abstract = {Natural stimuli consist of multiple properties. However,
not all of these properties are equally relevant in a given
situation. In this study, we applied multivariate
classification algorithms to intracranial
electroencephalography data of human epilepsy patients
performing an auditory Stroop task. This allowed us to
identify neuronal representations of task-relevant and
irrelevant pitch and semantic information of spoken words in
a subset of patients. When properties were relevant,
representations could be detected after about 350ms after
stimulus onset. When irrelevant, the association with gamma
power differed for these properties. Patients with more
reliable representations of irrelevant pitch showed
increased gamma band activity (35-64Hz), suggesting that
attentional resources allow an increase in gamma power in
some but not all patients. This effect was not observed for
irrelevant semantics, possibly because the more automatic
processing of this property allowed for less variation in
free resources. Processing of different properties of the
same stimulus seems therefore to be dependent on the
characteristics of the property.},
