😹🧠 Have you ever wondered why it’s so hard to stop laughing once you start?
While voluntary laughter is a controlled social tool, involuntary laughter is triggered by the amygdala and releases feel-good chemicals called endogenous #opioids – which explains why we are 30x more likely to laugh in a group than when we are alone.

A #Brain #Chip, formally known as a Brain-Computer Interface (BCI), is an implantable device designed to bridge the biological nervous system with digital computers.
These chips typically use an array of micro-electrodes to detect the electrical firing of neurons, translating those signals into commands that can control external software or prosthetic limbs.

#KnowledgeByte: The human #Brain, a three-pound universe of interconnected neurons, is the most complex structure known, orchestrating everything from basic survival to abstract thought.
It's the seat of consciousness, creativity, and individuality, making each human brain a unique and marvelously intricate masterpiece.

The medical-writer part of my brain says this shows incredible promise for ways to target and treat neurological conditions. The science fiction part of my brain sees a bunch of potential nefarious uses such as inhibiting fear and empathy in super soldiers, or some level of mind control.
Of course, this is all distant-future stuff. First they have to finish mapping the mouse brain. There are a lot of steps yet and it's all super complex.

🧠💻 Can biological cells out-think silicon chips? Scientists at UC #SantaCruz have successfully trained lab-grown #brain organoids to master the "cart-pole problem," a fundamental task in #AI.
By connecting these organoids to a virtual environment, they’ve shown that living tissue can learn and adapt to solve #engineering challenges in real-time.

Endocannabinoid-System
Das Endocannabinoid-System (ECS) wurde 1992 entdeckt. Es ist der Grund, warum Cannabis im menschlichen Körper wirkt. Es reguliert im Wesentlichen alle grundlegenden Funktionen und Muster, die unser Körper auszuführen hat und hält ihn im Gleichgewicht. Lesen Sie mehr über diese bahnbrechende Entdeckung, die leider immer noch nicht im Medizinstudium angekommen ist.

"Expert birdwatchers have brain differences that may underlie their remarkable ability to identify unfamiliar birds and suggest that birdwatching can reshape the brain in much the same way as learning a language or a musical instrument does."
🧠🐦 It turns out #birding is more than just a quiet hobby – it’s a high-intensity workout for your #brain.
Scientists found that the expert knowledge needed to tell similar #birds apart creates a "mental scaffolding" that strengthens your memory and might even help protect your brain from aging.

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.

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.
