A research team from Princeton University in the United States, in collaboration with Korean researchers, has successfully completed a comprehensive map of the adult fruit fly brain. Their findings were published in a special issue of the international academic journal Nature.
The fruit fly brain contains a total of 139,255 neurons, which are connected by over 50 million synapses. These cells play a crucial role in controlling behaviors such as sensory perception, decision-making, and flight.
Notably, fruit flies share approximately 70% of their genes with humans, and about 75% of human genetic diseases have counterparts in fruit flies, underscoring the significance of this research.
Additionally, fruit flies exhibit human-like characteristics in various ways, such as aging and engaging in behaviors like mating.
In this study, the research team utilized AI technology and electron microscopy to slice the fruit fly brain into nanometer-thin sections to create 3D images. They then distinguished the cells and constructed a connectome. This process required massive amounts of data and precise analysis. The team employed a platform that allowed multiple researchers to work simultaneously on cell refinement, ultimately completing the brain map.
The completion of the adult fruit fly brain map is seen as a major milestone in neuroscience, offering valuable insights for the study of brain disorders like Alzheimer's disease and dementia.
