is a matter of degrees, and that the brain is modular to the extent that it warrants studying it in regards to its functional specialization. [10] Although there are areas in the brain that are more specialized for cognitive processes than others, the nervous system also integrates and connects the information produced ...
Phineas Gage, who sustained a severe frontal lobe injury in 1848, has been called a case of dysexecutive syndrome. Gage's psychological changes are almost always exaggerated – of the symptoms listed, the only ones Gage can be said to have exhibited are "anger and frustration", slight memory impairment, and "difficulty in planning".

[8] [page needed] It may also be crucial to understanding traumatic brain injuries (as in the case of Phineas Gage) [9] and improving brain injury treatment. [10] [11] Following a series of meetings, the International Consortium for Brain Mapping (ICBM) evolved. [12] [page needed] The ultimate goal is to develop flexible computational brain ...
