Study examines why the memory of fear is seared into our brains
Science Daily ^

...

In a nutshell, the researchers found that the stress neurotransmitter norepinephrine, also known as noradrenaline, facilitates fear processing in the brain by stimulating a certain population of inhibitory neurons in the amygdala to generate a repetitive bursting pattern of electrical discharges. This bursting pattern of electrical activity changes the frequency of brain wave oscillation in the amygdala from a resting state to an aroused state that promotes the formation of fear memories.

Published recently in Nature Communications, the research was led by Tulane cell and molecular biology professor Jeffrey Tasker, the Catherine and Hunter Pierson Chair in Neuroscience, and his PhD student Xin Fu.

Tasker used the example of an armed robbery. "If you are held up at gunpoint, your brain secretes a bunch of the stress neurotransmitter norepinephrine, akin to an adrenaline rush," he said.

"This changes the electrical discharge pattern in specific circuits in your emotional brain, centered in the amygdala, which in turn transitions the brain to a state of heightened arousal that facilitates memory formation, fear memory, since it's scary. This is the same process, we think, that goes awry in PTSD and makes it so you cannot forget traumatic experiences."

Politics has been injected into science (through the grant system, of course).

Politics kills whatever it touches.

The only thing you have to fear is a tyrannical authoritarian government disguised as a democracy.
And or psychopaths.

I’m currently studying trauma and the effects it has on people in varying degrees of traumatic experiences. This is a revealing study and one that matters in the treatment of PTSD. The article does a disservice to the study... it’s like someone wrote a note about doing an article and published the note... not the article.

The old song “School Days” was ahead of this research by over a century. “Reading and Writing and ‘rithmatic, are taught to the turn of the hickory stick”. Fear focuses the mind. D’oh!

Natural selection.

Those who remember the stupid things they did that almost got them killed don’t do them again.
