Background:

Existing neuronal and neural circuit simulation methods have limitations for large-scale tissue modeling.
A comprehensive tissue coordinate system is required for advanced neural simulations.

Purpose of the Study:

To develop a novel, ultrascalable method for simulating neural tissue.
To enable simulations of unprecedented scale, approaching human brain complexity.

Main Methods:

Developed a novel tissue volume decomposition strategy for parallel processing.
Implemented a hybrid branched cable equation solver to handle neurons across distributed blocks.
Demonstrated scalability on a large parallel machine (4000+ nodes, 4 threads/node).

Main Results:

Achieved significant thread, strong, and weak scaling for the neural tissue simulation.
Local computation of synapses due to decomposition minimized performance impact.
Successfully simulated 1 million neurons, 1 billion compartments, and 10 billion synapses.

Conclusions:

The developed Neural Tissue Simulator is ultrascalable and efficient for large-scale neural modeling.
Results provide insights into the computational requirements for simulating a human brain.
The method overcomes previous constraints in simulating complex neural systems.
