Do you know you can easily kill yourself with a 9-V battery. Insert a needle
in one of your left fingers, and in one of your right fingers. By inserting
a needle, you can make the impedance in the couple of Ohms range. I = V/R,
and with R below 18 Ohms, and V = 9 volts, you get 1/2 Amp through your
heart, which is guaranteed to stop your heart. If you time it well, though, a
few mA will stop your heart too, so you only need the resistance to be below
1 kOhm and some luck with the timing.

I am not sure what current you need to fry your brain, though.
