What is the practical reason to favor electrical implants over electromagnetic ones? One would conclude that using electromagnetic induction would be a no-brainer when it is very clear the body works against electrical probes (by fighting the implants). Could someone more knowledgeable than myself clarify this.
- jupp0r 3y agoI don't know the answer to your question, but I appreciate the "no-brainer" pun there.
- 0xbadc0de5 3y agoIt's very difficult (ie: impossible) to target individual nerve fibres with induction. Direct stimulation is the only way to achieve the required resolution.
- hprotagonist 3y agosee also, MEG
- etrautmann 3y agoThe amount of current required for magnetic stimulation is much higher and not compatible with implantable devices. TMS requires large coils and currents relative to electrical stimulation.
- barelyauser 3y agoIsn't TMS coil current high to compensate the distance? The closer to the nerve ending should reduce the necessary current.
- Jeff_Brown 3y agoBut if those nerve endings are anywhere but at the surface of the body, they'll still require an implant.
- __loam 3y agoBio-compatibility issues are not intractable. We know about many biomaterials that the body doesn't have a strong adverse reaction to. I'm sure people are developing materials that are both conductive and bio-compatible.
