Little is understood about frontal lobe functions facilitating memory, but what is clear is that more in-depth research of brain injury patients is needed. Because most research compares those with brain injuries (whether frontal lobe or not) and those without, the scientific community is unsure whether certain memory impairment is specific to ...
Research shows that the most common areas to have focal lesions in non-penetrating traumatic brain injury are the orbitofrontal cortex (the lower surface of the frontal lobes) and the anterior temporal lobes, areas that are involved in social behavior, emotion regulation, olfaction, and decision-making, hence the common social/emotional and ...
Brain injury (BI) is the destruction or degeneration of brain cells.Brain injuries occur due to a wide range of internal and external factors. In general, brain damage refers to significant, undiscriminating trauma-induced damage.
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 ...
[7] [10] [11] Diffuse axonal injury is a key pathology in concussive brain injury. [5] The visual system may be affected. [12] [13] Contrecoup contusions are particularly common in the lower part of the frontal lobes and the front part of the temporal lobes. [4]
Frontal lobe disorder, also frontal lobe syndrome, is an impairment of the frontal lobe of the brain due to disease or frontal lobe injury. [5] The frontal lobe plays a key role in executive functions such as motivation, planning, social behaviour, and speech production.
Cerebral contusion (Latin: contusio cerebri), a form of traumatic brain injury, is a bruise of the brain tissue. [2] Like bruises in other tissues, cerebral contusion can be associated with multiple microhemorrhages, small blood vessel leaks into brain tissue. Contusion occurs in 20–30% of severe head injuries. [3]
The lobes of the brain most likely to be injured are the frontal and temporal lobes. [19] Other common locations for DAI include the white matter in the cerebral cortex, the superior cerebral peduncles, [16] basal ganglia, thalamus, and deep hemispheric nuclei.
