How the Brain Handles the Unknown (axios.com) 21

Uncertainty can be hard for humans. It drives anxiety, an emotion neuroscientists are trying to understand and psychologists are trying to better treat. From a report: Under the threat of a virus, job insecurity, election uncertainty, and a general pandemic life-in-limbo that is upending school, holidays and more, people are especially anxious. Before the pandemic, anxiety was already climbing in the U.S., especially among young adults, according to a recent study. Add the pandemic and its many unknowns: 35% of adults in the Household Pulse Survey reported symptoms of anxiety disorder in July. (In the first half of 2019, it was roughly 8%.) "We have anxiety for a reason," says Stephanie Gorka, who studies the neurobiology of anxiety and treatments for anxiety-related disorders and phobias at the Ohio State University. Anxiety alerts people to pay attention to their environment and is key to our survival, but if it is chronic or excessive, it can have negative health consequences, she says. But how exactly the brain responds to uncertainty and leads to anxiety is unclear.

      My father was in hospice and my (adult) daughter had volunteered to spend the night with him in case he woke up and was confused.

      She was awoken by a one sided conversation, where my father was talking to somebody, but there was nobody in the room. My father was trying to get them to put some eyedrops in his eyes, and then he commented that he was surprised that (the person he was talking too) had eyes that were all black. My daughter was shaken to the core, but my father had a pleasant conversation and ended it by going back to sleep.

      It may have been an incubus nightmare, it may have been death (he passed a couple days later), but it solidified my admiration for my father's brave nature when faced (or imagining) something that would give any other adult there terrors.

      • When we are dreaming, we are often able to accept things as normal that would terrify us to imagine while we are awake.

        I've been shot, stabbed, burned, drowned, and all manner of other things while dreaming. I just shrugged it off, decided I must be dead now in the dream, then carried on.

  • I can't remember where I read this, probably at a TED talk by a NYU psychology prof. At one time, it was thought that left side is responsible for the analytic processing, while as the right side handles the creative tasks. That seems to have been discarded. What has reappeared in its place is that once side seems to be for dealing with planning and rationality. The other side seems to be for dealing with chaos and uncertainty. This seems to be an evolutionary need for the circumstances where an early

    Nonstop news media hype about the bogeyman is causing Americans to suffer from anxiety disorder. If they cared about Americans at all they would go back to reporting facts and recounts about what happened instead of conspiracy theories and speculation and posturing and hype.

      the pandemic is real. And I think it's safe to say the President giving a violent White Supremist group a wink and a nod during a presidential debate and then calling for poll watchers is cause for alarm. As is the $1.1 billion he owes to God and his accountant only know who. Or that he now as a virus that is known to have neurological side effects....

      At a certain point fear is justified and necessary. I get the boy who cried wolf but at this point said wolf is chewing on our arms.

        Obsessed haters of various types habitually change the subject of conversations to whichever race or nationality or group or individual they hate, even when others are discussing a completely different subject. That's what you have done here.

    These are things that break our rationality to prevent us from becoming completely insane. May sound bad on the surface but think about it.
  • Fear, fear of death. Thats how the brain handles everything. And if left unchecked the ego takes over and its how it ruins our lives and runs the world.

    We've been dealing with highly contagious pathogens for thousands of years. There was a time when they were an unknown; Acts of God, but even when we didn't have a germ theory of disease, we had enough observational data to know how to deal with them, at least crudely. Quarantines long predate direct identification of pathogenic organisms. In some ways, I suspect our ancestors probably dealt psychologically a lot better with disease outbreaks than we are now, because for them, diseases like TB and cholera were simply a fact of life. Every once in a while, something really horrifying like Bubonic plague, would be unleashed, and yes, large portions of society panicked.

    But the thing is we aren't in the 13th century. We not only know how to slow the spread, but we know at least some extent how to take on dangerous pathogens directly. Even three hundred years ago there was some primitive knowledge of inoculating; highly dangerous but at least somewhat effective. Now we have an entire branch of science dedicated towards creating vaccines, and an entire industry built on producing vaccines. The unknown, as much as there is one, is in precisely identifying the effects of the COVID-19 virus, and certainly it's a lot more contagious than cousins like SARS and MERS, but it is a coronavirus, and we know a lot about coronavirus species that infect humans and other mammals.

    ...Huxley's Soma when we need it now more than ever. At least there's cannabis in some places.

  • Then they can't touch you. Can't get blood from a stone.
  • Great ways to deal with anxiety.

    After that start writing, in detail, about what is making you anxious as then your brain will then present you with solutions about what to do about it.

Keep up the good work! But please don't ask me to help.
