Sentences with phrase «medial frontal»

Cluster a (a) shows the default mode network, consisting of frontal regions, including superior frontal gyrus (BA 8/9) and medial frontal gyrus (BA 10/11) and precuneus / posterior cingulate cortex (BA 23/31) and bilateral regions overlapping middle / superior temporal tyrus (BA 21/39) and inferior / superior parietal cortex (BA 39/40).

These modules include the visual (yellow), sensory / motor (orange) and basal ganglia (red) cortices as well as the default mode network (precuneus / posterior cingulate, inferior parietal lobes, and medial frontal gyrus; maroon).

In comparison, the SI values of the medial frontal gyri were attenuated, indicating this region to be less consistently found in the DMN module.

However, for the sham acupuncture group, more differences were observed in contralateral operculum, ipsilateral insula, inferior frontal gyrus, medial frontal gyrus and superior frontal gyrus.

Two of such modules are the ventral (superior parietal cortex as well as superior and medial frontal gyri) and dorsal (superior parietal cortex, superior and dorsal lateral frontal, and precentral gyri) attention networks identified by previous fMRI analyses [3].

Recording from downstream neurons in the caudate and from thalamic neurons projecting to the medial frontal cortex indicated that this phenomenon originates within cortical networks.

Anatomically, these neurons have widespread connections to the brain stem, a primitive region that controls waking and sleep; to nearby basal ganglia involved in movement; and to the medial frontal lobes, which are involved in motivation.

Losses generated ERPs that originated deep within the medial frontal cortex, a part of the brain located behind the upper forehead.

«It might be that those medial frontal regions tell the rest of the brain, «You can chill,»» he says.

Moreover, researchers found that the aging brain's failure to coordinate deep - sleep brainwaves is most likely due to degradation or atrophy of the medial frontal cortex, a key region of the brain's frontal lobe that generates the deep, restorative slumber that we enjoy in our youth.

By employing two paradigms that differed widely in musical complexity, we found that improvisation (compared to production of over-learned musical sequences) was consistently characterized by a dissociated pattern of activity in the prefrontal cortex: extensive deactivation of dorsolateral prefrontal and lateral orbital regions with focal activation of the medial prefrontal (frontal polar) cortex.

Imaging studies using these composite measures of SES have found significant correlations between composite scores and regions in the medial temporal lobe and frontal lobe (Raizada et al., 2008; Jednoróg et al., 2012), but without knowing associations to specific SES markers, it is difficult to compare these studies with other structural imaging studies.
