Atypical brain lateralisation in the auditory cortex and language performance in 3- to 7-year-old children with high-functioning autism spectrum disorder: a child-customised magnetoencephalography (MEG) study / Yuko YOSHIMURA in Molecular Autism, (October 2013)  

Public ISBD [article]  inMolecular Autism > (October 2013) Titre : Atypical brain lateralisation in the auditory cortex and language performance in 3- to 7-year-old children with high-functioning autism spectrum disorder: a child-customised magnetoencephalography (MEG) study Type de document : texte imprimé Auteurs : Yuko YOSHIMURA, Auteur ; Mitsuru KIKUCHI, Auteur ; Kiyomi SHITAMICHI, Auteur ; Sanae UENO, Auteur ; Toshio MUNESUE, Auteur ; Yasuki ONO, Auteur ; Tsunehisa TSUBOKAWA, Auteur ; Yasuhiro HARUTA, Auteur ; Manabu OI, Auteur ; Yo NIIDA, Auteur ; Gerard REMIJN, Auteur ; Tsutomu TAKAHASHI, Auteur ; Michio SUZUKI, Auteur ; Haruhiro HIGASHIDA, Auteur ; Yoshio MINABE, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Magnetoencephalography (MEG) is used to measure the auditory evoked magnetic field (AEF), which reflects language-related performance. In young children, however, the simultaneous quantification of the bilateral auditory-evoked response during binaural hearing is difficult using conventional adult-sized MEG systems. Recently, a child-customised MEG device has facilitated the acquisition of bi-hemispheric recordings, even in young children. Using the child-customised MEG device, we previously reported that language-related performance was reflected in the strength of the early component (P50m) of the auditory evoked magnetic field (AEF) in typically developing (TD) young children (2 to 5 years old) [Eur J Neurosci 2012, 35:644-650]. The aim of this study was to investigate how this neurophysiological index in each hemisphere is correlated with language performance in autism spectrum disorder (ASD) and TD children. We used magnetoencephalography (MEG) to measure the auditory evoked magnetic field (AEF), which reflects language-related performance. We investigated the P50m that is evoked by voice stimuli (/ne/) bilaterally in 33 young children (3 to 7 years old) with ASD and in 30 young children who were typically developing (TD). The children were matched according to their age (in months) and gender. Most of the children with ASD were high-functioning subjects. The results showed that the children with ASD exhibited significantly less leftward lateralisation in their P50m intensity compared with the TD children. Furthermore, the results of a multiple regression analysis indicated that a shorter P50m latency in both hemispheres was specifically correlated with higher language-related performance in the TD children, whereas this latency was not correlated with non-verbal cognitive performance or chronological age. The children with ASD did not show any correlation between P50m latency and language-related performance; instead, increasing chronological age was a significant predictor of shorter P50m latency in the right hemisphere. Using a child-customised MEG device, we studied the P50m component that was evoked through binaural human voice stimuli in young ASD and TD children to examine differences in auditory cortex function that are associated with language development. Our results suggest that there is atypical brain function in the auditory cortex in young children with ASD, regardless of language development.

Atypical development of the central auditory system in young children with Autism spectrum disorder / Yuko YOSHIMURA in Autism Research, 9-11 (November 2016)  

Public ISBD [article]  inAutism Research > 9-11 (November 2016) . - p.1216-1226 Titre : Atypical development of the central auditory system in young children with Autism spectrum disorder Type de document : texte imprimé Auteurs : Yuko YOSHIMURA, Auteur ; Mitsuru KIKUCHI, Auteur ; Hirotoshi HIRAISHI, Auteur ; Chiaki HASEGAWA, Auteur ; Tetsuya TAKAHASHI, Auteur ; Gerard REMIJN, Auteur ; Manabu OI, Auteur ; Toshio MUNESUE, Auteur ; Haruhiro HIGASHIDA, Auteur ; Yoshio MINABE, Auteur ; Haruyuki KOJIMA, Auteur Article en page(s) : p.1216-1226 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  magnetoencephalography  P1m  young children Index. décimale : PER Périodiques Résumé : The P1m component of the auditory evoked magnetic field is the earliest cortical response associated with language acquisition. However, the growth curve of the P1m component is unknown in both typically developing (TD) and atypically developing children. The aim of this study is to clarify the developmental pattern of this component when evoked by binaural human voice stimulation using child-customized magnetoencephalography. A total of 35 young TD children (32–121 months of age) and 35 children with autism spectrum disorder (ASD) (38–111 months of age) participated in this study. This is the first report to demonstrate an inverted U-shaped growth curve for the P1m dipole intensity in the left hemisphere in TD children. In addition, our results revealed a more diversified age-related distribution of auditory brain responses in 3- to 9-year-old children with ASD. These results demonstrate the diversified growth curve of the P1m component in ASD during young childhood, which is a crucial period for first language acquisition.

Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : BACKGROUND:Axon-guidance proteins play a crucial role in brain development. As the dysfunction of axon-guidance signaling is thought to underlie the microstructural abnormalities of the brain in people with autism, we examined the postmortem brains of people with autism to identify any changes in the expression of axon-guidance proteins.RESULTS:The mRNA and protein expression of axon-guidance proteins, including ephrin (EFN)A4, eEFNB3, plexin (PLXN)A4, roundabout 2 (ROBO)2 and ROBO3, were examined in the anterior cingulate cortex and primary motor cortex of autistic brains (n = 8 and n = 7, respectively) and control brains (n = 13 and n = 8, respectively) using real-time reverse-transcriptase PCR (RT-PCR) and western blotting. Real-time RT-PCR revealed that the relative expression levels of EFNB3, PLXNA4A and ROBO2 were significantly lower in the autistic group than in the control group. The protein levels of these three genes were further analyzed by western blotting, which showed that the immunoreactive values for PLXNA4 and ROBO2, but not for EFNB3, were significantly reduced in the ACC of the autistic brains compared with control brains.CONCLUSIONS:In this study, we found decreased expression of axon-guidance proteins such as PLXNA4 and ROBO2 in the brains of people with autism, and suggest that dysfunctional axon-guidance protein expression may play an important role in the pathophysiology of autism.

We developed a job interview training program using an android robot. The job interview training program using an android robot consists the following three stages: (1) tele-operating an android robot and conversing with others through the android robot, (2) a face-to-face mock job interview with the android robot, and (3) feedback based on the mock job interview and nonverbal communication exercises using the android robot. The participants were randomly assigned to the following two groups: one group received a combined intervention with "interview guidance by teachers and job interview training program using an android robot" (n = 13), and the other group received an intervention with interview guidance by teachers alone (n = 16). Before and after the intervention, the participants in both groups underwent a mock job interview with a human interviewer, who provided outcome measurements of nonverbal communication, self-confidence, and salivary cortisol. After the training sessions, the participants who received the combined interview guidance by teachers and the job interview training program using an android robot intervention displayed improved nonverbal communication skills and self-confidence and had significantly lower levels of salivary cortisol than the participants who only received interview guidance by teachers. The job interview training program using an android robot improved various measures of job interview skills in individuals with autism spectrum disorder.
