Sentences with phrase «insular gyrus»

In women, the right side of the front insular gyrus was activated by the hand - grip exercise more than men, who instead had a greater left - side activation of the same region.

The research also sheds more light on the functions of the insular gyri.

Not exact matches

The insular cortex has five main parts called gyri serving different roles.

The researchers found that the portion of a brain region called the insular cortex (which is made up of gyri, or folds) showed differences in activity between men and women.

By contrast, females on average had higher density in the left frontal pole, and larger volumes in the right frontal pole, inferior and middle frontal gyri, pars triangularis, planum temporale / parietal operculum, anterior cingulate gyrus, insular cortex, and Heschl's gyrus; bilateral thalami and precuneus; the left parahippocampal gyrus, and lateral occipital cortex.

Specifically, males on average had larger volumes and higher tissue densities in the left amygdala, hippocampus, insular cortex, putamen; higher densities in the right VI lobe of the cerebellum and in the left claustrum; and larger volumes in the bilateral anterior parahippocampal gyri, posterior cingulate gyri, precuneus, temporal poles, and cerebellum, areas in the left posterior and anterior cingulate gyri, and in the right amygdala, hippocampus, and putamen.

By independently manipulating the grammaticality and auditory tonal working memory demands of nested atonal musical sequences, we found that grammatical violations of nested musical dependencies led to increased BOLD responses in the right inferior frontal gyrus (IFG) and bilateral anterior insular cortices (AIC), whilst increased auditory working memory demands led to enhanced responses in the bilateral middle frontal gyri (MFG) and inferior parietal lobules (IPL).

The contrast UNGRAMMATICAL > GRAMAMTICAL yielded significant clusters (red) in the right inferior frontal gyrus, right middle frontal gyrus, bilateral anterior insular cortices, the pre-supplementary motor area, and the right posterior middle temporal gyrus.

Using the refined model, activity was observed in the right pars opercularis, right pars triangularis, and bilateral anterior insular cortices for the contrast UNGRAMMATICAL > GRAMAMTICAL (seed regions in red), and the right middle frontal gyrus and right inferior parietal lobule for the contrast TWO - LoE > ONE - LoE (seed regions in blue).

Functional MRI (fMRI) studies employing similar violation paradigms have also reported differential responses in the bilateral inferior frontal gyri (sometimes with a right - hemispheric dominance) 18,22,23,24,25,26,27, and the anterior insular cortices22, 23,27.

For the main effect of GRAMMATICALITY (UNGRAMMATICAL > GRAMMATICAL), we found a cluster of increased BOLD response with maxima in the right inferior frontal gyrus (IFG; pars opercularis, triangularis, and orbitalis), right middle frontal gyrus (in the dorsolateral prefrontal cortex), and right anterior insular cortex (AIC).

Cluster e (e) shows a network of cingulate gyrus (BA 24) and bilateral insular and superior temporal gyrus (BA 13/22), a network that is also commonly found in resting - state studies.
