Allodynia is a state in which pain is elicited by innocuous stimuli, for example in response to cutaneous capsaicin application. This phenomenon is mediated by spinal cord /1

Options are first encoded in orthogonal subspaces Then the selected option rotates into a "readout subspace". Neural subspace reorganization reflects value-based decision making. www.biorxiv.org/content/10.6... #neuroscience

- Reposted by neurophysicsI recommend this as a great summary of the debates and the state of play in eukaryotic regulation. I particularly commend the discussion of causation.

- Reposted by neurophysics1. The thing about science that these jokers don't understand is that science cannot be vibe-coded. Whatever its flaws, the point with vibe coding is that you're trying to quickly make something that sorta works, where you can immediately sorta see if it sorta works and then sorta use it.
