If you made a list of things that could advance the field of science, having a mouse watch “The Matrix” and “Star Wars” probably wouldn’t make it to the top. And yet, scientists recently were able to map and render into a 3D atlas a small portion of a mouse’s brain about the size of a grain of sand. The results were a revelation. “"A millimeter seems small, but within that millimeter there are kilometers of wiring," Jacob Reimer, a neuroscientist at Baylor College of Medicine said.

"And this is where we come to our current Secretary of Health, Robert Kennedy Jr. He points at the increase in children diagnosed with autism as a crisis in need of a solution. He blames vaccines for our “disability,” flying fearlessly away from the current scientific consensus. This is incredibly damaging to us, as individuals and as a community, regardless of age or severity.

The vast majority of us -- assuming that we don’t also have other, more disabling conditions -- do not want to be seen as suffering from a mistake. We are who we are not because of vaccines or bad mothering. Our existence is a feature, not a bug. Genetics is the primary cause of autism, if you want to understand why it happened to this or that individual. More generally, autism is one of the ways to be human. The idea that autism can be cured or overcome is as insulting as the idea that gay people can be cured or that to be successful women should act more like men. We don’t want to be cured; we want to be accepted and allowed to be who we are. RFK Jr. stands for the opposite of that. Whether he understands it or not, he is guilty of inciting hatred and self-hatred against our community.

We defy simple categorization. The vast majority of us aren’t intellectually deficient. We have all the emotions and empathize with others. We see allistic social rules and cues, body language and facial expressions, and those linguistic tics and mannerisms that enforce social pecking orders. But other things speak to us more loudly. We’re intensely curious, so we ask indelicate questions. We want to get to the heart of the matter, so we don’t pad our words with softeners. We want the world to make sense, and often go out of our way to make it so, even when those around us don’t notice, care, or do anything about it."

"Misokinesia is a sensitivity to seeing others fidget that is prevalent in the general population"

Misokinesia is an interesting phenomena that I had never heard of before but evidently it is fairly common to various degrees in the general population (about 1 in 3 people have misokinesia to some degree).

nature.com/articles/s41598-021

NatureMisokinesia is a sensitivity to seeing others fidget that is prevalent in the general population - Scientific ReportsMisokinesia––or the ‘hatred of movements’––is a psychological phenomenon that is defined by a strong negative affective or emotional response to the sight of someone else’s small and repetitive movements, such as seeing someone fidget with a hand or foot. Among those who regularly experience misokinesia sensitivity, there is a growing grass-roots recognition of the challenges that it presents as evidenced by on-line support groups. Yet surprisingly, scientific research on the topic is lacking. This article is novel in systematically examining whether misokinesia sensitivity actually exists in the general population, and if so, whether there is individual variability in the intensity or extent of what sensitivities are reported. Across three studies that included 4100 participants, we confirmed the existence of misokinesia sensitivity in both student and non-student populations, with approximately one-third of our participants self-reporting some degree of sensitivity to seeing the repetitive, fidgeting behaviors of others as encountered in their daily lives. Moreover, individual variability in the range and intensity of sensitivities reported suggest that the negative social-affective impacts associated with misokinesia sensitivities may grow with age. Our findings thus confirm that a large segment of the general population may have a visual-social sensitivity that has received little formal recognition.

Here is an example of what #neurology and #PhilosophyOfTheMind are faced with trying to elucidate #Consciousness - that slippery notion of ‘who we are’.

I am neither a scientist nor philosopher, but it seems to me that looking for consciousness in the electrical potential activity of brain cells is never going to explain a whole lot. Imagine trying to explain an electron by solely studying magnetism in excruciating detail as best we can with instruments designed to detect only what we theorise is measurable in a magnetic effect - I.e. to see what we wish to see. That is similar to what neurologists are doing by measuring brain cell activity as a way to identify, and hence classify, consciousness.

