fMRI Study of Inhibitory Control

MRIT: An fMRI Study of Inhibitory Control was designed to examine children’s behavioral performance and brain activation during an inhibitory control task. The study involved data collection with a subsample of 9–13 year-old children who participated in a randomized efficacy trial of Treatment Foster Care of Oregon for Preschoolers (TFCO-P). The randomized efficacy trial of TFCO-P started with three groups of preschool-aged children: foster children who received the TFCO-P intervention, foster children who did not receive the TFCO-P intervention, and children who were not in foster care. This study investigated the long-term impact of early experiences and the TFCO-P intervention on the structure of specific brain regions assessed via magnetic resonance imaging (MRI), connections between specific brain regions assessed via diffusion tensor imaging (DTI), and activation of specific brain regions during an inhibitory control task via functional magnetic resonance imaging (fMRI).
