Not sure it would be possible but got me thinking. The brain consists of around 100 billion neurons with a charge of around 0.07 volts at rest. That is a theoretical 7 billion volts. I am not a doctor or electrician but that would have to go somewhere, presumably earth. No idea of the consequences somewhere between none and spontaneous combustion would be my guess!!
This is the best answer and why I was thinking it wouldn’t be possible but couldn’t come up with a good explanation.
Also Cunninghams law in action… post a dumb answer and someone will give the right answer. Thanks.
