Detection and production of dopamine as a response mechanism by artificial neuron


Key points from article :

An artificial neuron that is able to communicate using the neurotransmitter dopamine was developed.

Researchers have developed a brain-machine interface that can communicate based on chemically mediated signals rather than electric signals.

An artificial neuron that could both detect the presence of dopamine and also produce dopamine as a response mechanism was built.

The neuron is made of graphene and a carbon nanotube electrode.

The ability of their artificial neuron to communicate was tested by placing it in a petri dish with some brain cells collected from a rat.

They acknowledge that their setup is quite bulky, which would limit its use as a brain-machine interface.

They published their creation in the journal Nature Electronics.
