Concentrating on either the right or left ear stimulus significantly decreased activity bilaterally in the temporal lobes compared to concentrating on both ear stimuli, at the expense of an increased activation in the right posterior and inferior superior parietal lobeK.

The observed activations in the parietal lobe during the focused attention conditions could be part of a modality non-specific "attentional network"K. Hugdahl; Ian Law; S. Kyllingsbaek; K. Bronnick; Anders Gade; Olaf B. Paulson. Effects of attention on dichotic listening: an 15O-PET study. Human Brain Mapping 10(2):87-97, 2000. PMID: 10864233. WOBIB: 14.
Cortical activation converged to demonstrate bilateral core regions in the superior and inferior parietal lobe (centered on the intraparietal sulcus), which were similarly activated during all three mental rotation tasksK. Jordan; H. J. Heinze; K. Lutz; M. Kanowski; L. Jancke. Cortical activations during the mental rotation of different visual objects. NeuroImage 13(1):143-52, 2001. PMID: 11133317.

This reaction time effect was accompanied by increases in activity in four regions: the right ventrolateral prefrontal cortex, the supplementary motor area, the left superior parietal lobe, and the left anterior parietal cortexE. Hazeltine; Russell Poldrack; John D. E. Gabrieli. Neural activation during response competition. Journal of Cognitive Neuroscience 12(Supplement 2):118-29, 2000. PMID: 11506652. DOI: 10.1162/089892900563984. FMRIDCID: 2-2000-11173. WOBIB: 40.
Maintenance of orientations involved a distributed fronto-parietal network, that is, left and right lateral superior frontal sulcus (SFSl), bilateral ventrolateral prefrontal cortex (VLPFC), bilateral precuneus, and right superior parietal lobe (SPL)L. Cornette; P. Dupont; E. Salmon; G. A. Orban. The neural substrate of orientation working memory. Journal of Cognitive Neuroscience 13(6):813-28, 2001. PMID: 11564325. DOI: 10.1162/08989290152541476.

Our current understanding of spatial behaviour and parietal lobe function is largely based on the belief that spatial neglect in humans (a lack of awareness of space on the side of the body contralateral to a brain injury) is typically associated with lesions of the posterior parietal lobeHans-Otto Karnath; S. Ferber; M. Himmelbach. Spatial awareness is a function of the temporal not the posterior parietal lobe. Nature 411(6840):950-3, 2001. PMID: 11418859. DOI: 10.1038/35082075. WOBIB: 59.
Hence, the decisive phylogenetic transition from monkey to human brain seems to be a restriction of a formerly bilateral function to the right side, rather than a shift from the temporal to the parietal lobeHans-Otto Karnath; S. Ferber; M. Himmelbach. Spatial awareness is a function of the temporal not the posterior parietal lobe. Nature 411(6840):950-3, 2001. PMID: 11418859. DOI: 10.1038/35082075. WOBIB: 59.
The corresponding shape-color comparison showed extensive bilateral increases in rCBF in visual areas in the occipital and parietal lobes, including the primary visual cortexClaus Bundesen; Axel Larsen; Soren Kyllingsbaek; Olaf B. Paulson; Ian Law. Attentional effects in the visual pathways: a whole-brain PET study. Experimental Brain Research 147(3):394-406, 2002. PMID: 12428147. DOI: 10.1007/s00221-002-1243-1. WOBIB: 81.
Blood flow decreases did not generally show significant differences across the active task states within an experiment, but a verb-generation task produced larger decreases than a read task in right and left inferior parietal lobe (BA 40) and the posterior cingulate/precuneous (BA 31/7), while the read task produced larger decreases in left lateral inferior frontal cortex (BA 10/47)Gordon L. Shulman; Julie A. Fiez; Maurizio Corbetta; Randy L. Buckner; Francis M. Miezin; Marcus E. Raichle; Steven E. Petersen. Common Blood Flow Changes across Visual Tasks: II. Decreases in Cerebral Cortex.
