The Blue Brain project aims to create a digital reconstruction of the human brain by simulating neural circuits at a microscopic level. The initial phase involved modeling a small cubic millimeter of rat brain containing 10,000 neurons. Future phases will expand this to model larger sections of the rat brain and eventually the entire human brain through continued data collection, algorithm improvements, and increased computing power. The goal is to better understand brain function and emergent behaviors through observing interactions between simulated neurons.
