Swedish scientists create an artificial neuron that mimicks an organic one
Could remotely stimulate neurons based on specific chemical signals received from different parts of the body, or doctors could artificially bridge damaged nerve cells and restore neural functions

Chemical-to-electrical-to-chemical signal transmission. A conventional neuron (upper panel) senses chemical signals (orange circles), which trigger an electrical pulse of membrane depolarization (action potential) along the axon, causing chemical release at the axon terminals (blue circles). This process can be mimicked (lower panel) by a chemical biosensor (for glutamate or acetylcholine) connected to an axon-mimicking organic electronic ion pump that transmits electrons/ions and generates chemicals — forming an organic electronic biomimetic neuron.

Scientists at Sweden’s Karolinska Institutet and Linköping University have built what they claim is a “fully functional neuron” that mimicks the functions of a human nerve cell.
