After a single exercise session, the researchers found in some individuals increased connectivity between the medial temporal, which surrounds the brain's memory center, the hippocampus, and the parietal cortex
and prefrontal cortex, two regions involved in cognition and memory.
Evidence from monkey neurophysiology shows that several brain locations are particularly involved in the interaction between the oculo-motor system and vision, namely: the frontal and supplementary eye fields in monkey frontal cortex, several portions of the parietal cortex
and motion sensitive areas.
In the cases in which the subjects report having seen the presented stimulus, it is observed that a sudden activation emerges that expands beyond local occipital sensory regions towards inferior bilateral frontal and dorsolateral regions, to the anterior cingulate cortex, and to the posterior parietal cortex
. In those cases in which the stimulus never becomes a content of consciousness, this activity is drastically reduced, and only a confined activation is observed in certain local brain regions that quickly begins to fade.
A recent review paper (Cabeza, Ciaramelli, Olson, & Moscovitch, 2008) examined the role of the parietal cortex
in episodic memory retrieval.
The most commonly used is the default mode network which involves the medial prefrontal cortex and the posterior cingulate cortex and lateral parietal cortex
. The default mode network performs only when the individual is in the resting state (1).
EEG caps can capture signals from all respective points of the brain such as occipital cortex, temporal cortex, parietal cortex
and frontal cortex.
They stimulate the premotor and parietal cortex
area in the brain - sensory movements in games that require real-time action - and the prefrontal lobe, which controls decision-making.
It is now clear that social brain function is mediated not only by structures originally proposed by the social brain hypothesis, (148) such as the amygdala, temporal cortex, and OFC, but also by many other regions including, but not limited to, the MPFC, DLPFC, PMv, and posterior parietal cortex
In the pre-instruction scans, parts of the brain associated with attention, working memory and problem solving--the lateral prefrontal cortex and parietal cortex
, sometimes called the brain's "central executive network--showed activity.
Similar to their gray-matter volume findings noted above, Pfefferbaum and colleagues noted that alcohol-consuming adolescents had thinner total, frontal, temporal, and cingulate cortices than nondrinkers; moreover, the number of binge drinking episodes in the past year was negatively associated with frontal and parietal cortex
The signature of AD in FDG-PET imaging is the involvement of posterior midline structures including precuneus and posterior cingulate cortex and parietal cortex
. This technique has a potential to predict conversion from mild cognitive impairment to AD with a sensitivity and specificity approaching to 80% (6).
One of those networks is the Default Mode Network (DMN) which is characterized by a network of brain structures that are more active in the absence of goal-directed behavior, namely: the lateral, inferior, and medial parietal cortex
; the medial frontal cortex (MFC); the posterior cingulate cortex along with the precuneus (PCC/pC); and the medial temporal cortex (Mazoyer et al., 2001; Raichle et al., 2001; Greicius, Krasnow, Reiss, & Menon, 2003; Mckiernan, Kaufman, Kucera-Thompson, & Binder, 2003; Buckner, Andrews-Hanna, & Schacter, 2008).
