Harvard University Researchers and Google DeepMind Scientists Collaborate to Create Artificial Brain for Virtual Rat

In a groundbreaking partnership, Harvard University researchers have teamed up with Google DeepMind scientists to develop an artificial brain for a virtual rat. This innovative breakthrough, published in Nature, signifies a significant advancement in studying how brains control complex movements through advanced AI simulation techniques.

Constructing the Virtual Rat Brain

The research team utilized high-resolution data from real rats to build the virtual rat’s brain. Collaborating closely with DeepMind, the Harvard researchers created a biomechanically realistic digital model of a rat. Graduate student Diego Aldarondo worked with DeepMind researchers to train an artificial neural network (ANN) – the virtual brain – using deep reinforcement learning, a powerful machine learning technique.

The neural network was trained to use inverse dynamics models, similar to those used by human brains for guiding movement. This enabled the virtual rat’s brain to calculate trajectories and translate them into motor commands, mimicking real-life behaviors such as reaching for objects. Through reference trajectories derived from real rat data, the neural network learned to generate forces for a wide range of behaviors.

Potential Applications and Implications

The virtual rat with its artificial brain offers a new approach for exploring the neural circuits responsible for complex behaviors. This research could also lead to the development of more advanced robotic control systems, as well as pave the way for “virtual neuroscience,” where AI-simulated animals are used as models for studying the brain in various states, including diseases.

Advancing Towards More Virtual Rat Autonomy

Building on this achievement, the researchers aim to grant the virtual rat more autonomy to tackle tasks akin to those faced by real rats. By doing so, they can explore the learning algorithms that underlie the acquisition of new skills and behaviors, shedding light on how real brains learn and adapt.

Ultimately, this collaborative effort between neuroscientists and AI researchers aims to enhance our understanding of how real brains generate complex behaviors. By refining and expanding upon this innovative approach, they hope to unravel the mysteries of the brain and create more intelligent, adaptable systems.