In the end, the research may prove fruitful and lead to other discoveries and theories about brain cell activity and the communication channels of the body, but that is the only thing which will be elucidated, brain cell activy - nothing like consciousness (a slippery concept as I said).

The link will take you to the abstract, summary, results and conclusion of the scientific paper, but the paper itself is behind a paywall I’m sad to say (#Grifters have to make money out of publishing someone’s hard work - so dictates capitalism where profit is made from someone else’s sweat and effort, Bah! It wouldn’t be so distastful if $ were extracted only to recoup #publishing costs and wages, but shareholders? Leeches!)

We've incorporated watching foreign language films with subtitles as part of my #Parkinsons Plus MSA occupational therapy. Hearing the foreign language and having to read the words while observing the movie and the characters works different elements and zones of my brain thus "reawakening" brain nerves. #neurology We will do just about any novel therapy to keep the brain and nerves functioning throughout my body.

Now on to the movies: A lot of the movies are independent films.

The big movie studios could learn a lesson from some of these independent films. Enough with all the production room cgi garbage and just shoot a feck'n good story.

We've been watching independent and low budget movies and the difference from a computer-generated editing production with effects added and straight filming is tremendous.

I think the studios exec should watch some independent lgbtq movies. Get back to filming good stories.

Could you imagine what the studios would do to An Officer and A Gentlemen today? Probably enhance it up with unnecessary cgi garbage.

Understanding the health impacts of the climate crisis
and imagining a positive future

"Climate change is the greatest threat to human health now."

"Climate change is already causing significant shifts in weather patterns and an increase in extreme weather events around the world, including droughts, heatwaves, wildfires, storms and floods."

"The major cause of pollution is the burning of fossil fuels, further motivating action on reducing GHG; adverse weather events, such as heatwaves, can acutely amplify pollution impacts."

In 1990, George Franklin was convicted of murder and sentenced to life in prison based on the testimony of his 28-year-old daughter Eileen. Her memory of the murder was relatively fresh at just one year. But the murder happened 20 years earlier. According to the prosecution, Eileen repressed her memory of the murder. Then much later she recovered it in complete detail. The case launched a huge debate between memory researchers who argue there is no credible scientific evidence that repressed memories exist and practicing clinicians who claim that repressed memories are real.

ScienceAlert · Everybody's Heard of Repressed Memories. But What if They Don't Exist?In 1990, George Franklin was convicted of murder and sentenced to life in prison based on the testimony of his 28-year-old daughter Eileen.

Interesting: Research suggests that the human brain starts making long-term memories around 1, even though most older children and adults can't remember much earlier than around 4.

Meanwhile, research in mice (another species that we know experiences the same kind of "infantile amnesia") suggests that corresponding early memories are still present in older mice, just not accessible.

So the next question is, do human brains also still hang onto those early childhood memories, just not in a way that we can get at them?

Just published my first Substack today, and I’m excited to share it with you! It’s also available on my blog. It’s a short read, about 5 minutes long, and there’s even an audio version

Today’s post is called “Left Brain, Right Brain, Who’s the Master?” It’s a philosophical exploration of how the structure of our brains might explain the current crisis in American politics, and what we can do about it. I hope you’ll take a look and let me know what you think!

Humans have been hunting for sex-based differences in the brain dating back to at least ancient Greece. Yet a scientist observing a female and male brain in a lab can’t tell them apart. "I'm not aware of any measure you can make of the human brain where the male and female distributions don't overlap," Dr. Armin Raznahan told Live Science. That said, the question of how male and female brains differ may still matter. @LiveScience has more:

It may be the pain it causes to your teeth or the gross taste in your mouth, but a news study shows that chewing on a hard substance like wood can increase levels of a naturally occurring antioxidant in the human brain. This isn’t to suggest you gnaw on a 2x4, but perhaps chewing on a pencil may improve a person’s memory. @ScienceAlert has more on what dogs have apparently known for decades:
