Music and speech listening enhance the recovery of early sensory processing after stroke.
Abstract Our surrounding auditory environment has a dramatic influence on the development of basic auditory and cognitive skills, but little is known about how it influences the recovery of these skills after neural damage. Here, we studied the long-term effects of daily music and speech listening on auditory sensory memory after middle cerebral artery (MCA) stroke. In the acute recovery phase, 60 patients who had middle cerebral artery stroke were randomly assigned to a music listening group, an audio book listening group, or a control group. Auditory sensory memory, as indexed by the magnetic MMN (MMNm) response to changes in sound frequency and duration, was measured 1 week (baseline), 3…
Tvåspråkighet och lärarskattade exekutiva funktioner samt prestationsbaserade kognitiva färdigheter hos elever i grundskolan
Ungdomar rör på sig allt mindre och endast 17 % av alla högstadieelever i Finland når upp till minimimängden en timmes fysisk aktivitet per dag. Tidigare forskning visar att det finns ett positivt samband mellan fysisk aktivitet och skolprestationer. I den här studien undersöker vi hur extrainsatt fysisk aktivitet inverkar på prestationer i matematik och arbetsminne över tid, samt om det finns någon skillnad mellan låg-, medeloch högpresterande elever. I studien deltog 129 finlandssvenska elever i årskurs 7 och interventionen pågick i tre månader. Eleverna delades in i en interventions- och en kontrollgrupp. På basis av av matematikprestationer delades eleverna in i låg-, medel- och högpres…
Amusia and Cognitive Deficits after Stroke
We studied the relationship between musical and cognitive deficits by testing middle cerebral arterial (MCA) stroke patients (n= 53) with a shortened version of the Montreal Battery of Evaluation of Amusia (MBEA) and an extensive neuropsychological test battery. Results showed that amusic patients (n= 32) had more severe cognitive deficits, especially in working memory and executive functioning, than did non-amusic patients (n= 21), and the severity of amusia also correlated with attention deficits. These findings thus suggest that domain-general attention, executive, and working memory processes are associated with amusia after stroke.
Cognitive deficits associated with acquired amusia after stroke: A neuropsychological follow-up study
Recent evidence on amusia suggests that our ability to perceive music might be based on the same neural resources that underlie other higher cognitive functions, such as speech perception and spatial processing. We studied the neural correlates of acquired amusia by performing extensive neuropsychological assessments on 53 stroke patients with a left or right hemisphere middle cerebral artery (MCA) stroke 1 week, 3 months, and 6 months after the stroke. In addition, structural magnetic resonance imaging (MRI) was performed on all patients 1 week and 6 months post-stroke. Based on their performance on a shortened version of the Montreal Battery of Evaluation of Amusia (MBEA), the patients we…
Auditory and Cognitive Deficits Associated with Acquired Amusia after Stroke: A Magnetoencephalography and Neuropsychological Follow-Up Study
Acquired amusia is a common disorder after damage to the middle cerebral artery (MCA) territory. However, its neurocognitive mechanisms, especially the relative contribution of perceptual and cognitive factors, are still unclear. We studied cognitive and auditory processing in the amusic brain by performing neuropsychological testing as well as magnetoencephalography (MEG) measurements of frequency and duration discrimination using magnetic mismatch negativity (MMNm) recordings. Fifty-three patients with a left (n = 24) or right (n = 29) hemisphere MCA stroke (MRI verified) were investigated 1 week, 3 months, and 6 months after the stroke. Amusia was evaluated using the Montreal Battery of …
Neurocognitive processing of auditorily and visually presented inflected words and pseudowords: Evidence from a morphologically rich language
The aim of the study was to investigate how the input modality affects the processing of a morphologically complex word. The processing of Finnish inflected vs. monomorphemic words and pseudowords was examined during a lexical decision task, using behavioral responses and event-related potentials. The stimuli were presented in two modalities, visually and auditorily, to two groups of participants. Half of the words and pseudowords carried a case-inflection. At the behavioral level, the inflected words elicited a processing cost with longer decision latencies and higher error rates. At the neural level, pseudowords elicited an N400 effect, which was more pronounced in the visual modality. In…
