Overview
Brief Summary
The unique importance of human brain development during the first years of life is unquestionable. During an infant's first year, the brain undergoes its most dramatic structural and functional changes, with factors such as early social experience having a significant effect on this development. This study proposes to investigate changes in both brain and behavior across the first 12 months of life. At three time points (~3, 6, and 12 month), anatomical and diffusion magnetic resonance imaging (MRI), resting state functional magnetic resonance imaging (fMRI), electroencephalography (EEG), eye tracking, and observational data will be obtained from the same sample of infants. These measures will be used to track the development of important sensorimotor, socio-emotional, and cognitive skills and their underlying neural correlates, as well as investigate the effects of early social experience on specific aspects of this development

Outcomes
Primary Outcomes
Diffusivity
Time Frame: 9 months following the inclusion
Integrity of white matter fiber tracts assessed by DTI measures of the mean, radial, and axial diffusivity (mm2/s) along them.
Regional myelination
Time Frame: 9 months following the inclusion
Regional myelination assessed by T1 / T2 intensity ratios.
Fractional anisotropy
Time Frame: 9 months following the inclusion
Integrity of white matter fiber tracts assessed by DTI measures of the mean fractional anisotropy (0-1, where 0=isotropic diffusion, 1=diffusion restricted along one dimension) along them.
