Biohacking is not feasible at this time—at least in my opinion:
* TMS machine is a powerful precise device that is expensive and unlikely to be safe from doing-it-yourself
* Every brain is different, so, you’ll need to get an MRI if not an fMRI to understand the structure to target
* Once you have a target, you’ll need to align the device with your skull
* It’s not clear how you’d measure or control the regime on the brain, even if you made it to here
The last thing I’ll say is that you should look for the complaints made against TMS device manufacturers. I’m optimistic that this approach will work for some people; I know many people who could benefit from this technology but I’m not comfortable with recommending it to a family member when I know there’s a risk of permanent brain damage, tinnitus, etc.
