(#3 on this picture). Also called mesophryon...or maybe the mesophryon only refers to the central point of the glabella?
Apparently there is a "glabellar reflex" - blinking the first few times one is tapped on the glabella - that is apparent in newborns but normally disappears by adulthood.
milpa \'mil-pə\ noun.
1. a) a small field in Central America that is cleared from the jungle, cropped for a few seasons, and abandoned for a fresh clearing.
b) a maize field in Mexico or Central America.
2. the maize plant
I prepare a home for the latest distraction,
A free place in my mind,
The glabellar clearing on my brow
Smoothed of worry to display my new peace.
Nothing else is allowed to grow here:
While I focus, nothing can find me here.
I hide order in a jungle of thoughts,
Like a milpa, tended for a few seasons,
And then the world
And all its troubles
