Socioeconomic Status and the Brain: Mechanistic Insights from Human and Animal Research

Human brain development occurs within a socioeconomic context and childhood socioeconomic status (SES) influences neural development particularly of the systems that subserve language and executive function. Research in humans and in animal models has implicated prenatal factors, parent-child interactions and cognitive stimulation in the home environment in the effects of SES on neural development. These findings provide a unique opportunity for understanding how environmental factors can lead to individual differences in brain development, and for improving the programmes and policies that are designed to alleviate SES-related disparities in mental health and academic achievement.
