Why We Get Addicted

Why We Get Addicted is a self-paced learning path in Biological Sciences, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify the primary function of dopamine in human survival behavior; distinguish between natural evolutionary rewards and artificial chemical triggers; explain the role of the basal ganglia in routine formation.

Conductor

The Conductor

All aboard for a deep dive into the brain's reward circuitry. We explore the biological tracks that lead to dependency and the switches that govern our choices.

What you will learn

FOUNDATION

Establishes the core vocabulary and essential context you need before going further.
