The first recall includes 570,000 model year 2000 pickups and sport utility vehicles with a problem that could prevent air bags from working in frontal collisions.
The frontal feedback system works through frontal motor routines, or action schemes, manipulating the release and reconstruction of stored sensory memories in posterior sensory areas.
No differences in performance were found for working memory/concentration and frontal lobe functioning (F =0,15, n.s.; F =1,55, n.s).s
The neuropsychological test scores were converted to Z-scores (standard equivalents) and single test values covering the same neuropsychological faculty were averaged to define the following factors: verbal learning/memory, visuo-spatial learning/memory, working memory/concentration and frontal lobe functioning.
"He's got the simmering cauldron that is his sexual deviance, but he's [also] got the good-working frontal lobe that allows him to hit the pause button".
This confirms our working hypothesis that frontal-to-parietal top-down causal streams along the DAN are exclusively mediated by orienting and they do not occur during less-attentive states.
These higher order functions allow the planning, recruitment and organization of other cognitive processes by means of initiation, modulation and inhibitory mechanisms, and participate in processes as working memory, selective attention (frontal-parietal network) and language (frontal-temporal network).
In magnetic resonance spectroscopy (MRS) and diffusion tensor imaging (DTI) studies, maturation of relatively restricted regions of white matter has been found to correlate with the development of cognitive functions such as working memory capacity (left frontal regions), reading ability (left temporal lobe) and even with IQ (bilateral association areas [ 144, 146].
Desmond and Fiez [ 98], by means of f-MRI, during a verbal working memory task showed that HVI and superior HVIIA cerebellar activations represent input from the articulatory control system of working memory from the frontal lobes, and that HVIIB activation is derived from the phonological store in temporal and parietal regions.
Examination of cerebral blood flow changes associated with pitch naming minus baseline in the AP automatic template group confirmed the same significant activation peak in the posterior extent of the left superior temporal gyrus (−61, −31, 5) with no associated changes in right frontal pitch working memory structures.
One such study found that when the difficulty of a working memory task increased, corresponding frontal theta power increases were associated with increased deactivation of BOLD response in medial frontal regions, PCC/precuneus and other DMN regions [39].
