In humans, we have learned about the many roles of the frontal lobe through brain damage and disease. A key figure in our knowledge about frontal lobe function is Phineas Gage, the railroad worker who had major frontal lobe damage due to a railroad accident. Phineas' sudden personality change...
Frontotemporal dementia (FTD) is a group of diseases that damage the frontal and temporal lobes of the brain. These lobes, located on the front and sides of your brain, are important for personality, behavior, and language, so FTD can cause symptoms beyond the loss of memory and thinking ab...
Outside of the test environment, those with frontal lobe damage often are adrift. While not limited to these, frontal lobe injury can clearly manifest itself in the following symptoms:Executive functioning deficits; Difficulties with complex processing; Mood and emotional changes, i.e. neurobehavioral...
The frontal lobe is an important part of emotional processing and has a wide range of neural connections with many brain regions (e.g., thalamus, cingulate cortex and hippocampus). Consequently, frontal lobe damage is more likely to cause mood disorders15. We selected patients with frontal lobe...
Damage here may result in difficulty attending to or a complete neglect of the contralateral side of space. Visuospatial and constructional deficits (such as in drawing, building small models, and so on) may be found on testing the patient with right-hemisphere parietal lobe damage. Temporal ...
have shown that unilateral damage in a dorsal frontoparietal network that provides top-down control of visual processing results in interhemispheric imbalance and leads to severe visuospatial bias towards the ipsilesional side, even leading to neglect of visual stimuli on the contralesional side6,20,21...
but preservation of temporal lobe auditory regions. Disordered speech output in nfvPPA is characterised by apraxia of speech and/or agrammatism35. In contrast to stroke aphasia the neural damage in frontal regions is partial36,37enabling us to study a disruption of predictive mechanisms, rather th...
What does the parietal lobe do? The primary sensory area of the brain is located in which lobe? 1. Which function will be lost due to damage of occipital lobe? (A) Hearing (B) Speech (C) Vision (D) Memory 2. Which centre is stimulated during an increas...
Five of six MF subjects showed some damage to the corpus callosum. Figure 3 shows tracings of coronal sections of the brains of the rats with MF lesions. DISCUSSION The results confirmed the view (Thomas, 1970) that lesions from 5% to 10% of the rat's cerebral cortex, -~hen - located...
(action observation, motor imagery) within the premotor cortex (PMC), the primary motor cortex (M1), and posterior parietal regions (inferior parietal lobe: IPL; superior parietal lobe: SPL) (Buccino et al., 2001; Ehrsson et al., 2003; Jastorff et al., 2010; Sakre...
