Spatial cues - directing attention to external stimuli or to content in working memory - activate a network spanning from frontal eye fields, presupplementary motor cortex and anterior cingulate cortex, to the intraparietal sulcus, and the superior parietal lobule.
To ensure the faithful transmission of genomic sequences into RNA and daughter DNA, all living cells express lesion-specific surveillance factors that activate a network of signaling pathways to regulate DNA repair, the cell cycle, gene expression, differentiation, programmed cell death, and cell cell communications.
These proteolytic pathways activate a network of interconnected cell-signaling pathways that regulate cell proliferation, survival, migration and angiogenesis [6] [9].
This second task was originally chosen for its ability to activate a network of areas which are preferentially engaged when unexpected events occur and/or subjects are required to reorient attention [for a review see 32].
The mechanisms by which these chemicals alter THs involve up-regulation of hepatic catabolic enzymes (e.g., uridine diphosphate glucuronosyltransferases). 2,3,7,8-Tetrachlorodibenzo- p-dioxin (TCDD), dibenzofurans, and dioxin-like PCBs activate a network of phase II and III proteins via binding of the AhR (Schrenk 1998).
Third, emotional stimuli may activate a network of neural structures, including the amygdala, prefrontal and sensory cortices, which in turn modulate attention and visuo-perceptual processing, resulting in enhancement of the subjective perceptual experience of threat cues and their ability to capture attention (e.g., Davis & Whalen, 2001; Vuilleumier, 2005).
Researchers at Stanford University found that the main active component in royal jelly, a protein called royalactin, activates a network of genes that bolsters the ability of stem cells to renew themselves.
But this time he "turned on" the model, activating a network of computerized sensors.
Our task activated a network of brain regions including amygdala, orbital frontal gyrus, hippocampus, parietal gyrus, prefrontal cortex, and regions in the occipital cortex.
Nonphobic fear activated a network of threat-responsive brain regions and involved pupillary dilation, electrodermal response and self-reported affect selective to the attacking snakes.
The temporal conjunction task activated a network of areas including right superior parietal cortex and bilateral regions of intraparietal sulcus, frontal operculum and putamen.
