![]() Decreased behavioural response to affective speech and reduced caregiver–child interactions are early signs of autism in infants. In contrast, its left counterpart undertakes a computational role in cognitive control function by connecting with more prefrontal, parietal, subcortical brain areas.Īffective speech, including motherese, captures an infant’s attention and enhances social, language and emotional development. Together, these results reveal a precise asymmetrical functional distribution of the cerebellum in bilingual language production, suggesting that the right cerebellum is more involved in language control. Furthermore, anodal tDCS over the right cerebellum significantly optimizes language control performance in bilinguals. ![]() Specifically, brain activation showed the bilateral posterolateral cerebellum was associated with bilingual language control, and an effective connectivity analysis built brain networks for the interaction between the cerebellum and the cerebral cortex. Here, using functional magnetic resonance imaging (fMRI) and transcranial direct current stimulation (tDCS), we revealed different functions of bilateral cerebellar lobules in bilingual language production. However, researchers have attempted to detail the comprehensive role of the cerebellum in several cognitive processes in recent years. The cognitive function of the human cerebellum could be characterized as enigmatic. These early-age brain alterations may be the result of dysregulation in multiple neural processes and stages and are promising prognostic biomarkers for future language ability. In summary, brain regions involved in language, social, and face processing were altered in ASD toddlers. Moreover, the identified brain alterations were related to ASD symptom severity and cognitive impairments at intake, and, remarkably, they improved the accuracy for predicting later language outcome beyond intake clinical and demographic variables. Most of these differences were replicated in an independent cohort of 38 ASD and 37 TD toddlers. Leveraging structural MRI data from 166 ASD and 109 typical developing (TD) toddlers and controlling for brain size, we found that, compared to TD, ASD toddlers showed larger or thicker lateral temporal regions smaller or thinner frontal lobe and midline structures larger callosal subregion volume and smaller cerebellum. ![]() Identifying prognostic early brain alterations is crucial for autism spectrum disorder (ASD). ![]()
