Well this certainly explains a lot.
Not that we didn't already
know that teenagers are often moody, and at times for no apparent
reason, and that it's been explained away for years as having to do
with hormones. But here's a closer look. At least, it
explains a lot for teenage mice. Apparently, though, a hormone
called THP (also called allopregnanolone) that normally has a calming
effect on adults and young children, has the opposite effect on
teenagers. Uh, teenage mice, that is. The THP is released
in the body several minutes after a stressful event, and normally has a
tranquilizing effect (I think I need more of this), but in adolecsence,
there are more receptors present that accept the hormone in brain
cells, and as a result there is an anxious rather than calming effect
when the THP moves into place in the brain.
In
other words, what is calming for adults and younger children drives
teenagers nuts. Hmm. I think I see that. Not that
this information changes anything, but it does help to understand what
is going on.
