Thank you very much for remembering and noting my work! :)

Thank you! this doesn’t mean that psychedelics don’t have any effects mediated by membrane receptors in L5p neurons — they probably do, and several. But regarding the reduction of excitatory currents and the emergence of late eEPSCs the intracellular receptors might be crucial

Thank you! I'm happy if our review is useful.

Thanks! Indeed, there are many further possibilities. Let's keep on exploring them!

🙏 I would have stopped working on this a long time ago if there weren't people like you

I'm making some further points in the chapter but probably only three of my best friends are reading this post down here in the thread (and I might lose one of them if I continue) so I just stop here.

🙏 if you got this far.

Sometimes I really hate working on consciousness

This doesn't mean that one cannot capture consciousness computationally at all but we might be really far from understanding these specific computations. The potential space of biological computations is completely unknown to us.

The stupid figure comes from www.sciencedirect.com/science/arti...

As I claim in the chapter, matter matters for the mind. I think the physical brainy stuff matters for the computations. You cannot simply abstract all these details away. The physical properties significantly constrain what types of computations can be run on them. Part of computations is physical.

Third, the most problematic assumption is that we are closing in on the computations of consciousness

The Butlin paper really broke my heart because the key assumption of this paper is that our theories are close to figuring it out. I'm not so sure. We might be really far

Consciousness in Artificial Intelligence: Insights from the Science of Consciousness
Whether current or near-term AI systems could be conscious is a topic of scientific interest and increasing public concern. This report argues for, and exemplifies, a rigorous and empirically grounded...

There is an (implicit) assumption that probably consciousness corresponds to some type of pattern of spiking (the details might be different according to GNWT, RPT and other theories)

But this might be just a historical artifact not a real thing. Spikes might not be the currency of consciousness.

Second, I think our "progress" with respect to understanding the neural correlates of consciousness has been relatively pathetic. Our own theory sucks but it is clearly the best recent theory coming from neurobiology. We must do better! We can do better 💪

First, I acknowledge that consciousness research has made progress but to me that progress has come with constraints: successful theories constrain further progress. What if these theories are not close to figuring out consciousness? Our field was intellectually more fluid 20 years ago. #consci

oh no, these damn humans! 🙂In the first experiments, we explicitly mentioned not to use any external help, but in this second set, which you now played, we didn't explicitly say this, so it is indeed possible that some humans did it. From debriefing we know that many still modeled it in their mind.

Of course, OpenAI updates their models. Our o3 experiments were done in January, so that would be my first guess. We're happy to check this in a systematic fashion in 10 days.
