While this or that study rediscovers it, all of this
stuff has been long-known.
I should look-it-up before 'spouting-off', but I 'think',
if you search on "Cluver-Bucy Syndrome", you'll see
what I mean.
Anyway, it was all established before I began
working in Neuroscience in 1971.
There were a lot of correlated studies done in
Monkey [hypersexuality post amygdalotmy,
which means that, with respect to sexuality,
the amygdala is a "supersystem configuration"
mechanism [AoK, Ap5], =not= the 'whole
story'.
