Knowledge about the clinical and electrical manifestations of parietal lobe
seizures is based mainly on case studies and occasional larger series (2,3,5,6,7,8,9).
As suggested by other studies, the parietal lobes
are considered to be the primary activated cortex when manipulating mental images, including those used during MRT performance (Cohen et al.
MIH Degree of Posterior prosencephalon frontal and non-separation parietal lobe
By analysing the brain responses during the cue and problems separately, the researchers found that for the highly math-anxious, there was a strong connection between math performance and activity in a network of brain areas in the frontal and parietal lobes
Earlier findings such as volumetric reductions in overall brain size, subcortical structures, the cerebellum, and parietal lobes
initially suggested that other brain regions were relatively spared.
001, especially in the prefrontal cortex, anterior cingulate gyrus, parietal lobes
, occipital lobes, and cerebellum (see Table 2 for specific areas of significant increases and Figure 1 for a visual representation of the areas of significant increase).
Recent structural and functional neuroimaging studies suggest a radically different, alternative understanding: neural networks may indeed involve the frontal, temporal and parietal lobes
to support a given higher-order cognitive function, for example working memory.
Hardan's group has found that among children aged 8-12 with autism, compared with healthy controls, increases in gray matter volume and total brain size may be explained by marked increases in total sulcal and gyral thicknesses in the cerebrum and temporal and parietal lobes
, but not in the frontal and occipital lobes.
He says "a nice little portion of the parietal lobes
were committed to parsing facial expressions, decoding the slightest nascent snarl.
Nicolelis' team reported in 2003 that the researchers had implanted electrodes in the frontal and parietal lobes
of the brains of two female rhesus monkeys that used a joystick to control a cursor on a computer screen.
The former showed a relatively more extended activation pattern in the frontal and parietal lobes
than in medial temporal areas, whereas the lower level chess-players showed a relatively opposite distribution.
Although Alzheimer's disease affects memory areas first, the parietal lobes
are a "close second," Dr.
