Embark on a journey into the labyrinth of the human brain with Genevra Hart, as she reveals the staggering complexity of our neural networks. Within the billions of dense microscopic neural connections that make up the brain, Hart isolates the importance of dopamine in controlling our thoughts and actions. Drawing from her research on decision-making, she illuminates the pivotal role of dopamine in refining our choices, and creating habits. With a focus on potential treatments for addictions, Hart advocates for advanced techniques such as deep brain stimulation. This exploration underscores the endless possibilities of neuroscience and its impact on our lives.
