To investigate our region-specific hypotheses, we analysed the variations in brain activity associated with the digit and letter order tasks in the two groups within the bilateral superior parietal lobule (SPL) and horizontal portion of the intraparietal sulcus (HIPS) as well as the left angular gyrus (lAG).

The activation map for correct naming before therapy showed the recruitment of a large set of areas, including bilateral activation of the angular gyrus, superior parietal lobule, premotor cortex, left middle and inferior occipital gyri, and right cerebellum.
These analyses yielded clear age-related differences, with better discrimination within the right superior parietal lobule and cerebellum in young compared to that in older adults.
Of the (significantly) hyperfused regions, one is supplied by the MCA (the posterior supramarginal gyrus), three are supplied by the ACA (superior frontal gyrus, superior parietal lobule, and supplementary motor area), two are supplied by both the ACA and MCA (precentral and postcentral gyri, which are supplied by the ACA medially and the MCA laterally; our perfusion measures did not distinguish medial versus lateral aspects of these regions), and one is supplied by the PCA (superior lateral occipital cortex).
In responders, the superior parietal lobule, the intraparietal sulcus, and the posterior part of the temporal lobe tended to be spared, but not in nonresponders.
The former two (P5 and P8) sustained rather small lesions (19.7 and 44.1[cm.sup.3]; Table 1) which spared the superior parietal lobule, the intraparietal sulcus, and basal ganglia.
These regions included the bilateral insula, bilateral TPJ, bilateral dorsal ACC, right striatum, right superior fontal gyrus, left middle frontal gyrus, left superior parietal lobule, and left amygdala (Figure 3).
However, compared to the controls, the left cuneus, right precentral gyrus, and the bilateral middle-inferior occipital gyrus, lingual gyrus, and right superior parietal lobule significantly decreased ALFF in the pulsatile tinnitus patients.
(24) The group that was sensitive to discomfort glare had an increased BOLD response localised at three discrete bilateral cortical locations: in the cunei, the lingual gyri and in the superior parietal lobules.
Perception and learning of the patterns increased rCBF in V1 and 17 cortical fields located in the cuneus, the lingual, fusiform, inferior temporal, occipital, and angular gyri, the precuneus, and the posterior part of superior parietal lobules. In addition, rCBF increased in the anterior hippocampus, anterior cingulate gyrus, and in several fields in the prefrontal cortex.
Activations in inferior and superior parietal lobules for SWMT have been already reported in other studies [32].
