Editing Corona Pollentia (section)

===Size, Location, and Integration===
The size, shape, and location of the Corona and the Gemma changes from parahuman to parahuman. Usually, it starts as 1-1.6 inch-sized body settled between the frontal and the parietal lobes.

During the [[trigger]] event, Corona gets a spurt of development. It is a partial reason for people blacking out. Corona expands slightly, veins swell.<ref name="I26 e1">But the entity can still see fallout effects.  There are parallels in memory storage.

It finds a manner in which it can operate, then alters itself, solidifying into a particular state.  The remainder of the functions are discarded, the ones in the shard itself are rendered inert to conserve power, while the ones in the host fall away, are consumed by the shard.

Young triggers have more pronounced Corona Pollentia with a noticeable effect called 'dimpling,' as if it is pressed down into the brain, and, sometimes, expanded webbing, enveloping the brain.<ref name="T7.6"/>

It is possible to get an impression of power expression from how Corona Pollentia is integrated with the brain. E.g. strong [[wikipedia:frontal lobe|frontal lobe]] connection indicates [[Thinker]]-type perception powers, and [[Master]]s would get a stronger emphasis on the [[wikipedia:cerebellum|cerebellum]].<ref name="T7.6">“Corona Pollentia,” I said.  “She has powers.”<br><br>[...]<br><br>“They take different forms.  There aren’t hard and fast rules.  But I’ve heard that if you trigger young, it takes more of a hold, with more… it’s called dimpling.  Like a hand is actually pressing it down into the brain.  That right there looks like dimpling.”<br><br>[...]<br><br>“You get more cloudiness in some kinds of scans where it expands out into the webbing around the brain, but we’re not getting that.  It’s been way too long since I studied this,” I said.  “The corona starts as a single marker, like a quarter-sized knot in wood, or a ball the size of a golf ball, pushed between the two lobes.  Then when we trigger, it surges into life.  It’s part of the reason we black out.  It expands slightly, veins swell.  But most of the time an unactivated corona is hard to tell apart from an activated one, and a surprising number of people have unactivated ones.  Sometimes you look at them and the larger veins or structures suggest what the power is linked to.”<br><br>“What does this tell us?” Chris asked.<br><br>“She triggered young.  It’s deeper set.  People who had a corona for a long time don’t get dimpling, I’m pretty sure.  Looking at the veins, where it seems to have reached out…<br>[...]<br>...Cerebellum is senses, seeing, hearing, coordination of movement.”<br><br>“That makes me think of Mama Mathers,” Sveta said.<br><br>“If thinkers had an emphasis, I think it leans more toward frontal lobe.  This could be a perception power, I guess.” - [https://www.parahumans.net/2018/06/09 Excerpt] from [[Torch 7.6]]</ref>
