“It’s interesting,” she said. I felt small hands on me, and she heaved me over so I was staring at the ceiling, and at her. Clouds of what looked like steam were rising around her. From the test tubes?
Yeah, looks like Taylor’s going first.
It was having the same effect on my bugs that the aerosol had. She’d erected some kind of gaseous barrier.
Ahh.
“See, there’s this part of the brain that people who study parahumans call the Corona Pollentia, not to be confused with the Corona Radiata.
Pollentia… just looking at the word without looking it up, it sounds like it might have something to do with growth or reproduction, possibly in a metaphorical sense.
It’s a part of the brain that’s different in parahumans, and it’s the part that’s used to manage powers, when the powers can be managed.
Nice. We’re going there, explaining some of the biology behind this stuff.
More specifically, there’s this part of the Corona they call the Gemma, that controls the active use of the power, the same way there are parts of the brain that allow us to coordinate and move our hands.”
So does that mean there’s a part for the passive, subconscious use of the power? Maybe something’s wired up backwards for Imp.
She ran her fingers over my exposed scalp, massaging it, as if she were feeling the shape of my head. “The size, shape and location of the Corona and the Gemma changes from parahuman to parahuman, but it tends to sit between the frontal and the parietal lobe. Beneath the ‘crown’ of the head, if you will.

Alright, so fairly centrally.
They can’t really lobotomize the Corona in criminals. Some of that’s because the location and shape of the Corona depends on the powers and how they work, and trial and error doesn’t work with the scary bad guys who can melt flesh or breathe lasers.”
Ah, yeah, that might be a problem.
And then there’s potential side effects.
Like, what if the corona only keeps their control of the power, not the power itself, making the power go haywire after the removal? Or what if removing it damages other parts of the brain?
