Brains, attention, memory, perception, neurodivergence and why people do inexplicable things.
Can You Really Have “Low Dopamine”? What Tests and Supplements Can’t Tell You
A checklist of “low dopamine symptoms” can feel uncannily accurate. It still cannot measure a neurotransmitter, diagnose ADHD or tell you which treatment will work.
Is Intuition Really Pattern Recognition? Here’s When to Trust It
Your brain can learn regularities you cannot explain, and experts can spot a useful “gist” in half a second. But confidence cannot tell trained skill from bias.
People keep dreaming of ‘Mall World.’ Has anyone compared the maps?
People independently report recurring dreams of malls, hotels, airports and impossible connected interiors. The real test is not whether the motifs overlap, but whether anyone’s maps do.
Does histamine cause ADHD? The molecule’s location matters.
Brain histamine matters for attention. That does not make ADHD a body-wide histamine excess, a DAO problem or a condition proven to respond to a low-histamine diet.
ADHD isn’t a simple dopamine deficiency. So why do stimulants work?
The treatment is not the diagnosis. Imaging, genetics and genuine dopamine-deficiency disorders point to timing and circuits—not an empty chemical tank.
Why does not knowing itch? Not every gap gets under your skin.
Curiosity is not a universal dislike of uncertainty. The strongest itch begins when you can see a specific, valuable gap—and think the answer is within reach.
Remembering can change a memory. But what opens it for editing?
Recall is not an automatic overwrite. Surprise may open some memories for updating—but a large mismatch can become a separate episode instead.
