Structural and functional maturation of the infant brain |
Magnetic Resonance Imaging scans will be performed with a 3 Tesla machine. Three-dimensional and diffusion sequences as well as functional MRI (fMRI) sequences will be performed in order to examine structural and functional maturation respectively. Structural sequences are used to study the different tissues of the brain; diffusion images give information about the connections of the brain (white matter) and fMRI gives information on how the brain integrates information to perform a specific function. |
At term age |
|
Secondary |
Maternal brain responsiveness |
The maternal brain responses will be evaluated by using structural and functional magnetic resonance imaging to measure structural changes on social, emotional and behavioural networks as well as the cerebral response of mothers viewing neutral, happy and distress face images of their own infant, along with a matched unknown infant. We will use a 3 Tesla machine. We will study cortical and subcortical networks related with the emotional, social and behavioral responses involving the mother-child interactions and responses, such as the insula, the cingulate cortex, the precentral gyrus, the right orbital gyrus, the inferior, middle and superior frontal gyrus the fusiform gyrus, supramarginal gyrus, the superior parietal gyrus, the inferior temporal gyrus, and basal ganglia among others. |
At 4 months |
