White Matter Microstructure and Atypical Visual Orienting in 7-Month-Olds at Risk for Autism

TLDR
Visual orienting latencies were longer in 7-month-old infants who expressed ASD symptoms at 25 months compared with both high-risk negative infants and low-risk infants, and abnormal functional specialization of posterior cortical circuits directly informs a novel model of ASD pathogenesis.
Abstract
Specific differences in visual orienting, critical in social-cognitive development, are associated with differences in white matter microstructure of the splenium.

On the emergence of autism: neuroimaging findings from birth to preschool

TL;DR: For example, this paper found evidence of increased cortical gray and white matter volumes, increased amygdala volumes, aberrant structural and functional connectivity, and atypical neurodevelopmental trajectories.

A statistical framework for the classification of infant DT images

TL;DR: A new adaptive atlas-based framework for the automated segmentation of different brain structures from infant diffusion tensor images (DTI) is introduced, constructed from a prior atlas database built using a subset of co-aligned training data sets that is adapted during the segmentation process guided by the visual appearance characteristics of several DTI features.

Heart rate-defined sustained attention in infants at risk for autism.

TL;DR: Heart rate-defined sustained attention served as a global biological measure of attention in high-risk infants, predicting greater variability in group risk status than behavioral looking alone and suggesting abnormal qualities of HRDSA may inform individual differences within this population.

Autism Diagnostic Interview-Revised: a revised version of a diagnostic interview for caregivers of individuals with possible pervasive developmental disorders

TL;DR: The revised interview has been reorganized, shortened, modified to be appropriate for children with mental ages from about 18 months into adulthood and linked to ICD-10 and DSM-IV criteria.

Neural Mechanisms of Selective Visual Attention

TL;DR: The two basic phenomena that define the problem of visual attention can be illustrated in a simple example and selectivity-the ability to filter out un­ wanted information is illustrated.

The Attention System of the Human Brain

TL;DR: Illustration de trois fonctions principales qui sont predominantes dans l'etude de l'intervention de l'sattention dans les processus cognitifs: 1) orientation vers des evenements sensoriels; 2) detection des signaux par processus focal; 3) maintenir la vigilance en etat d'alerte

Nonrigid registration using free-form deformations: application to breast MR images

TL;DR: The results clearly indicate that the proposed nonrigid registration algorithm is much better able to recover the motion and deformation of the breast than rigid or affine registration algorithms.
