Scientists from the Stanford University's medical faculty developed a model for artificial intelligence that imitates the visual cortex of the mouse brain. In the study published in the natural magazine, these “digital twin” mice were trained with neural activities while watching the film clips.
The model can correctly predict how neurons react to new visual warnings.
Faster research with digital twins
Digital Twin is a virtual copy of the real mouse brain. Prof. “You can experiment with a real model, you can test the best in real brain, said Andreas, Andreas Topias. This can accelerate brain research; years of experiments can be completed within hours.
The model was trained by viewing action films like Mad Max. The ability of mice with low resolution is suitable for recognizing movable scenes. The model with 900 -minün brain activity data can be adapted for any mouse.
The next goal of human brain
This “basic model” can be generalized not only on educational data, but also on new warnings. It can estimate the anatomical properties and connections of neurons. The estimates were confirmed by electron microscope images.
Digital Twin has also unveiled the connecting preferences of neurons. Neurons prefer to connect to neurons that react to the same visual warning.
The researchers want to apply the model to other brain regions and primates. “Some parts of the human brain may have digital twins possible, says Tol Tolias.
