Scientists from Karolinska Institutet in Sweden have constructed the world’s first artificial neurons that could possibly replace some real ones in your brain.
In a new study published in the journal Biosensors and Bioelectronics, the scientists were able to build artificial neurons using molecules or polymers. They connected enzyme-based biosensors to organic electronic ion pumps which enabled the artificial neurons to mimic the function of real neurons. Even over large distances, it was proven that artificial neurons can communicate chemically with organic brain cells.
“We foresee that in the future, by adding the concept of wireless communication, the biosensor could be placed in one part of the body, and trigger the release of neurotransmitters at distant locations,” said Agneta Richter-Dahlfors, lead researcher of the study.
In their experiment, it was shown that the artificial neuron’s sensing component is capable of sensing a change in chemical signals in one dish and then translate it into an electrical signal. The electrical signal is then translated into the release of the neurotransmitter acetylcholine in a second dish. Its effect on living human cells can be monitored in the dish.
Theoretically, artificial neutrons can be integrated in biological systems including the human body. Thus, scientists can possibly replace or bypass damaged nerve cells in patients. Moreover, the device can be used to develop new treatments for neurological disorders such as Parkinson’s disease and spinal cord injuries.
The artificial neurons are as small as the size of a fingertip and have no living parts. The research team hopes to miniaturize the device for implantation into the human brain.
