“The mind is its own place, and in itself can make a Heav'n of Hell, a Hell of Heav'n.”

John Milton

Some of the opinions being said about ChatGPT tell us more about the opinion holder than about ChatGPT.

The purpose of models is not to fit the data but to sharpen the question.

Dear fellow scientists, feel free to promote your best work a bit more on here. It might feel three years old to you, but I might have missed it, or I have forgotten about it (which has more to do with my memory limitations than the quality of your work!). I might have moved on in my interests and your work is now something I should really read. Or I just need that fifth reminder to finally actually open that pdf in my reading folder!

Yes, interesting and unexpected. Rythms are everywhere, even in plants, and there are circadian ones, breathing ones and neural oscillatory ones of different frequencies. And we don’t understand them.

In early PET and then fMRI studies we showed activation in prefrontal cortex when people decide which finger to move. So we claimed that this reflected decision making. But the activation was measured across many trials in a session. Very many years later James Rowe who did his PHd with me showed that there was no such activation on a single trial and that that was not due to low power (over 50 people). So the activation reflects taking the last trial into account.

anyone else find that the standard ‘plot’ for scientific paper abstracts is a lot like standard movie plots:

- set the scene, everything’s fine
- OH SHIT, that was an unexpected thing
- characters realise they are going to have to get off their asses and DO SOMETHING ABOUT THIS
- bunch of significant things happen
- sunny outlook… until next time

Absence of occupation is not rest,
A mind quite vacant is a mind distress'd.

-William Cowper (1731-1800)

“The last thing we discover in composing a work is what to put down first.”

Blaise Pascal

Even when we are quite alone, how often do we think with pleasure or pain of what others think of us - of their imagined approbation or disapprobation...
