Brain Pacemakers & Dangerous Brain Implants
I need some information on brain pacemakers and rare forms of hospital-administered procedures easily classified as, "biohacks". I have severe epilepsy and I already have an ambulatory EEG permanently hooked up to me modified to act as a monitoring system but firstly they're upgrading it to use electrodes implanted directly in my brain in tandem with Vagus Nerve Stimulation (a brain pacemaker) for medical reasons.
Does anyone here have experience with rare and invasive brain implants rarely implemented on humans? These implants would under no circumstances be accessible to standard body-modders and are state-of-the-art pieces of unfathomably expensive medical hardware so any information would be appreciated. I asked the doctors but the specific implants are 2 months old meaning any possible risks from the nuances of the hardware cannot be predicted until I'm hooked up in a few months.
Also for those curious, brain pacemakers allow one to adjust the pulses sent by the device so I would have, at least in this one medical instance, have complete control over my VNS system. No I don't know if that's dangerous but a team of neurologists thought of it and prescribed it so I'm fairly trusting.
Also no, I have absolutely no implants I got willingly. Everything I have essentially serves as portable life-support so I have a lot of experience with medical implants.
