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:
- Living
neurons grown in laboratory conditions
- Electrode
arrays connecting neurons to computers
- Digital
software sending signals to neurons
- 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.

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:
- energy
efficiency,
- real-time
learning,
- pattern recognition,
- and
adaptive intelligence.
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.
Why Biological Computers Matter

scalability challenges.
Biological computing may eventually help solve some of these
issues.
Potential advantages include:
