Abstract: Reinforcement learning (RL) enables adaptive behavior across species via reward prediction errors (RPEs), but the neural origins of species-specific adaptability remain unknown. Integrating RL modeling, transcriptomics, and neuroimaging during reversal learning, we discovered convergent RPE signatures - shared monoaminergic/synaptic gene upregulation and neuroanatomical representations, yet humans outperformed macaques behaviorally. Single-trial decoding showed RPEs guided choices similarly in both species, but humans disproportionately recruited dorsal anterior cingulate (dACC) and dorsolateral prefrontal cortex (dlPFC). Cross-species alignment uncovered that macaque prefrontal circuits encode human-like optimal RPEs yet fail to translate them into action. Adaptability scaled not with RPE encoding fidelity, but with the areal extent of dACC/dlPFC recruitment governing RPE-to-action transformation. These findings resolve an evolutionary puzzle: behavioral performance gaps arise from executive cortical readout efficiency, not encoding capacity.

The Ackermann family claims to be descended from French kings, posts QAnon type screeds, and has fascinatingly bad taste in just about every aspect of life there is.

- Sayo Yamamoto ("Michiko & Hatchin"; "Yuri!!! On Ice")
- Mari Okada ("Ano Hana: The Flower we Saw That Day"; "Toradora!")
Game designers/programmers:
(Upon review I was pretty remiss in skipping over a few of these people, some of whom I wasn't aware of but most of whom I just didn't remember when writing my short list. Subconscious misogyny in action. Short & Thorson probably would have squeezed out some of the YA authors I included, although I have no real regrets.)
- Junko Kawano ("Suikoden")
- Elizabeth LaPensée ("When Rivers Were Trails")
- Momo Pixel ("Hair Nah")
- Zoë Quinn ("Depression Quest"; narrative designer on "Solar Ash")
- Kellee Santiago ("Cloud"; "Flower")
- Tanya X. Short ("Moon Hunters")
- Kim Swift ("Portal")
- Maddy Thorson ("Celeste")
- Andi McClure @… ("Jumpman")
Note: I haven't included composers or artists here, but there's a deep bench.
Games journalists/steamers:
- Tanya DePass @… (#/INeedDiverseGames; twitch streams)
- Anita Sarkeesian (Feminist Frequency)
Game/play scholars:
- Mary Flanagan ("Critical Play")
- Tracy Fullerton ("Game Design Workshop")
- Brenda Laurel ("Toward the Design of a Computer-Based Interactive Fantasy System")
- Janet Murray ("Hamlet on the Holodeck"l
- Susana Tosca ("A Pragmatics of Links")
- Jichen Zhu ("Agency Play: Dimensions of Agency for Interactive Narrative Design")
- Magy Seif El Nasr ("Design patterns to guide player movement in 3D games")
- Kate Compton ("Causal Creators"; also "Spore")
P.S. upon consideration I've decided not to include any authors who are men in this coda.
There are definitely others who probably deserve to be here that I'm forgetting...

Today's puzzle in #AdventOfCode was another grid puzzle, where I again represented the entities as a sparse set.
Part 1 was relatively straightforward, a simplified BFS-like process allowed to construct the beams going through the system.
For part 2, additionally to gathering where a beam was present, I added metadata about how many paths were going through each position, adding them up and splitting them as required. Summing the paths for the last row gave the required result.
