Sixteen healthy male volunteers were tested twice 1 week apart, either after 24 hr of food deprivation or after normal food intake. ERPs were measured while participants viewed appetitive food pictures as well as standard emotional and neutral control pictures. Results show that the ERPs to food pictures in a hungry, rather than satiated, state were associated with enlarged positive potentials over posterior sensor sites in a time window of 170-310 ms poststimulus. Minimum-norm analysis suggests the enhanced processing of food cues primarily in occipito-temporo-parietal regions. In contrast, processing of standard emotional and neutral pictures was not modulated by food deprivation. Considered from the perspective of motivated attention, the selective change of food cue processing may reflect a state-dependent change in stimulus salience.</dcterms:abstract> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-25T09:24:42Z</dcterms:available> <dc:contributor>Hamm, Alfons O.</dc:contributor> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/11007"/> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103416863-3868037-7"/> <dcterms:title>Deprivation selectively modulates brain potentials to food pictures</dcterms:title> <dc:creator>Weike, Almut I.</dc:creator> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-25T09:24:42Z</dc:date> <dcterms:bibliographicCitation>First publ. in: Behavioral Neuroscience 122 (2008), 4, pp. 936-942</dcterms:bibliographicCitation> <dc:creator>Hamm, Alfons O.</dc:creator> <dc:contributor>Stockburger, Jessica</dc:contributor> <dc:creator>Stockburger, Jessica</dc:creator> <dc:creator>Schupp, Harald Thomas</dc:creator> <dc:language>eng</dc:language> <dc:contributor>Weike, Almut I.</dc:contributor> <dcterms:issued>2008</dcterms:issued> <dc:contributor>Schupp, Harald Thomas</dc:contributor> <dc:format>application/pdf</dc:format> </rdf:Description> </rdf:RDF>
