From a cubic millimeter of tissue, scientists constructed a precise, 3D map of the activity in a mouse’s brain, detailing 84,000 neurons and more than 500 million synapses.

Scientists say the map of a speck of a mouse's brain could be as transformative as the Human Genome Project. Here's what to know. Hotspots ranked Start the day smarter ☀️ Funniest cap messages ...

Scientists achieved “a milestone” by charting the activity and structure of 200,000 cells in a mouse brain and their 523 million connections.

Researchers are already hard at work on a connectome of a mouse brain, which has about 1,000 times more neurons than the brain of a fruit fly. Read more of science correspondent Jon Hamilton 's ...

But now, an international team of scientists has created the first map showing every neuron and connection in an adult brain.

With such a detailed and functional brain map now available to study, the implications of this work are vast. By studying how these networks function under natural conditions, ...

A map of part of a mouse brain, which is expected to be generalisable to people, could help scientists understand behaviours, consciousness and even what it means to be human. Close.

Scientists map part of a mouse’s brain that’s so complex it looks like a galaxy This image provided by the Allen Institute on April 8, 2025, shows a digital representation of neurons in a section of a ...

Making the map. A whole fly brain is less than 1 millimeter wide. The researchers started with one female brain cut into ...

It contains more than 523 million synapses, miles of axons and more than 200,000 cells, and what makes this wiring diagram and brain map unique, is that it also includes functional properties of ...

A similar map has been created for the larva of the same species, but that brain is much smaller, with only around 3,000 neurons. The brain of an adult also has to handle far more information and ...
