There was no difference in the recovery time of conditioned reflex activity as between dogs with frontal or parietal lobe injury. However, damage to the frontal lobes led to motor disturbances and prolonged motor excitation, and the animals moved about aimlessly. These effects were observed both ...
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...
Our experience leads us to assume that two factors are necessary for the development of status epilepticus; first extensive frontal lobe damage and secondly cerebral oedema. It is possible that cerebral oedema leads to status in patients with diffuse brain damage when it spreads into the centrum se...
Our hypothesis that frontal metabolism predicts cognitive course was derived from a conceptual model of subcortical IVD that emphasizes the important role of damage to subcortical frontal circuits in causing dementia. It may be that diminished frontal metabolism reflects progressive compromise of small ...
The lateral surface of the frontal lobe is indented by two sulci running in a broadly horizontal fashion, the superior and inferior frontal sulci. These demarcate the superior frontal gyrus (above the superior frontal sulcus), inferior frontal gyrus (below the inferior frontal sulcus), and middle...
To investigate which synaptic circuits mediate the transcallosal inhibition underlying unilateral cortical-damage-induced visuospatial bias, we first examined whether lesions of the medial and frontal cortices directly innervating the V1 in the mouse visual network induce visuospatial bias. We injected an...
Phineas Gage was also some of the first proof scientists had that the parts of our brains which maintain survival- things like consciousness and body function- and the parts that maintain our emotions and thoughts are different. I imagine it must have been, at that time, something like the ...
Similarly, virtual21and real lesion studies failed to validate an exact correspondence between language impairments and information represented in the frontotemporal speech network: damage in one area may, or may not, entail loss of function in the other, as even sub-regions within such well-known...
