| Research Abstract |
We compared fMRI signals between the arms crossed condition and the uncrossed condition, and found that the left posterior parietal cortex showed greater activations during the arms crossed condition than during the arms uncrossed condition. We then examined connectivity of the area to determine the functional anatomy of the arm crossing effect. The regions showing connectivity with the area overlapped with regions within the DMN but the area also showed connectivity with other brain areas including the anterior cingulate cortex. This finding may point to the area as a gateway connecting the DMN to the other neural regions.
