Parametric influences of incentive motivation on evoked responses were obtained during both the cue (Figure 1B) and target (Figure 1C) periods. In particular, our findings concerning reward-related sites are consistent with previous reports of parametric response increases in the nucleus accumbens (e.g., Knutson et al., 2005), caudate nucleus (Delgado et al., 2003) and orbitofrontal cortex (e.g., O'Doherty et al., 2001). Taken together, our observations revealed that parametric improvements in detection performance were accompanied by systematic modulations in three sets of brain regions that, together, support task performance, namely attentional, visual and reward-related regions.","tracks":[{"project":"0_colil","denotations":[{"id":"20859524-15888656-131718","span":{"begin":1058,"end":1062},"obj":"15888656"},{"id":"20859524-12822596-131719","span":{"begin":1098,"end":1102},"obj":"12822596"},{"id":"20859524-11135651-131720","span":{"begin":1154,"end":1158},"obj":"11135651"}],"attributes":[{"subj":"20859524-15888656-131718","pred":"source","obj":"0_colil"},{"subj":"20859524-12822596-131719","pred":"source","obj":"0_colil"},{"subj":"20859524-11135651-131720","pred":"source","obj":"0_colil"}]},{"project":"TEST0","denotations":[{"id":"20859524-178-186-131718","span":{"begin":1058,"end":1062},"obj":"[\"15888656\"]"},{"id":"20859524-218-226-131719","span":{"begin":1098,"end":1102},"obj":"[\"12822596\"]"},{"id":"20859524-235-243-131720","span":{"begin":1154,"end":1158},"obj":"[\"11135651\"]"}],"attributes":[{"subj":"20859524-178-186-131718","pred":"source","obj":"TEST0"},{"subj":"20859524-218-226-131719","pred":"source","obj":"TEST0"},{"subj":"20859524-235-243-131720","pred":"source","obj":"TEST0"}]},{"project":"2_test","denotations":[{"id":"20859524-15888656-38088799","span":{"begin":1058,"end":1062},"obj":"15888656"},{"id":"20859524-12822596-38088800","span":{"begin":1098,"end":1102},"obj":"12822596"},{"id":"20859524-11135651-38088801","span":{"begin":1154,"end":1158},"obj":"11135651"}],"attributes":[{"subj":"20859524-15888656-38088799","pred":"source","obj":"2_test"},{"subj":"20859524-12822596-38088800","pred":"source","obj":"2_test"},{"subj":"20859524-11135651-38088801","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"0_colil","color":"#b293ec","default":true},{"id":"TEST0","color":"#93ec98"},{"id":"2_test","color":"#ec93a7"}]}]}}
