Selective attention to sound location or pitch studied with event-related brain potentials and magnetic fields

Autor: Teemu Rinne, Kimmo Alho, Anna-Kaisa Särkkä, Alexander Degerman, Juha Salmi

Publikováno v: European Journal of Neuroscience. 27:3329-3341

Event-related brain potentials (ERPs) and magnetic fields (ERFs) were used to compare brain activity associated with selective attention to sound location or pitch in humans. Sixteen healthy adults participated in the ERP experiment, and 11 adults in

Two separate mechanisms underlie auditory change detection and involuntary control of attention

Autor: Anna Särkkä, Alexander Degerman, Teemu Rinne, Kimmo Alho, Erich Schröger

Publikováno v: Brain Research. 1077:135-143

We used behavioral and event-related potential (ERP) measures to study the neural mechanisms of involuntary attention switching to changes in unattended sounds. Our subjects discriminated two equiprobable sounds differing in frequency (fundamental fr

Distributed cortical networks for focused auditory attention and distraction

Autor: Teemu Rinne, Kimmo Alho, Siiri Kirjavainen, Alexander Degerman, David L. Woods, Oili Salonen, Xiaojian Kang

We used behavioral measures and functional magnetic resonance imaging (fMRI) to study the effects of parametrically varied task-irrelevant pitch changes in attended sounds on loudness-discrimination performance and brain activity in cortical surface

Orienting and maintenance of spatial attention in audition and vision: multimodal and modality-specific brain activations

Autor: Juha Salmi, Teemu Rinne, Kimmo Alho, Oili Salonen, Alexander Degerman

Publikováno v: Brain structurefunction. 212(2)

We studied orienting and maintenance of spatial attention in audition and vision. Functional magnetic resonance imaging (fMRI) in nine healthy subjects revealed activations in the same superior and inferior parietal, and posterior prefrontal areas in

Human brain activity associated with audiovisual perception and attention

Autor: Johanna Pekkola, Mikko Sams, Alexander Degerman, Iiro P. Jääskeläinen, Teemu Rinne, Kimmo Alho, Taina Autti

Publikováno v: NeuroImage. 34(4)

Coherent perception of objects in our environment often requires perceptual integration of auditory and visual information. Recent behavioral data suggest that audiovisual integration depends on attention. The current study investigated the neural ba

Selective attention to sound location or pitch studied with fMRI

Autor: Oili Salonen, Alexander Degerman, Teemu Rinne, Kimmo Alho, Juha Salmi

Publikováno v: Brain research. 1077(1)

We used 3-T functional magnetic resonance imaging to compare the brain mechanisms underlying selective attention to sound location and pitch. In different tasks, the subjects (N = 10) attended to a designated sound location or pitch or to pictures pr

Modulation of auditory cortex activation by sound presentation rate and attention

Autor: Teemu Rinne, Kimmo Alho, Alexander Degerman, Mikko Sams, Johanna Pekkola, Iiro P. Jääskeläinen, Taina Autti

Publikováno v: Hum Brain Mapp

We studied the effects of sound presentation rate and attention on auditory supratemporal cortex (STC) activation in 12 healthy adults using functional magnetic resonance imaging (fMRI) at 3 T. The sounds (200 ms in duration) were presented at steady

Superior temporal and inferior frontal cortices are activated by infrequent sound duration decrements: an fMRI study

Autor: Teemu Rinne, Kimmo Alho, T Alexander Degerman

Publikováno v: NeuroImage. 26(1)

Functional magnetic resonance imaging (fMRI) was used to examine the processing of infrequent changes occurring in an unattended sound sequence. In event-related brain potentials (ERPs), such sound changes typically elicit several responses, includin

Spectral and temporal stimulus characteristics in the processing of abstract auditory features

Autor: Petri Paavilainen, Rika Takegata, Alexander Degerman, István Winkler

Publikováno v: Neuroreport. 14(5)

The processing of abstract stimulus features in the human brain was studied by presenting the subjects with frequent standard tone pairs and infrequent deviant tone pairs. Both pairs varied randomly over a wide frequency and/or intensity range, there
