Electronic conversations between neurons could soon be recorded precisely

Electrodes are used to pick up electrical signals. Neurons however are tiny units of the nervous system and it is difficult to create an electrode small enough to record all the workings of a neurons. Researchers from Harvard University have overcome this obstacle by creating an electronic chip that could be implanted within these networks and could thus perform highly sensitive intracellular recordings of the neurons individually. This could be a boon for neuronal research believes the team as it could help provide an in-depth knowledge of the neuronal connections and synaptic workings. The team wrote, "Current electrophysiological or optical techniques cannot reliably perform simultaneous intracellular recordings from more than a few tens of neurons."
