In the 1950s, researchers stumbled upon a new class of drugs that provided relief for those suffering from schizophrenia. These drugs were known as antipsychotics and, as the name suggests, they reduced symptoms like hallucinations and delusions primarily by reducing the levels of dopamine in the brain. This led clinicians and scientists to argue that dopamine was linked to the experiences of psychotic symptoms, and a concerted research effort ensued, seeking to solve the puzzle of why excess dopamine might produce hallucinations.
Although it was later shown that increasing dopamine could produce hallucinations, establishing a consistent link between them, it has not been clear why.
They achieved this by taking advantage of a simple fact: Your brain is lazy. It makes shortcuts to understand the deluge of information that bombards it daily. If youre presented with consistent information, consistently, your brain adjust its expectations of reality in turn. This is the basis of Bayesian theories of how we perceive the world that is, the brain makes inferences about the world around us based on statistics and probabilities on what is likely to occur.
[I]ncreasing dopamine made it more difficult for participants to adjust their perception an effect comparable to how the hallucinators had struggled. Moreover, the extent to which participants struggled was strongly associated with the severity of hallucinations but not with any diagnosis of schizophrenia. In other words, the difficulty appeared to be associated with a symptom, not a diagnosis.
Using brain imaging, the researchers also showed that an increased capacity for dopamine release, from a part of the brain known as the striatum (an area involved in schizophrenia), was associated with the severity of hallucinations. Together, these experiments showed that excess dopamine was associated with difficulty in accurately predicting reality.

What a relief!
Hey..
That's a line from that famous hit song that starts "Plop, Plop, Fizz, Fizz. Oh what a..."
It's called "hamburger."
That Morning Floof is so cuddled! And looks so at peace.
My daughter and her Rob’t added a new tuxedo kitty to their herd. It ran straight for them when they opened the door to go out during the snow storm yesterday. Maybe two months old, and thin. No word on a name, yet, but she should fit in just fine with Merlin (marmalade) and Binxx (solid black.)
First thing this morning, I had to sort my pills. Now I’m tired. Go figger.
It’s good for a kitten to have a friend. I hope the new one works out well for your daughter. Snowstorm, Gah.
Drama Queen got in from work just a little while ago. She says she’s scheduled for 40 hours this week.
Currently 31° headed for a low of 23°. The high will be 52°. I need to buy thick gloves this year. The ones I have are like no gloves at all.
I get the 2-pairs-for-$1 knit gloves at Walmart, because we always lose everything.
Maybe I’ll ask my Christmas buyer to get me some actual warm gloves.
Back from putting gas in the Avalon for That Other Driver. She should be out of debt to the Organization by the end of November, and then I’ll start charging her the full rate for her auto insurance. Zot!
But only a mini-zot compared to what Tom the Son is going to find when he has to get his own policy for his own car.
Vlad and I finished the Wall Street Journal crossword. It was hard, for a Tuesday, because several of the long DOWN items had only “See Header” for the clue.
We need to leave in 15 minutes for WW, because I need to get gas in the van.
It will probably be Thursday before I can get together with Asuncion regarding ideas for purple jewelry. Meanwhile, if you want to Google “purple bead jewelry,” you might see something that appeals to you.
Ask your Christmas Buyer to get you “ski gloves.” They’re the only ones that will keep my hands warm.
I have the 2-pairs for $1 and they are worth just about a dollar when it comes to warmth.
Off to WW. Seeya later!
I believe that commercial was also famous for introducing heart-shaped meatloaf.
Happy Tuesday.
Kitteh is treating the day the way it should be treated. For those of us who can’t cuddle a stuffed animule all day I got nothing to offer. I wish I did.
I see three Beatles and a VW. You seein’ dead folks?
Sometimes...
I’m back. What did I miss?
Not sure. What were your targets?
It's been a truly unexciting Tuesday morning here, which isn't such a bad thing. It has, however, made the crawl to post 200 a little slower.
Next person to drop by will win.
HA!
