Child specific activation in left auditory cortex predicts behavioral performance in inhibition tasks
2020
Sensory processing during development is important for the emerging cognitive skills underlying goal-directed behavior. Yet, it is not known how auditory processing in children is related to their cognitive functions. Here, we utilized combined magneto- and electroencephalographic (M/EEG) measurements to show that child-unique auditory cortical activity at ∼250 ms after auditory stimulation predicts the performance in inhibition tasks. While unaffected by task demands, the amplitude of the left-hemisphere activation pattern was significantly correlated with the variability of behavioral response time. Since this activation pattern is not present in adults, our results suggest divergent brai…
Left hemisphere enhancement of auditory activation in language impaired children
2019
| openaire: EC/H2020/641652/EU//ChildBrain Specific language impairment (SLI) is a developmental disorder linked to deficient auditory processing. In this magnetoencephalography (MEG) study we investigated a specific prolonged auditory response (N250m) that has been reported predominantly in children and is associated with level of language skills. We recorded auditory responses evoked by sine-wave tones presented alternately to the right and left ear of 9–10-year-old children with SLI (n = 10) and children with typical language development (n = 10). Source analysis was used to isolate the N250m response in the left and right hemisphere. In children with language impairment left-hemisphere …

How salience enhances inhibitory control : An analysis of electro-cortical mechanisms
2023
Stop-signal tasks (SSTs) combined with human electro-cortical recordings (Event-Related Potentials, ERPs) have revealed mechanisms associated with successful stopping (relative to failed), presumably contributing to inhibitory control. The corresponding ERP signatures have been labeled stop N1 (+/- 100-ms latency), stop N2 (200 ms), and stop P3 (160–250 ms), and argued to reflect more sensory-specific (N1) versus more generic (N2, P3) mechanisms. However, stop N1 and stop N2, as well as latencies of stop-P3, appear to be quite inconsistent across studies. The present work addressed the possible influence of stop-signal salience, expecting high salience to induce clear stop N1s but reduced s…
Functional significance of auditory cortex activation for cognitive skills in children
2023
Lapsilla ja aikuisilla on huomattavia eroja aivojen kuuloinformaation käsittelyssä. Lasten aivoissa nähdään erityinen pitkäkestoinen aivovaste ~250 ms kuuloärsykkeen esittämisen jälkeen elektroenkefalografialla ja magnetoenkefalografialla (M/EEG) mitattuna. Kuulotiedon käsittelyn kehitys on lisäksi merkittävässä roolissa monien taitojen, kuten lukemisen, kirjoittamisen ja kielen oppimisen kannalta. Kuuloaivokuoren kehitys on viime aikoina yhdistetty myös laajemmin kognitiiviseen kehitykseen, mm. toiminnanohjaukseen ja tarkkaavuuteen. Tämänhetkisen tutkimuskirjallisuus osoittaa, että kuulotiedon käsittely erityisesti vasemmalla kuuloaivokuorella on yhteydessä suoriutumiseen kielellisissä teh…
