US EditionScientists Unveil Most Detailed Neural Map of a Mammalian Brain
- Neuroscientists produced the largest wiring diagram and functional map of a mammalian brain using a mouse's cerebral cortex, which is involved in vision.
- They analyzed a tissue sample containing over 200,000 cells, including roughly 84,000 neurons and about 524 million synaptic connections.
- This project utilized technologies that allow scientists to identify abnormal connectivity patterns linked to disorders.
- The openly shared data aims to unravel complex neural networks underlying cognition and behavior.

National Institutes of Health (NIH)…Scientists map unprecedented detail of connections and visual perception in the mouse brain
In a massive scientific effort, hundreds of researchers have helped to map the connections between hundreds of thousands of neurons in the mouse brain and then overlayed their firing patterns in response to visual stimuli. This breakthrough is a critical piece of foundational science to build toward understanding how our brains process visual information to reconstruct the images we see every day.
Scientists map miles of wiring in mouse brain
What happened Scientists Wednesday unveiled a functional 3-D map of the 84,000 neurons in a cubic millimeter of a mouse's brain, along with more than three miles of microscopic wiring — axons and smaller dendrites — and 523 million synapses connecting them.The massive dataset, published in the journal Nature, and color-coded rendering of how each neuron communicates, mark a big "step toward unraveling the mystery of how our brains work," The Ass…
