I did not address you, but so far I agree with you! :-)

It is fun and not necessarily (entirely) false. In fact, or at least to me,
the 'filtering/focusing/fixing' functions performed by certain
neuromodulators correspond to contents qualities/levels and intensities of
Consciousness in a *roughly* (or only very approximate - even very vague -
*but fun to recognize*) neuromodulator-specific way.

But you (people) are of course free to disagree. :-)

I, in my post, tried to at least touch on the fact that *they do*; and that
they do by pre and post synaptic "gating" of amygdala originating axons WHEN
these signal alerts about some "selectiv Hibernation imploring type" adverse
aspect of the individuals current, OR some such PAST (no longer
environmentally caused) life-situation.

Adversity detecting amygdala neurons certainly play a significant and
central role but they are not the only actors in need of occasional (or
chronic - whence a SHITS have been stored as CURSES) moderation by
self-regulatory inhibitory feedback.
