This chapter presents an accessible description of the brain's architecture. It describes how the brain learns throughout life, giving an introduction to three key life phases: infancy and childhood, adolescence, and adulthood (including old
age). It also discusses how cognitive decline and the dysfunctions that come with ageing can be addressed and delayed through learning. It is especially useful for readers who have had no prior exposure to neuro‐scientific accounts of the brain, as the basic
principles and the subsequent analyses are aimed at the layperson, aided by figures and summary tables.
