>>12086457Basically electrical impulse near the sphagetthi that contain ionpumps and voltage gated stuff would cause it to fire and end up with stuff accepted by dendride as information, same way you can measure electrical pressure near axon to get information without actually getting in the way of it.
That's how neuralink is supposed to work.
However modulation like neurotransmitter provide is almost unreal to create artificially, but you could create pressure in synapse that releases neurotransmitter, due to information can get there only by voltage, or just inject neurotransmitters near synaptic space to commit infomation, but that would lead to possible reuptake, which you may not desire.
You can create independent neural loops in brain having access to axon precise implants.
