if u rllllllly have to then yes
but generally it is haram because when you die you still can feel and hear etc... plus other abilities. so if some1 cuts u open u feel that
and wen ur dead it feels 100xs more painful. it is said that if a fly is on a dead person it feels like a ton.
Uhh.. I never heard that though.. All I know is once a person is dead, the spirit is disconnected from his body..
There's a story about the body is broken (burnt, etc) when the grave is dug because he's being punished in Kubur, but I've never heard about the opposite, the body is affecting the spirit.
But I can't really say I'm right 100%. Spiritual realm is outside our reach after all..
IMO, if it's for study (human anatomy or autopsy), it's alright.
