braincog

BrainCog is an open source spiking neural network based brain-inspired cognitive intelligence engine for Brain-inspired Artificial Intelligence and brain simulation. More information on braincog can be found on its homepage http://www.brain-cog.network/

The current version of BrainCog contains at least 16 functional algorithms (including but not limited to perception and learning, decision making, knowledge representation and reasoning, motor control, social cognition, etc.) built based on BrainCog infrastructures, and BrainCog also provide brain simulations to drosophila, rodent, monkey, and human brains at multiple scales.

If you use braincog in your research, the following paper can be cited as the source for braincog.

Brain-Inspired AI

braincog currently provides cognitive functions components that can be classified into five categories:

  • Perception and Learning
  • Decision Making
  • Motor Control
  • Knowledge Representation and Reasoning
  • Social Cognition

Brain Simulation

braincog currently include two parts for brain simulation:

  • Brain Cognitive Function Simulation
  • Multi-scale Brain Structure Simulation
