A team from the Jülich Research Centre in Germany is working on creating a complete human brain simulation using the JUPITER supercomputer. This system, ranked fourth globally in power, has previously stalled projects like the Human Brain Project.

The team successfully scaled a spiking neural network model to replicate the human cerebral cortex's 20 billion neurons and 100 trillion connections. The model utilizes real anatomical data and aims to uncover brain functions and test drug responses for conditions such as epilepsy. While promising, experts note that essential brain functionalities, including sensory input, are not yet replicable.
