The Harvard-Google DeepMind collaboration has developed an artificial neural network capable of guiding a virtual rat’s movements within an ultra-realistic physics simulation. This achievement closely mirrors the intricate coordination of complex behaviors observed in biological brains.
This groundbreaking virtual rat brain model provides unprecedented insights into the neural mechanisms underlying motor control, cognition, and neurological disorders. By combining advanced machine learning techniques with high-fidelity simulations, this breakthrough paves the way for transformative progress in neuroscience, robotics, and our understanding of biological intelligence.
The virtual rat is driven by an artificial neural network that closely mimics the neural activity of real rats, providing a unique opportunity for researchers to compare the two. Despite animals having “exquisite” control over their bodies, allowing them to perform a wide range of behaviors, the precise mechanisms by which the brain achieves this control remain elusive.
To delve deeper into understanding brain function, researchers trained the virtual rodent to replicate the whole-body movements of freely moving rats within a physics simulator. In this setup, an artificial neural network controlled a biomechanically realistic model of the rat.
The findings revealed that the virtual rodent’s neural networks, which implement inverse dynamics models, were more accurate predictors of neural activity than measurable features of movement, such as joint positions or velocities, or alternative control models. This was achieved using deep reinforcement learning to train the virtual agent to imitate the behavior of freely moving rats, as detailed in their paper published in Nature.
The study demonstrated how physical simulations of biomechanically realistic virtual animals can help interpret neural activity structures across different behaviors and relate them to theoretical principles of motor control.
According to their research approach can be broadly applied in neuroscience to facilitate the study of neuromotor control aspects that are challenging to deduce experimentally. It could also play a crucial role in modeling the neural control of increasingly complex animal behaviors.
