[I thought this video would've already been posted, but it seems not to have been (or I couldn't find it). Also, feel free to move to a more appropriate section. I should also warn the squeamish it depicts so very messed up experiments on dogs.]
I recently came across this video again, and did a little research into its origins, as it seems many consider it a fake. (I'm still not 100% sold, but leaning towards 'legit').
It seems to have come from this 1940 film (
Experiments in the Revival of Organisms)
http://www.imdb.com/title/tt0496948/
https://en.wikipedia.org/wiki/Experiments_in_the_Revival_of_Organisms
It is (seemingly) introduced by prominent biologist (and a bit of a polymath) JBS Haldane, and depicts the (in)famous experiments of russian surgeon S.S. Bryukhonenko; basically transplanting (or 'grafting') the head/upper body of one dog onto the body of another (resulting in a truly freaky cerberus-looking creature), and artificially keeping a severed dog's head alive and conscious.
From what I can tell, these experiments are largely accepted as real and 'successful' (though short-lived, due to tissue rejection and other problems). But I wonder if this video is an straightforward filming of the experiments, or if some parts might be a 're-enactment' (for educational/illustrative purposes). The 'head on the table' scenes, in particular, look to me like they might have been faked, with a dog sticking its head through a hole in the table; we never see the severed side or apparatus, and (imho) the head's movements seem very dramatic for having no leverage or points of attachment.
I've seen online opinions from '100% real', to '1940 re-enactment' to 'modern fake', and various combinations thereof. What do other people think? Anyone know of any credible 'expert' opinion, one way or the other?
