What if there were a drug that allowed us to study consciousness in its most basic form?
Christopher Timmermann describes the potential of 5-MeO-DMT, a psychedelic that strips away everything but awareness.

New paper: "Large Language Models and Emergence: A Complex Systems Perspective" (D. Krakauer, J. Krakauer, M. Mitchell).
We look at claims of "emergent capabilities" & "emergent intelligence" in LLMs from the perspective of what emergence means in complexity science.

today we had a nice discussion on q: 'does Sutton's Bitter Lesson apply to neuroscience?'
Sutton argued that big compute and data lead to AI systems better than any human-crafted alternatives.
Neuroscience has big data now, is it going the same way?

New clues about how the brain avoids ‘catastrophic forgetting’ — the distortion and overwriting of previously established memories when new ones are created. 🧪
Why don’t new memories overwrite old ones? Sleep science holds clues
Research in mice points towards a mechanism that avoids ‘catastrophic forgetting’.

Human cortical pyramidal neurons are larger, with more elaborate branching, and distinct nonlinear biophysical properties compared to rat cortical pyramidal neurons.
Are they more functionally complex? Could that boost the human brain’s computational power? and is that what makes us human? (1/11)
