"the brain" Can any of this grand top-down 'delusions and personality traits are thermodynamic xyz' theorising about "the brain" apply to, say a bee's brain or a worm's?

[coldtea]

Two facile answers:

1) Yes. Why couldn't it?

2) No, it requires a certain level of brain complexity.

Regarding complexity: Probably anything with a brain has the problem of balancing lots of different sources of information and maintaining (enough) coherence of behavior. So even very simple worms will need a simple version of this...

[jedharris]

Hard to identify delusions in worms. But the entropy / free energy models work for the best understood worm brain (C. Elegans).

Specifically, "Signatures of criticality in a maximum entropy model of the C. elegans brain during free behaviour" <http://cognet.mit.edu/proceed/10.7551/ecal_a_010> and I'm sure many more.
