Sorry for the late reply been elsewhere.
Now the kind of hibernation you are referring to is actually the most likely to be created if we ever do, a slowing down rather than a true stasis
but it has a number of potential problem's.
Think how your body deal's with radioactive damage which we endure all the time, the DNA repairs itself BUT if you slow that repair process down even
with the best shielding you will actually be in real term's increasing the amount of background radiation damage that the cell nucleus and it's
cytoblasts such as Mitochondria (which has it's own DNA) would then be subject to in real term's a severe increase in relative back ground radiation
and the damage that can then cause to the cell.
In natural hibernating species cell's are simply slowed but no where near as much as we would need for long duration space flight.
So what I was proposing was a technology we have not yet developed a quantum stasis technology OR a freezing technology which would actually stop ALL
cell function and so that would indeed include brain waves, we would also need to perfect a method of shielding the frozen person and there cell's
from radiation exposure OVER TIME, so effectively completely isolate them in some kind of field that was impervious to almost all background radiation
which we must also remember is far greater in space than it is on our planet with our planets natural magnetosphere.
Now I toyed with some idea's but I am neither a physician nor a physicist so this would need to be born in mind.
It would require some form of nano particles to be embedded throughout the body, these particles would react to a certain frequency and dissipate
that through there locality within the body, this would then prevent the formation of ICE crystal's (when you freeze cell's it is not so much the cold
as the formation of ICE crystal's that causes the most damage, as crystal's form they grown and pierce cell membranes and disrupt and tear apart the
internal structure of the cell) this would then allow the cell to be cooled to BELOW freezing point without actually freezing but would actually not
be entering a true state of stasis so this is in fact much more like your idea and there would be at least some cellular activity if very slow so long
as it remained above the threshold necessary to allow the cell's chemical and electrical process to continue which it should as there are arctic fish
that live in temperatures well below freezing but that use natural anti freezing chemical's in there biology which we lack.
This type of SLOWED metabolism state would be a medical breakthrough as well as a potential use for longer duration space flight, still not suitable
for interstellar unless it could be REALLY slowed or we find some method to mix it with a localized time dilation affect of some kind (that would then
amplify it's usefulness exponentially) if we are ever able to create one.
Imagine a patient with terminal cancer and you can not do anything for them BUT what if you could slow there entire body down, regrow there organ's
from healthy cell's, excise the cancer entirely from there body and replace those part's so affected with replacement's grown from there own cell's
then bring them back out of this extremely deep, cold hibernation, even do so locally to the operation site to ensure healing and integration before
then slowly raising there temperature, increasing there metabolism and bringing them out while monitoring for shock and side affects.
But the difference is that true stasis - in the absence of a time dilation field which is then not stasis but time dilation or chronological stasis
which is a different state to true stasis - is a complete PAUSE of all chemical, biological and electrical functions in a subject, this is currently
not possible with our level of science but of course never say never, in that state there would be no brain activity, no dream's.
But in a semi stasis hibernation state indeed you could perhaps with the correct technology TRAIN those in deep sleep by implanting information into
there mind's which would still be there but very much slowed down along with there brain cell's.
Would they learn it though or just wake up with a new store of knowledge and then have to integrate it over an following period of time?.
Here is another weird thought.
Let's take a guy from a really alien world, he has a different approach, his body is absorbed by his ship by first being blended to it by
nanotechnology (perhaps he simply walks into a wall or sit's on what look's like his races equivalent of a chair) then merged so his mind become's the
mind of the ship, the ship's engines are his limb's, it's circuit's his circulation and it's sensor's his senses, when he reaches his destination his
body is recreated from the ship as the nanotechnology reconstructs his body molecule by molecule (or perhaps the ship simply morph's back into him and
is actually very small - just a device he carries on his belt so this would be a nano technology morphing technology of some kind) and he is then
merged back with his body (or his body is de-morphed back into it's alien or humanoid form), the enhances senses of the ship replaced with a sense of
touch, sight and hearing, for him wearing the ship is like us putting on a coat or if morphing like combing his hair.
