In Kandel's 2005 book, he lays out 5 tenants to "outline an intellectual framework designed to align current psychiatric thinking and training of future practitioners with modern biology". I regard this as a good snapshot of the "reductionism" that many quibble with, as it is practiced by the neuroscientists who adopt it. Would anyone disagree (either that this is reductionism or that this is a good snapshot of it?). Here are the principles.
Principle 1. All mental processes derive from operations of the brain.
Principle 2. Genes and their proteins are important determinants of the pattern of interconnections between neurons and how neurons function.
Principle 3. Alerted genes do not, by themselves, explain all of the variance of a given major mental illness. Social or developmental factors also contribute very importantly. Just as combinations of genes contribute to behavior, including social behavior, so can behavior and social factors exert actions on the brain by feeding back upon it to modify the expression of genes and thus the function of nerve cells. Learning, including learning that results in dysfunctional behavior, produces alterations in gene expression. Thus all of "nurture" is ultimately expressed as "nature".
Principle 4. Alternations in gene expression induced by learning give rise to changes in patterns of neuronal connections. These changes ... are responsible for initiating and maintaining abnormalities of behavior that are induced by social contingencies.
Principle 5. Insofar as psychotherapy or counseling is effective and produces long-term changes in behavior, it presumably does so through learning, by producing changes in gene expression ...
"’We noted gray matter alterations in both patients with #LongCovid and those unimpaired after a #covid19#infection,’ said [lead study author Alexander Rau]. ‘Interestingly, we not only noted widespread microstructural alterations in patients with long COVID, but also in those unimpaired after having contracted COVID-19.’”
Although I am not a neurologist, I think a lot about the #variants of #PrimaryProgressiveAphasia. I wrote a #memoir about my father's #early-onset #Alzheimer's with #neurologist, #Dr.BruceMiller of #UCSF's #MemoryAndAgingCenter. It explains where in the #brain the initial assault happens and helps us understand why people can't find the right words and/or garble them and/or repeat them. After many years, I learned that my father had the #logopenic variant.
Researchers have mapped how clusters of nerve cells in the brain connect to regulate wakefulness, which could open doors to new treatments for people in comas
I regularly post questions of the day on a variety of subjects (thank you #neurodivergent#brain) but I'm making this one a question of the year bc it is that fundamental to my success as a person.
The reward for contributing meaningful (or humorous) answers to this question will be my sincere appreciation (valued at $0.02 USD).
THE QUESTION:
How can I seamlessly integrate a "lite" tool that operates across platforms (Windows, Linux, Android atm) into my second
I've got a busted consumer product here that has 2 #Holtek#microcontrollers in it. Either one would be sufficient to run this product (a brushless-motor tower fan), but #MCUs are cheap, so why not throw a second one in if it saves a few centimeters of wire?
I'm trying to determine if there's a #standard#serial#physical#layer in use here to communicate from one #MCU to the other. It's one-way communication.
Pretty even-handed assessment of the success and failure of the EU-funded Human Brain Project, which is ending. Probably the most impressive thing is that, given its troubled inception, it produced some meaningful, if rather ad hoc, brain science. #HBP#brain#simulation#neuroscience
Are there any #medical#scientists or #researchers or #neurologists doing any current studies on human #brain & #memory retention - specifically on maximum capacities of human brain memory storage & if there's a limit to how much we can store in our brains?
Like, if we build up many new memories, do we reach a point where some past memories are removed from our memory storage or is there no maximum limits to human memory storage?
These are things I wonder about & don't know enough about.
An interesting overview about #meditation types, and different aspects of the science behind it.
(Personally, I've wondered if it's a type of self-#hypnosis leading to focus, relaxation and maybe tapping into some of the subconscious. though this article doesn't mention anything about hypnosis).
A neurological take on how people end up believing #conspiracy theories -- and then get deeper into them.
Basically, "cognitive linguist" approaches (leaders using the right phrases/words) hack people's brains to get them to form opinions against political targets. Vulnerable people (those feeling uncertainty or fear) relate to what 's said, become less critical -- and real changes are made in the #brain. Those changes become stronger over time and can become more hardwired.
Much of it is about dehumanizing people -- using insults and negative words.
It can happen to people on any part of the political spectrum.
(I think one key is to be skeptical of speeches, articles etc. where insults and a lot of emotional words are used. Plus, watch for wobbly facts.)
In 2020, Swedish neuroscientists put 30 trans and 30 cis research subjects into a brain scanner and showed them pictures of their bodies. Then they showed them images where their body had been morphed to look more masculine or more feminine. The results support the natural order of gender identity.
Here's another reason to get a good night of sleep. Researchers in the U.S. may have found a key to forestalling declines in brain activity that may one day lead to Alzheimer's disease, the most common form of dementia: deep sleep.
