The distinctive troughs and crests of the human brain are not present in most animals; highly folded brains are seen only in a handful of species, including some primates, dolphins, elephants and pigs. In humans, folding begins in fetal brains around the 20th week of gestation and is completed only when the child is about a year and a half.
Why the brain is folded can be rationalized easily from an evolutionary perspective; folded brains likely evolved to fit a large cortex into a small volume with the benefit of reducing neuronal wiring length and improving cognitive function.
Less understood is how the brain folds. Several hypotheses have been proposed but none have been directly used to make testable predictions. Now, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences collaborating with scientists in Finland and France have shown that while many molecular processes are important in determining cellular events, what ultimately causes the brain to fold is a simple mechanical instability associated with buckling.
Neuroimaging studies suggest that frontolimbic regions of the brain,
structures that regulate emotions, play an important role in the biology
of aggressive behavior.
A new article published in the inaugural issue of the journal Biological Psychiatry: Cognitive Neuroscience and Neuroimaging
reports that individuals with intermittent explosive disorder (IED)
have significantly lower gray matter volume in these frontolimbic brain
structures. In other words, these people have smaller “emotional
“Intermittent explosive disorder is defined in DSM-5 as
recurrent, problematic, impulsive aggression,” explained Dr. Emil
Coccaro, the article’s lead author. “While more common than bipolar
disorder and schizophrenia combined, many in the scientific and lay
communities believe that impulsive aggression is simply ‘bad behavior’
that requires an 'attitude adjustment.’ However, our data confirm that
IED, as defined by DSM-5, is a brain disorder and not simply a disorder
of 'personality.’” Dr. Coccaro is the E.C. Manning Professor and Chair
of Psychiatry and Behavioral Neuroscience at the University of Chicago.
Coccaro and his colleagues also report a significant inverse
correlation between measures of aggression and frontolimbic gray matter
The investigators collected high-resolution magnetic
resonance imaging (MRI) scans in 168 subjects, including 57 subjects
with IED, 53 healthy control subjects, and 58 psychiatric control
subjects. The team found a direct correlation between history of actual
aggressive behavior and the magnitude of reduction in gray matter
volume, linking both in a dimensional relationship.
subjects, reduced volume in frontolimbic brain structures was associated
with increased aggressiveness,” commented Dr. Cameron Carter, Professor
of Psychiatry and Behavioral Sciences at University of California,
Davis and Editor of Biological Psychiatry: Cognitive Neuroscience and Neuroimaging.
“These important findings suggest that disrupted development of the
brain’s emotion-regulating circuitry may underlie an individual’s
propensity for rage and aggression.”
Can we talk about Weiss’ character development for a second here?
The girl was worried about Velvet getting hurt; when two volumes ago I can guarantee you she wouldn’t be yelling at Coco for letting Velvet, a Faunus, walk straight into harm’s way.
She straight up sprinted forward to protect Velvet, not sure if her summoning was even going to work. She was going to take the hit for Velvet. She didn’t even try to cast a sigil or use the Dust in Myrtenaster to strengthen herself. She threw herself in front of Velvet.
Weiss Schnee; heiress to the SDC, known for their mistreatment of Faunus. Someone who was more than willing to write off all Faunus as “miscreants” and “criminals”, who compared Faunus to trashcans and lampposts. Who cared more about how she felt than how she treated others.
Weiss has thrown herself into a lava plume for her teammate. She’s taken hits for her teammates. She was willing to lay down her life for her friend without a second thought.
Weiss Schnee has grown so fucking much and I am so proud of her character.
So I spent this morning doing the final pass on an upcoming volume, and here are a few of the highlights. I made myself sad. Because I’m a terrible person.
If you want more of my terribleness, I guess you could follow me on Twitter~ 😅 (twitter.com/MistreKirin)
