Summary

• What is new: Introduction of BrainPy, a differentiable brain simulator using JAX and XLA, aimed at merging brain simulation with brain-inspired computing.
• Why this is important: Lack of a common programming framework that supports both brain simulation and brain-inspired computing due to traditional simulators’ lack of differentiability and DL frameworks’ failure to capture brain dynamics complexity.
• What the research proposes: BrainPy, a differentiable simulator that bridges the gap by expanding JAX functionalities for brain simulation, offering efficient and scalable simulation tools, and providing a flexible interface for multi-scale brain modeling.
• Results: Demonstrated efficiency and scalability on benchmark tasks, and highlighted the potential of differentiable simulation for biologically plausible spiking models.
