How About Them Amygdalas?

Have you ever wanted to just... disconnect from the flight response that the amygdala provokes in your body? Have you considered how much more you could get done without wanting to duck and cover under the nearest solid thing you can find? I know I've wanted to.

What's an Amygdala?

The dictionary in Edovo (to do: ask Edovo for pronunciation keys for words) states:

amygdala

NOUNS - amygdala, amygdaloid nucleus, corpus amygdaloideum

Definition
an almond-shaped neural structure in the anterior part of the temporal lobe of the cerebrum
intimately connected with the hypothalamus and the hippocampus and the cingulate gyrus
as part of the limbic system it plays an important role in motivation and emotional behavior

For short periods of time, I've been able to disconnect from the flight response in the past, aided by prescription clonazepam. It tamps down the "Aaaaa? Aaaaa!!" in my head for many things.
Sitting in the dentist's chair and he's about to inject me with lidocaine to numb me for work goes from "I can't flee, so a haymaker for thee! (sorry, doc! ^^;)" to "Huh. He injected me. Okay." Dental work became easier without scaring nurses: I turn gray and just about faint under oral needle injections when I can fight down the reflex to punch or push, minus the clonazepam. My blood pressure actually measurably drops because of how strong the response is without damping -- hooray for states of deliquium!
Sitting on the airport runway preparing to take off goes from "Let me off this metal tube NOW. There is a perfectly good GROUND to walk on outside this contraption!" to "Okay, pilot's got a headwind, clearance from tower, ooof, seat glued... and there's the lift. Banking now for the flight line from EUG to DEN." Travel became easier when I positively need to get across country posthaste. ... though I admit a small sense of hindsight humor in spooking the officers who transported me clear across country on two flights to bring me to Florida without meds.
I did try to warn them, at least.

I digress. What if there were a natural neurohack for getting your brain to skip the amygdala's flight response, minus the need for pharmaceutical intervention or the use of substances like marijuana?
I've been giving boxed breathing a try, which in my case does disarm some of the "Aaaaa??" that lives in my head; but I don't think it will fully tamp down the flames of gibbering in abject fear that is ever present in my daily narrative.

But, I think it's actually a good thing that most of us humans have that heat in the center, that screaming voice that tells us in whatever language or symbology we understand that NO! FIRE BURN HOT, FIRE BURN FACE!, the one that encourages us to back down from doing absolutely insane things that do not encourage us to be humans together. If only having a proper fear response were a requirement for becoming an elected official. :')
