Supercomputer Creates Detailed Virtual Mouse Brain
Scientists have made a super-detailed computer model of a mouse brain.
This model has 9 million tiny brain cells called neurons and 26 billion connections between them.
It's like a tiny, super-smart computer brain!
The real mouse brain has about 70 million neurons, but this model helps scientists learn how brains work and how diseases like Alzheimer's happen.
They can do experiments on this computer brain that they can't do on real brains.
This is a big step forward in understanding brains better!
Scientists created a detailed virtual model of a mouse brain with 9 million neurons and 26 billion synapses.
The model simulates the entire mouse cortex, the part of the brain responsible for processing information.
The virtual brain is powered by a supercomputer capable of performing quadrillions of calculations per second.
This model allows researchers to conduct controlled experiments that are impossible to perform on living brains.
The findings were presented at the SC25 supercomputing conference and published online.
