Fruit Fly’s Hemibrain 3-D Mapped For The First Time
The purpose of mapping the neurons in a fruit fly’s hemibrain is meant to show the effectiveness of the new technology used to map the brain just also determine the feasibility of mapping all the neurons in the human brain.
The fruit fly’s hemibrain has close to 25,000 neurons. The lead of the project, Gerry Rubin, was also responsible for mapping the fruit fly’s genome, which laid the foundation for the Human Genome Project, which sought to map to the human genome.
The entire brain of the fruit fly has nearly 100,000 neurons. Completing this task will be necessary towards developing the methods needed to map the 85 billion neurons in the human brain.
A fruit fly’s hemibrain is responsible for the ability to sleep and tell the time of day. Mapping the neurons was possible through a process of slicing the brain, and from these slices creating images. From that point, these images were pieced together to create a 3-D map outlining the network of neurons and synapses.
Google developed an artificial intelligence algorithm to shorten the process of mapping the hemibrain. It had to be trained by scientists to understand how to identify neurons and eventually learned to complete task in a short amount of time.
