I'm a neuroscientist examining how the human brain enables how we think about the world. Think of our brains as computers (a thought itself!). Then add up all of the computers you've ever owned. Reconstruct the gaps in their use. Consider, rather than electricity, their power comes from food, sleep, and emotion. That's your brain - the computer with more memory than you'll ever know and more precious than anything you'll ever own.

Dad, Neuroscience, Technology.

robg··on You're not lacking creativity, you're overwhelmed
This 1000 times. Why is it that we don’t optimize for brain power? The brain lacking sleep and under stress is designed to survive, not thrive. Our strongest muscle is weakest when we need it most to prioritize survival.

I had forgotten about the best list. It deserves a spot in the header IMO.

robg··on A 1990 experiment to test whether we could discern life on Earth remotely
Karl Ziemelis, now chief physical sciences editor at Nature, handled the paper as a rookie editor. He says it remains one of his favourites — and one of the hardest to get in. Editorial approval for the paper was far from unanimous, because it was not obviously describing something new.

Lesson that the blinders of consensus rarely see what’s new.

I love this example so much because the method was so new and spoke to a key truth. If methods are useful then mundane results are to be expected but still need to be tested. One mentor once said to me that the whole point of an experiment is to test what you think you know. Testing ground truths helps mitigate confirmation biases.

robg··on Ask HN: How do you get out of a rut?
As a neuroscientist who struggles with my brain wellness and health, I’ve developed a checklist for my own self-assessments:

1. How is my sleep?

2. Am I limiting caffeine intake?

3. Anything else affecting my sleep? Room temperature? Lights? White noise? Eating too late? Alcohol?

Sleep is how the brain repairs damage caused by daily life. Not enough or poor quality means you will drag, not just over days, but weeks and months is exactly a downward spiral.

4. Checked my Vitamin D levels recently and supplementing with D3/K?

Circadian rhythms and cognition are poorly studied, but there’s good evidence on Vitamin D and mood and seasonal affective disorder.

5. Managing stress?

Too much stress affects key brain functions like learning, memory, and attention. Too little sleep leads to more stress.

6. Exercising enough?

Am I getting outside daily, going for walks or runs, etc.

7. Nutrition

Am I making good food choices that give me sustained energy or am I eating mindlessly?

The pandemic was the last piece on nutrition for me. I saw how one bad meal (e.g. burger and fries) affected me for 2 days.

robg··on Support for Third U.S. Political Party Up to 63%
P.s. Arizona could be a good test of the theory in the next Senate campaign, albeit with an incumbent going third party.
robg··on Support for Third U.S. Political Party Up to 63%
Same problems? I don’t see that, it’s a local-ish constituency powered by national trends. States like New Jersey, Maryland, and Massachusetts all regularly flip governors between the two parties. Adding states like Colorado, Arizona, Delaware, New Hampshire, etc isn’t crazy for down a middle agenda.
robg··on Support for Third U.S. Political Party Up to 63%
Folks jump to the presidency, but seems like the biggest value prop for a third party is winning a few Senate seats. Target 10 smaller, purple states with one major media market. 2-3 wins in one year gives six years to build momentum.

With each added Senate seat in subsequent years, the third party builds relevance by setting the Senate agenda. Given how evenly split the country is, just a few Senate seats have outsized influence. House is possible too, but with only 2 year terms, the value is harder to maintain and build upon.

robg··on We’ll call it AI to sell it, machine learning to build it
When can we harmonize the two and call it “Statistical Learning”?
robg··on Before psychedelic therapy for wartime trauma, there was narcosynthesis
Should content moderators get psychedelics as part of their work demands?
robg··on Before psychedelic therapy for wartime trauma, there was narcosynthesis
The literal shock to the adrenal system with trauma is this century’s cancer. We see it as decreasing expectancy of the last 30 years in the U.S. The fight for survival is a basic instinct that needs to be managed with holidays, nature, and recreational pursuits. With AIs will we learn to work and fight smarter? Even drone pilots get PTSD.
robg··on Google changed ad auctions, raising prices 15%, witness says
What laws did they break? I’m confused by the sudden interest in monopolies when the duopolies have developed over 20 years. It’s like after Microsoft government assumed Google / Facebook and Google / Apple and EBay / Amazon had each other so all was good?
robg··on Indoor wood burning raises women’s lung cancer risk by 43%
It’s amazing to me that active air exchanges for filtering and even humidity are not well optimized as part of modern housing HVAC. Is it costs or simply system integrations?

For instance, another big indoor pollutant is cooking fumes, from both the heat source and to cook, carmelize, burn, etc - the food and vapors of changing temperatures. The range hood required by fire codes to stove sizes is not turning on automatically with pollutant detection.

If you have to choose, going to get caffeine or a nap, choose the nap.

Best is to caffeinate then nap.

robg··on The brain is not an onion with a tiny reptile inside (2020)
The biggest I’ve seen is that talk therapies don’t work well if an underlying sleep concern is not addressed. Sleep as the parasympathetic nervous system is predictable from a more primitive model whereas a cognitive - behavioral model assumes thoughts can drive recovery.
robg··on The brain is not an onion with a tiny reptile inside (2020)
The autonomic nervous system is real biology that most psychologists don’t start with. While this article is based on textbook descriptions of the evolution of the brain in the skull, not seeing much on how the autonomic nervous system is primal specifically for survival.
robg··on The brain is not an onion with a tiny reptile inside (2020)
Especially since the master reptile - the adrenal cortex - is located atop the kidneys. Fight or flight is first an electrical relay to the hands and feet and heart. The brain in the skull and consciousness reflects upon what’s already happening in the periphery.
robg··on DeepMind cofounder: Generative AI is just a phase. What’s next is interactive AI
Brain implants feeding off our sensory and cognitive circuitry seems the century long challenge. Robots and bots are interesting distortion mirrors along the way.
robg··on DeepMind cofounder: Generative AI is just a phase. What’s next is interactive AI
Does anyone have recommendations on people pointing out the wide epistemological limits of current and future datasets?

I’ve been thinking about the limits of statistical AI for the last 20 years when I did my Ph.D. in embodied cognition. Folks like Andy Clark then put much more emphasis on having bodies.

robg··on Breakfast cereal is in long-term decline
Trash food deserves to be in the trash heap of history.

That said, it’s great humanity learned to produce more food than we need then ways to process and store it for years later. Hopefully we’l never need that knowledge again.

robg··on The Uselessness of Phenylephrine (2022)
My kids seem to derive benefit from chewable tablets which I tell them to suck on. Curious if anyone has found different research on metabolization in the mouth versus gut?
robg··on What is an emotion? William James’s theory of how our bodies affect our feelings
Fun fact: William James was a professor of physiology at Harvard. Now William James Hall is a literal and figurative ivory tower on campus. How many students are taught that the status of the brain in their body affects learning, memory, attention, and critical decision making?
robg··on What is an emotion? William James’s theory of how our bodies affect our feelings
Unfortunately the neurosciences diverged in the 1940s and 1950s when lobotomies became increasing common and emotions got tied to what you said based on what you felt. Psych-sciences have been apart from the neurosciences ever since. Better techniques like fMRI and EEGs have meant more data that’s not getting used in diagnosing and treating diseases.

Meanwhile the adrenal cortex and the autonomic nervous system has been largely forgotten. It regulates how we feel every second of every day, even when we are asleep. Good luck being happy when you are overstressed and underslept.

How many hours have gone into developing technologies for better ad targeting and yet still the same playbook for social media revenues? Has the approach of sucking up more data about you changed in 10 years? I get it’s been very profitable…
