Multiple lines of evidence suggest the deployment of visuospatial attention is controlled by a frontoparietal network, with a right hemisphere dominance. Among cortical areas included in the network, the right posterior parietal cortex (PPC) has been proposed to be a crucial node and has also been implicated on clinical grounds. Here, the authors provide an overview of the existent literature giving evidence to a functional asymmetry of the parietal cortices in directing visuospatial attention, focusing on those studies seeking to characterize the causal role of PPC, applying transcranial magnetic stimulation and its combination with imaging techniques, such as electroencephalography and fMRI. First, the role of PPC and how this region exerts its control over remote areas of both hemispheres is discussed. The second part discusses studies involving neglect patients shedding light on the complex interplay between left and right PPC, strongly supporting the hemispheric rivalry theory. Finally, studies demonstrating changes of neglect disorders following the manipulation of the unaffected hemisphere activation will be discussed.<\/jats:p>","DOI":"10.1177\/1073858412447874","type":"journal-article","created":{"date-parts":[[2012,6,5]],"date-time":"2012-06-05T20:45:27Z","timestamp":1338929127000},"page":"208-217","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":26,"title":["To the Other Side of the Neglected Brain"],"prefix":"10.1177","volume":"19","author":[{"given":"Giacomo","family":"Koch","sequence":"first","affiliation":[{"name":"Laboratory of Clinical and Behavioural Neurology, Santa Lucia Foundation IRCCS, Rome, Italy"},{"name":"Stroke Unit, Policlinico Tor Vergata, Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Domenica","family":"Veniero","sequence":"additional","affiliation":[{"name":"Laboratory of Clinical and Behavioural Neurology, Santa Lucia Foundation IRCCS, Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlo","family":"Caltagirone","sequence":"additional","affiliation":[{"name":"Laboratory of Clinical and Behavioural Neurology, Santa Lucia Foundation IRCCS, Rome, Italy"},{"name":"Department of Neuroscience, University of Rome Tor Vergata, Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2012,6,4]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/01688639508405131"},{"key":"e_1_3_2_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0006-3495(94)80775-1"},{"key":"e_1_3_2_4_1","doi-asserted-by":"publisher","DOI":"10.1162\/jocn.1994.6.1.26"},{"key":"e_1_3_2_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00221-008-1601-8"},{"key":"e_1_3_2_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/cercor\/bhm159"},{"key":"e_1_3_2_7_1","doi-asserted-by":"crossref","unstructured":"Bisiach E Perani D Vallar G Berti A. 1986.
