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 ...
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". [21]
This personality change is characteristic of damage to the frontal lobe, and was exemplified in the case of Phineas Gage. 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, attention span, and inhibition. These functions can decrease ...
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]
A classic example is Phineas Gage, who exhibited a change in behavior after one or both frontal lobes were destroyed by a large iron bar accidentally driven through his head (though Gage, despite conventional presentations of his case, did not exhibit the aggression, antisocial behavior, or loss of impulse control sometimes reported in patients ...
Connectograms have been used to monitor the progression of neurological recovery of patients who suffered a traumatic brain injury (TBI). [12] They have also been applied to famous patient Phineas Gage, to estimate damage to his neural network (as well as the damage at the cortical level—the primary focus of earlier studies on Gage). [13]
The most studied case of a brain lesion affecting the neuromoral network was that of Phineas Gage who suffered from damage to the ventromedial prefrontal cortex due to an accident. [28] The damage led Gage through a complete personality transformation that included the expression of socially inappropriate statements and lies towards his family ...
Also shown are the insular cortex (purple), the brain stem (black), and the cerebellum (blue). The frontal lobe of the human brain is both relatively large in mass and less restricted in movement than the posterior portion of the brain. [1] It is a component of the cerebral system, which supports goal directed behavior. [2]
