The scientists immediately discovered a strong neural signal, emanating from dopamine-rich areas of the brain, that seemed to be driving many of the investment decisions.

The encoding of the pressure stimulus in the neural signal was measured by the coherence of the stimulus and response.

This polarization ultimately leads to either the transmittance or inhibition of a neural signal that will be fed to the brain via the optic nerve.

Other research has tried to decode words and sounds directly from neural signals, skipping the middle step of decoding movement.

Others have decoded words people have spoken 'in their head' by matching neural signals to those sent when saying the same words aloud.
