Brain responses to the same spoken syllable completing a Finnish word or a pseudo-word were studied. Native Finnish-speaking subjects were instructed to ignore the sound stimuli and watch a silent movie while the mismatch negativity (MMN), an automat

Background and Purpose— The determination of cerebral blood flow heterogeneity (FH) by dynamic susceptibility contrast (DSC) magnetic resonance imaging has recently been proposed as a tool to predict final infarct size in acute stroke. In this stud

Effects of noise from functional magnetic resonance imaging on auditory event-related potentials in working memory task

Autor: Irina Anourova, Risto Näätänen, Hannu J. Aronen, S. Martinkauppi, Nikolai Novitski, Synnöve Carlson

Publikováno v: NeuroImage. 20(2)

The effects of functional magnetic resonance imaging (fMRI) acoustic noise were investigated on the parameters of event-related responses (ERPs) elicited during auditory matching-to-sample location and pitch working memory tasks. Stimuli were tones w

Publikováno v: NeuroImage. 13(6 Pt 1)

The distribution of brain activation during working memory processing of emotional vocal expressions was studied using functional magnetic resonance imaging (fMRI) in eight female subjects performing n-back tasks with three load levels (0-back, 1-bac
