In a groundbreaking advancement, scientists at the University of Massachusetts Amherst have developed the first artificial neuron that mimics the electrochemical signaling of biological neurons, paving the way for revolutionary brain-computer interfaces and bio-inspired computing.
Published in Nature Communications on September 29, 2025 (DOI: 10.1038/s41467-025-63640-7), this study introduces a device that could transform neuroscience, artificial intelligence, and medical technology.
A Neuron That Communicates Like the Brain
The artificial neuron, developed by graduate student Shuai Fu and associate professor Jun Yao, uses protein nanowires derived from the bacterium Geobacter sulfurreducens. Unlike previous prototypes, this device operates at an ultra-low voltage of 0.1 volts, closely matching the energy efficiency of natural neurons. This allows it to “speak” the brain’s language by transmitting electrochemical signals that living cells can recognize.
This innovation marks a significant leap forward in creating devices that can seamlessly integrate with the human nervous system.
Potential applications include advanced prosthetics, neurorehabilitation tools, and even next-generation AI systems that mimic human brain functions.

Why This Matters
Traditional brain-computer interfaces often struggle with compatibility, as they rely on electrical signals that differ from the brain’s natural electrochemical processes.
The new artificial neuron bridges this gap, enabling direct communication with biological neurons. This could lead to more effective treatments for neurological disorders, such as Parkinson’s disease or epilepsy, and enhance technologies like brain-controlled prosthetics.
The device’s energy efficiency also makes it a promising candidate for sustainable, bio-inspired computing systems, potentially reducing the environmental impact of AI technologies.
The Science Behind the Breakthrough
The artificial neuron leverages protein nanowires, which are biocompatible and highly conductive. These nanowires, produced by Geobacter sulfurreducens, allow the device to replicate the ion-based signaling of biological neurons.
According to the study, this is the first time an artificial neuron has achieved such a close mimicry of natural neural communication.
Funded by the U.S. National Science Foundation and the National Institutes of Health, the research underwent rigorous peer review, ensuring its credibility. The team’s findings highlight the potential for scaling this technology into larger neural networks, which could further advance brain-machine interfaces.
