Ecosystem for Brain Modeling.

Brain Simulation Ecosystem (BrainX)

Overview

The BrainX ecosystem provides comprehensive framework for brain simulation and modeling. It provides tools and libraries for researchers to model, simulate, train, and analyze neural systems at different scales.

Core components in this ecosystem includes:

• BrainUnit: Comprehensive physical units and unit-aware mathematical system for brain dynamics.

• BrainCell: Intuitive, parallel, and efficient simulation for biologically detailed brain cell modeling.

• BrainMass: Whole-brain modeling with differentiable neural mass models.

• BrainState: State-based IR compilation for efficient simulation of brain models on CPUs, GPUs, and TPUs.

• BrainTaichi: The first-generation framework for customizing event-driven operators based on Taichi Lang syntax.

• BrainEvent: Enabling event-driven computations in brain dynamics.

• BrainScale: Enabling scalable online learning for brain dynamics: $O(N)$ complexity for SNNs, and $O(N^2)$ for RNN computations.

• BrainTools: Commonly used tools for brain dynamics programming, for example checkpointing.

• More components may be added in the future.

Installation

The ecosystem can be installed with the following command:

pip install BrainX -U

This command installs the core package and pins specific versions of the component projects known to work together, ensuring compatibility based on integration tests.

On CPU platforms, the following command can be used to install the ecosystem with all components:

pip install BrainX[cpu] -U

On GPU platforms, the following command can be used to install the ecosystem with all components:

pip install BrainX[cuda12] -U

On TPU platforms, the following command can be used to install the ecosystem with all components:

pip install BrainX[tpu] -U

For development, you might want to clone the repository and install it in editable mode:

git clone https://github.com/chaobrain/brain-modeling-ecosystem.git
cd brain-modeling-ecosystem
pip install -e .
