The heart creates it's own electrical pulses.

The heart will still beat when disconnected from the body.

You are speaking confidently about something you don't thoroughly understand

As long as it was fed oxygen... Yes. I think that's where you're being confused... The brain does play a role in the heart pumping... by keeping the other organs supplying the heart with what it needs.

It's why people that are "brain dead" can be kept "alive" for a while, with a machine that breathes for them. The brains not sending the signals to the lungs to get oxygen in the blood stream to supply the heart with the energy it needs to beat.

You don't? Why?

I'm sure you can go on liveleak to find some decapitation video, but from seeing a cow get slaughtered by decapitation myself, the heart definitely keeps pumping blood for a good while

You don't understand the concept of a sodium potassium pump in cellular biology?

What does that have to do with the heart requiring brain activity to function?
