Paradigm-dependent modulation of event-related fMRI activity evoked by the oddball task.
We have previously shown that event-related functional magnetic resonance imaging (ER-fMRI) may be used to record responses to the rapid, interleaved presentation of stimuli in the three-stimulus oddball task. The present study examined the sensitivity of ER-fMRI responses to variations in the range of inter-stimulus intervals (ISIs, calculated as the time from the offset of one stimulus to the...
متن کاملTemperament: an event-related potential study using the oddball paradigm
The present study examined the structure of interrelations between brain event-related potentials and behavioral measures and temperament dimensions during an attention task. Three temperament questionnaires were used: Eysenck Personality Inventory, Strelau Temperament Inventory, and Rusalov Structure of Temperament Questionnaire. Event-related potentials were recorded using the active auditory...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولCombined event-related fMRI and intracerebral ERP study of an auditory oddball task.
Event-related fMRI (efMRI) has been repeatedly used to seek the neural sources of endogenous event-related potentials (ERP). However, significant discrepancies exist between the efMRI data and the results of previously published intracranial ERP studies of oddball task. To evaluate the capacity of efMRI to define the sources of the P3 component of ERP within the human brain, both efMRI and intr...
متن کاملSource localization with MEG evoked by the olfactory oddball paradigm
1 Introduction Cortical areas activated by olfactory stimulation have not been made clear yet, though a few studies were reported [1-3]. We are trying to localize the sources of olfactory MEG. The olfactory response becomes quickly weak because of subject's habituation. Then the data for source localization have little number of averaging and include much noise. The estimation error of localiza...
