Cortical Labs: Brain Cells Driving Next-Gen AI Chips


Artificial intelligence is evolving at an incredible pace, but modern AI systems face a growing challenge: energy consumption. According to estimates from the International Energy Agency, large AI data centers may consume more electricity than some small countries within the next decade. This growing demand has pushed researchers to explore alternatives beyond traditional silicon chips , and one of the most fascinating developments is biological computing.

At the center of this revolution is Cortical Labs, a company developing systems that combine living brain cells with computer hardware to create a new form of intelligence known as Synthetic Biological Intelligence (SBI).

What once sounded like science fiction is now becoming a real field of research. Biological computers powered by neurons may eventually reshape AI chips, robotics, scientific research, and even the future of computing itself.

In this article, we will explore:

  • what Cortical Labs is,
  • how brain-cell computing works,
  • how biological AI differs from traditional AI,
  • technical architecture behind neuromorphic computing,
  • current use cases,
  • real-world experiments,
  • ethical concerns,
  • and the future of biological intelligence.

What Is Cortical Labs?

Cortical Labs is an Australian biotechnology and AI company focused on developing biological computers using living neurons. Instead of relying entirely on silicon-based processors, the company integrates human brain cells with digital systems to create adaptive computing platforms.

The company became globally recognized after demonstrating systems where lab-grown neurons learned to interact with simulated environments. One of the most famous demonstrations involved neurons learning to play a simplified version of the classic game Pong.

While the experiment appeared simple on the surface, the implications were enormous. It suggested that biological neurons could:

  • process information,
  • adapt dynamically,
  • learn from feedback,
  • and potentially perform certain tasks more efficiently than conventional AI models.

This concept is known as:

Synthetic Biological Intelligence (SBI)

SBI combines biology, neuroscience, AI, and computing into a hybrid intelligence system.

Understanding Biological Computing

Traditional computers process information using silicon transistors. Biological computers, however, use living neurons as computational elements.

In simple terms:

  • traditional AI chips use electrical circuits,
  • biological computers use living neural networks.

Human neurons are incredibly efficient. The human brain performs billions of operations while consuming roughly 20 watts of power — less energy than many household light bulbs.

Modern AI systems, on the other hand, require:

  • massive GPU clusters,
  • expensive cooling systems,
  • and huge amounts of electricity.

This is why researchers are increasingly interested in neuromorphic computing and brain-inspired AI systems.

How Brain Cells Work Inside AI Systems

To understand Cortical Labs’ approach, it helps to simplify the process.

The system generally involves:

  1. Living neurons grown in laboratory conditions
  2. Electrode arrays connecting neurons to computers
  3. Digital software sending signals to neurons
  4. Feedback loops allowing learning behavior

The neurons communicate using electrical impulses, similar to how neurons operate in the human brain.

The system observes:

  • how neurons react,
  • how they reorganize connections,
  • and whether they learn patterns over time.

This creates a form of adaptive biological computation.

What Makes Biological AI Different?

Modern AI models like deep learning systems are powerful but extremely resource-intensive. Biological computing aims to mimic the efficiency of the brain itself.

Here is a comparison between traditional AI chips and biological computing systems.

This comparison explains why neuromorphic computing has become one of the most exciting areas in AI research.

What Is Neuromorphic Computing?

Neuromorphic computing refers to hardware and software systems designed to imitate the structure and behavior of the human brain.

Instead of processing information in rigid linear ways, neuromorphic systems:

  • distribute computation,
  • adapt connections dynamically,
  • and process information simultaneously.

Major technology companies are also researching this field because traditional chip scaling is slowing down.

Neuromorphic AI aims to solve problems such as:

Biological computing takes this concept even further by incorporating real neurons instead of merely simulating them.

The Pong Experiment That Changed Public Attention

One of Cortical Labs’ most widely discussed demonstrations involved neurons learning to play Pong.

The setup worked like this:

  • neurons received electrical signals,
  • the system represented ball movement,
  • successful actions created predictable feedback,
  • unsuccessful actions produced random stimulation.

Over time, the neurons adapted their responses to improve performance.

Why was this important?

Because it demonstrated:

  • adaptive learning behavior,
  • environmental response,
  • and goal-oriented activity.

Even though the game itself was simple, the underlying principle was groundbreaking.

It showed that living neurons connected to machines could:

  • learn,
  • respond,
  • and optimize behavior.

DOOM 3D Game and Brain Cells

Researchers at Cortical Labs gained global attention after demonstrating experiments where living brain cells interacted with digital gaming environments. Following the famous Pong experiment, discussions around applying similar biological intelligence systems to more complex games like Doom sparked interest across the AI community.

The idea behind a Doom-style experiment is not about neurons “playing games for fun,” but about testing adaptive learning, decision-making, and environmental response in biological computing systems. Games like Doom provide dynamic environments with movement, obstacles, reactions, and feedback loops — making them useful for studying intelligent behavior.

Traditional AI models require enormous computational power and extensive training data. Biological neuron systems, however, may learn patterns differently through real-time interaction and adaptive neural responses. Researchers use electrode arrays and stimulation signals to observe how neurons respond to digital stimuli and optimize behavior over time.

These experiments represent an early but fascinating step toward brain-inspired AI and future neuromorphic computing systems.
