After 20 years studying neuroscience, I can confidently say that the brain is up to something.

cause cortex is just a blanket to keep the basal ganglia warm
January 2, 2026 at 11:55 AM
Way back in 1999, Kenji Doya sketched a big picture theory of the brain:

1️⃣The cerebellum is specialized for supervised learning
2️⃣The basal ganglia are for reinforcement learning
3️⃣The cerebral cortex is for unsupervised learning

How does this hold up in 2026? www.sciencedirect.com/science/arti...

Why procrastination isn’t laziness – it’s rigid thinking that your brain can unlearn
Why we procrastinate has less to do with willpower than with how flexibly our brains handle stress and discomfort - and the good news is, flexibility is trainable.

This is quite funny:

Remember how Springer Nature decided to retract nearly 40 publications based on a ‘bonkers’ and unethical autism dataset? www.thetransmitter.org/retraction/e...

Well, they just today published a new paper using the same dataset! www.nature.com/articles/s41...

Given that the cerebral cortex seems to be capable of flexibly learning so many tasks, why is it that we need so many other brain regions?

What are the hippocampus, cerebellum and striatum doing that the cortex can't do?

Maybe the cortex is less flexible than we think?

Why do we experience vision and hearing as distinct senses?

The obvious answer is that they have different sensory organs (eye vs. ear), and their signals arrive at different points in the cortex (primary visual cortex vs. primary auditory cortex).

But does that really explain it?

Would you intuitively agree with this statement: If we are conscious of something, it can affect our decisions?

(Note - don't confuse this with the contrary statement that 'something can only affect our decisions if we are conscious of it', which is clearly false)

FDA approves pill form of Wegovy (semaglutide) weight-loss drug www.bbc.co.uk/news/article... This is big, no?

Once these drugs get cheap & convenient enough for mass use, obesity rates will start falling. Will history remember 1990s-2020s as the "age of obesity"?

The word "decision" is a key word in cognitive neuroscience. But what does it mean exactly?

People's intuitions seem to differ on what "decision" means.

For example: do animals (say, cats) make decisions? Most people would say yes, but I think some would disagree.

Do plants make decisions?
