Mapping the Mind: Fruit Fly Connectome Revealed

This chapter explores a revolutionary research tool developed over 12 years that visualizes the connectome of a fruit fly's brain, known as the hemibrain, encompassing 25,000 neurons and 20 million synaptic connections. It highlights the technological advancements that enabled this complex mapping and discusses the implications for understanding brain function and behavior. The chapter also contrasts the challenges of mapping simpler organisms with the ambitious goal of elucidating the human connectome, addressing potential insights into conditions such as Alzheimer's disease.
