Excited that our paper, “The limbic navigation system as a hierarchical RNN”, has been accepted at #NeurIPS! Joint work with two talented students, Huiwen Zhang, Krishna Gorantla, and @neilburgess10.bsky.social. We use a multi-module RNN to explore how the brain’s navigation circuits works.

Thanks Caswell! Happy to see this out. Recent interesting work from Vollan et al @azvollan.bsky.social showed that the decoded locations from grid cell activity sweep out in a left-right alternative way across successive theta cycles, steered by an “internal direction” signal in parasubiculum.

Phase Precession Relative to Turning Angle in Theta‐Modulated Head Direction Cells
Grid and place cells typically fire at progressively earlier phases within each cycle of the theta rhythm as rodents run across their firing fields, a phenomenon known as theta phase precession. Here...

🧠 Our new (NIH funded!) paper reveals how the brain creates internal dynamics during both real- and imagined navigation. We recorded directly from the human hippocampus as participants moved through physical space and when they mentally navigated imagined routes. www.nature.com/articles/s41...

This is cool! As a CCN student (2017) and a TA during the pandemic (2021), I highly recommend. It is also a good opportunity to explore China. CCN will happen again in Suzhou this time, which is a famous historical and cultural city in China.

Ha ha. I am indecently excited by this! I think there are so many amazing neuroscience stories that don’t get told it’s great to be able to show some of them off! I hope the kids (and adults!) that read this will be as excited as I am about the way the brain works.

Very happy to see this out! Based on the microcircuit identified by Vollan et al., we made some interesting predictions about theta sweeps along the parasubiculum-MEC-HPC pathway, especially theta modulated head direction cells which direct the left-right sweeps in downstream grid cells.

I have been reading about cognitive maps and finding this literature fascinating, in particular that they could be reused to generalize. But is there really evidence for this? More generally, IYO what piece of evidence is missing to demonstrates the brain uses CM in important ways? Please RT🙏

Happy head direction cell day y’all! On this day, 41 years ago, Jim Ranck recorded the first “HD cell” in his Brooklyn lab in 1984. Jim shared the news with the world at SFN that year, showing a video of the cell’s firing on a TV he somehow acquired and brought to his poster… (1/3)
