This chapter explores the concept of partial agenesis of the corpus callosum and its impact on social interaction and learning. It delves into the plastic processes in the brain that allow individuals to adapt, compares the presentation of individuals with partial agenesis to split brain subjects, and discusses the brain's ability to form alternative connections. Additionally, it highlights the importance of sensory stimulation in wiring the corpus callosum and suggests its potential for enhancing a child's development.
