<div>IIUC, RMT's position regarding brainstem death is linked to autorespiratory ability, not cardiac death. I don't think the heart beat requires a functioning brainstem.</div>

<div>Re heart transplants and techiyas hameisim - the Tzitz Eliezer has a lengthy discussion about this, or very much related to this, somewhere in his huge 10:26 series of Teshuvos. IIRC there is no identity shift when the recipient gets the new heart. Otherwise, this would mean that he is his artificial heart, which is ludicrous.</div>

<div>R' Slifkin's article was irrelevant to the issues, and had some demonstrably incorrect assertions. </div>

<div>An interesting Yerushalmi in 3rd chapter of Niddah - the way you define whether a person is a human or animal (relevant to the aforementioned article) is not by his daas, it is by his facial features (those he was born with, I presume). Even if someone with a bovine face is up there reading the Torah, you can tell him "come, let us slaugter you", and even if one with a human face is plowing in the field, we tell him to give his sister in law yibum or chalitzah should the need arise. [This Yerushalmi is brought about in respect to anencephalic babies - they may not be born with a tzurah (facial characteristics) of an adam! RSZA held that they most probably may be killed in utero, but not once they were born.] </div>
