[DiBi]

hi julie, thank you for posting this paper, i found it very very interesting.
unluckily it is still an "intuition", but looks like it has some funding, in my opinion.
the matter is that the brain operation is still widely unknown, and the interactions occourring inside it as well, and i'm afraid that researchers have not enough money available to explore this specific area :-(

on my side, in this short period i'm experimenting with pm, i had reactions similar to sfem and pansy.

if i look at my past i'm lead to think that also other things influenced me, for example when i was still prone to stress, when under pressure my fem side was rising (i say "when i was" because since several years i acquired a quite complete control over stress), so i may think that, at least for me, even adrenaline plays a role.
another thing i noticed: during summertime, when my main activity is tanning :-) , i have less fem inclination, so i think also processes and hormones' production activated by sunlight (like melatonine, that is a precursor of melanine) may have a role as well.

to complicate things, we must consider that all of them (hormones, enzimes, endorphines, etc.) plays with and against each other, on a bunch of neurons deep in the most primitive area of our brain, so identifying things is a very complex issue also for brain research...
