biased because I just saw Diego Bohórquez give a very impressive talk but any of his work on gut-brain connections (e.g. www.science.org/doi/full/10....)
A gut-brain neural circuit for nutrient sensory transduction
A neuroepithelial circuit that connects the intestinal lumen to the brain stem in one synapse has been identified.

for broader terms like "intelligence", I'm not sure. it's why I avoid these sorts of terms completely. it probably changes depending on the field, but if these terms emerged out of human-focused work then there will always be people that don't think they apply to non-human processes

I would say yes... based on the logic that what we want to understand is what humans do, so we come up with a term to describe a process, then we come up with measures that capture that process (imperfectly). I think it matters when using that term that we are describing the same process.

I think you can get at different aspects of the process by looking at neural activity vs. behavioral paradigms. But I think something could do well at certain episodic memory tests with a process that varies significantly from what people that study it in humans mean when they use the term.

I guess I use episodic memory as an example because I believe the tests are a particularly lazy proxy of the process that are good at picking up major dysfunction but miss a lot else (which is why many people studying episodic memory as a process don't use these basic tests in their work).

I think we have a range of measures of outcomes and a range of measures of process, and some combination of those (depending who you ask) would comprise episodic memory. I do think that the process is part of our definition of these terms (although we've often forgotten this in human research too).

I sort of agree, but is the operationalization of a concept all it is scientifically? I wouldn't use "intelligence" when studying humans or AI (too broad and poorly defined), but if AI can do episodic memory tasks, does it have episodic memory? I would say no...

Really interesting work! How do you think this relates to "events" (rare, high fluctuation time-points) in fMRI? I know there was a back-and-forth debate a few years ago about what types of signals were driving fMRI FC:
www.pnas.org/doi/full/10.... www.sciencedirect.com/science/arti...
BOLD cofluctuation ‘events’ are predicted from static functional connectivity
Recent work identified single time points (“events”) of high regional cofluctuation in functional Magnetic Resonance Imaging (fMRI) which contain more…

Just continuing the long-standing scientific tradition of prioritizing cool-sounding names for things over clear science communication 😅

Something like this? Source: jtr13.github.io/cc21fall2/ra... but then it doesn't look like a raincloud... (original raincloud plot source pmc.ncbi.nlm.nih.gov/articles/PMC...)

This is a ready-made advert for raincloud plots
