The Disordered Mind by Eric R. Kandel
What Unusual Brains Tell Us About Ourselves
Nobel Prize recipient Eric R. Kandel investigates The Disordered Mind to uncover what brain disorders reveal about human nature. This challenging study will not only help transform medical care but also encourage a new humanism based in part on the biological confirmation of individuality.

Eric R. Kandel, the winner of the Nobel Prize in Physiology or Medicine for his foundational research into memory storage in the brain, is one of the pioneers of modern brain science. His work has helped shape our understanding of how learning and memory work. Building from this scientific research, Kandel explores one of the most fundamental questions we face: How does our mind, our individual sense of self, arise from the physical matter of the brain? The brain's 86 billion neurons communicate with one another through very precise connections. If those connections are disrupted, the brain processes that give rise to our mind can become disordered, resulting in diseases...
Perhaps the most (in)famous and illustrious American computer scientist and acknowledged principal pioneer of the discipline now known as artificial intelligence (AI), Professor Marvin Minsky of MIT, once pronounced—a belief he still holds—that ‘‘the brain is merely a meat machine.’’ It is significant that the English language distinguishes between ‘‘flesh’’ on the one hand, and ‘‘meat’’ on the other. The latter is dead and may be eaten, thrown in the garbage, fed to pigs, and so on. Flesh, on the other hand, is living matter and, as such, deserves the respect and dignity for life of which, among others, Albert Schweitzer spoke eloquently. The word ‘‘merely’’ in Minsky’s sentence means essentially ‘‘nothing but,’’ that is, also not deserving unusual respect. His statement is a clear reflection of a profound contempt for life that, as I see it, is shared explicitly by important sectors of the AI community, the artificial intelligentsia, as well as many scientists, engineers, and ordinary people. Daniel C. Dennett, an important American philosopher, once said that we must give up our awe of life if we are to make further progress in AI.From Weizenbaum, Joseph (2007).

🧠🧪 We often hear about "dopamine hits" from social media or junk food, but #science shows we've been getting the story wrong. Dopamine isn't the molecule of pleasure – it’s the molecule of anticipation.
This deep dive explains how our #brain actually processes rewards and why understanding the difference matters for our focus and well-being.

Can Psilocybin ‘rewire’ the Brain
Researchers engineered a variant of the rabies virus that was modified to be both pseudotyped and glycoprotein-deficient.
This allowed the researchers to:
- Inject a single dose of psilocybin into mice, followed a day later by the engineered rabies virus into the frontal cortex.
- The virus “jumped” one synapse backward to label the presynaptic neurons effectively mapping the brain’s wiring diagram
- After a week, the researchers imaged the entire brain to compare the connectivity patterns of psilocybin-treated mice versus control mice.

Text Shot: Key Findings
The study, published in the journal Cell, revealed network-specific changes in brain connectivity.
Weakened Negative Loops: Psilocybin weakened connections within the cortex, specifically the recurrent feedback loops associated with rumination and negative thought patterns common in depression.
Strengthened Sensory Pathways: It strengthened connections between sensory areas and subcortical regions involved in perception and action, potentially enhancing how the brain connects perception to action.
Activity-Dependent Rewiring: The researchers discovered that the brain’s own neural activity during the psilocybin experience determined which circuits were rewired. By manipulating activity in a specific region, they could alter the pattern of psilocybin-induced changes, suggesting a potential future for combining psychedelics with non-invasive brain stimulation to guide therapeutic outcomes.
Wait, what if the Many Worlds interpretation is the physical expression of Pilot Wave (icr if theory or hypothesis but whichever)?

#Vacation ended and I went back to #work on #Friday. It was a low key day.
A couple things I've continued to do since starting vacation:
1.) The hour-long solo #winter hikes before work. This has done wonders for my #brain.
2.) Decreasing my "reliance" on #tech. Still using the flip phone for daily comms. My #smartphone is on silent, usage is significantly less, and only check in with notifications and messages a couple times a day.
Not that I am a sedentary person. Quite the opposite but as a #caregiver and #parent for a #disabled #child, self-care time is, by several orders of magnitude, significantly less.

The flyer will get posted when ready, but for now if you're around UCSF on Wed., January 28th from 4:30 to 6 & are interested in hearing us read from & talk about Finding the Right Words: A Story of #Literature, #Grief, & the #Brain, hold that date & time! Bruce is a brilliant #neurologist, writer, & wonderful human being.
3. Ready to get back to writing on #Poe.

Plastics are toxic fossil fuel products. They don't biodegrade, they break up into little bits. And they get into our bodies.
"An examination of the livers, kidneys and brains of autopsied bodies found that all contained #microplastics, but the 91 brain samples contained on average about 10 to 20 times more than the other organs.
The researchers found that 24 of the #brain samples, which were collected in early 2024, measured on average about 0.5% plastic by weight."

Raise your hand if you also like to fool yourself that you can influence a percentage progress indicator by intensely staring at it and really, really wanting it to hurry up.
After all, influencing electronics with your brainwaves is of course very credible. It's uh… you know… quantum mechanics and stuff! 💫

The Idea of the Brain by Matthew Cobb, 2020
The Past and Future of Neuroscience
An elegant & engrossing examination of what we think we know about the brain and why — despite technological advances — the workings of our most essential organ remain a mystery.

For thousands of years, thinkers and scientists have tried to understand what the brain does. Yet, despite the astonishing discoveries of science, we still have only the vaguest idea of how the brain works. In The Idea of the Brain, scientist and historian Matthew Cobb traces how our conception of the brain has evolved over the centuries. Although it might seem to be a story of ever-increasing knowledge of biology, Cobb shows how our ideas about the brain have been shaped by each era's most significant technologies.
During human #brain development, #neural stem cells must balance self-renewal and differentiation to build the #cerebral cortex – the brain’s outer layer responsible for cognition and perception.

COVID-19 will never be like the Flu. Never.
At least not for the brain.
I would love to be wrong; please prove me wrong with evidence and real science!
It is quite simple. #SARSCoV2 can access the brain using several different mechanisms that Influenza cannot.
A: Viral infection of peripheral nerves (like olfactory bulb)
B: Damage of infected endothelial cells
C: Hijacking immune cells
D: Viral opening of tight junctions
Some studies show that some flu strains can use one or other mechanisms, and brain invasion can happen, but it is a weaker and rarer event. The same is true for other viruses.
I have spent hundreds of hours in the microscope looking at the worst viruses can do to the brain, including the Zika virus, HIV, Flu, and others. I've never seen the type of damage SARS-CoV-2 leaves behind after infection with other viruses.
I cannot comment on what happens in other organs, but #LongCovid can be caused by brain damage. It exists and is real.
out of context "aging a brain is bad for it" would that be contentious
research: people who cognitively age well don't have as much cortical loss [1]
"Cortical thickness alterations and systemic inflammation define long-COVID patients with cognitive impairment" [2]
maybe - maybe "superager" brains have not suffered post-viral damage?
or maybe "80 years old with a brain of 50" is just 3 fewer infections that age the organ by a decade each? [3]
