New artificial neuron will help restore neuronal functions

Neurological disorders are currently treated using traditional medications and electric stimulations. A group of scientists at Karolinska Institutet in Sweden has recently developed an organic electronic neuron made of conductive organic polymers. This artificial neuron is able to function like a real human neuron: It can sense changes of chemical signals and translate these signals into an electrical impulse that causes the release of a neurotransmitter (e.g., acetylcholine). The effects induced by the neurotransmitter’s release can be further measured on human cells in vitro. This new neuronal model will help to bypass damaged nerve cells and restore neural function, possibly contributing to the treatment of neurological disorders.
