Great piece by @evanthompson.bsky.social arguing that viewing consciousness as a "controlled hallucination" is self-defeating. Similar to how @seanmcarroll.bsky.social argues against Boltzmann brains. If experience is a controlled hallucination, then that theory is a part of the hallucination /1

Do you work or study in the fields of psychology, neuroscience, computer science, artificial intelligence, or philosophy? What does the term 'representation' mean to you? We invite you to participate in a brief survey on key conceptual questions across fields. eu.surveymonkey.com/r/VX9GNXM

How can we best learn about the world? A new paper by SFI's Marina Dubova (@mdubova.bsky.social) and coauthors applies the scientific method to itself, finding that some common strategies that scientists consider gold standards for designing experiments could perform worse than random choice.

Stanford CS researchers just got a huge payday for promising AI agents that can simulate the real world. @mjcrockett.bsky.social and I wrote about these researcher's vision. Screen shotting quite a lengthy part of our paper, because we spent A LOT of time thinking about the paucity of this promise
/1 Here's yet another study on the thalamus in PTSD! We show that PTSD patients display different patterns of connectivity between the thalamus & cortex. Different nuclei displayed different patterns of altered RSFC.. #neuroskyence #neuroscience #science #fMRI www.sciencedirect.com/science/arti...

“'The guy, I’m telling him like, "Please step off the school grounds," and this dude comes up and bumps into me and then tells me that I pushed him, and he knocked me down,' an official at Roosevelt High School said. 'They don’t care. They’re just animals. I’ve never seen people behave like this.'"

This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!
Would love to hear expert views on this paper. It appears to show that the operationalization of brain activity the field has relied on for 3 decades—the BOLD response—is not actually a sensible measure of brain activity. www.nature.com/articles/s41...

How is the thalamus impacted by trauma? The thalamus is more than a relay - it is a key node in perceptual, cognitive, and affective processing circuits. We found that the limbic thalamus has lower volume in both PTSD and MDD, while the sensorimotor thalamus has lower volume in PTSD only /1
