A yr ago, I wrote a piece about what is becoming a quasi-obsession in neuroscience: internal models/representations. I’m kind of stuck and not sure what to do with it. Meanwhile, I came across 2 excellent "critical" papers on the same topic by @olivia.science and @smellosopher.bsky.social 🙏💪 :

REM sleep reduces subthreshold depolarization in cortical pyramidal neurons in a region-specific manner: doi.org/10.1016/j.ce... "NMDA receptors drive subthreshold depolarization specifically during REM sleep."

No GPS in the head? Path integration by entorhinal grid cells without the grid pattern. Interesting paper from Heidelberg. www.nature.com/articles/s41...

The projections still fall short of the 60% reduction in emissions needed to prevent global temperatures from rising by more than 1.5 degrees Celsius above preindustrial levels.

Happy to share our new paper with Mathilde Nordlund and Julie Koenig out @currentbiology.bsky.social. We used virtual reality in mice to study hippocampal distance coding. Our results suggest a primary contribution of grid cells to distance over cue-dependent place cell coding. shorturl.at/63yFo

Vector navigation is common in insects. While directional coding has been studied in great detail, we know less about how distances are represented in the brain. @idatri.bsky.social & S. DasGrupta study the neural mechanisms of odometry in flies. www.biorxiv.org/content/10.1...
