Happy to share my new paper, out today in nature. I developed a single-cell approach to trace inputs and manipulate the activity of individual place cells in CA1, which revealed how neurons are embedded into specific and recurrent subcircuits. nature.com/articles/s4158…

Excited to share some of my postdoc work as a bioRxiv from the Harvey lab Harvard Medical School. We show that mice rely on different cortical areas for navigation decisions, depending on what other complex tasks they have previously learned. Training history matters!

The brain is built on a principle of division of labour, where anatomically distinct regions perform specialised tasks. But how are messages sent round the brain allowing regions to communicate? Read on and see our preprint to find out the answer! biorxiv.org/content/10.110…

Great to see another piece fall into place in the puzzle of “what makes some neural activity perceptible”!

Ever wondered how hippocampus 𝒶𝒸𝓉𝓊𝒶𝓁𝓁𝓎 learns successor representations? Our new preprint has some ideas and you should check it out. Credit to the amazing Will de Cothi Kim Stachenfeld (neurokim.bsky.social) and @caswellcaswell. Thread coming soon... biorxiv.org/content/10.110…

Out today – all-optical interrogation lore from ~10 years of work (and thousands of postdoc and student hours) compressed into a single Nature Protocols article! rdcu.be/cMeO2

Proud to have our all-optical protocol piece out today in Nature Protocols. This was many years, 10s of burnt fluorescent slides and 1 broken 2P laser in the making. What a team to have worked with.

This.

Big up the Barry Lab 🔥

Come and visit me #FENS2022. I'm showing some of my PhD work on sleep mechanisms that support skill learning. Its my first conference poster ever so I will be very enthusiastic I promise! Poster session 2 on Sunday afternoon - 10/07/22 Board S02083 SWC M Stephenson-Jones

Can someone spot me FENS access to see this one?!🔥

Where did the pandemic begin? Was it from nature or a lab? Since the start, this fundamental question has gone unanswered. Until now. Out in Science Magazine: SARS-CoV-2 emerged into humans via the live animal trade at the Huanan Seafood Market. science.org/doi/10.1126/sc…

Common Pandas problem: You have a big dataframe and a function that can't be easily vectorized. So, you want to run it in parallel. Surprisingly, most answers on StackOverflow just point you to a different library. So here's a little recipe I use:

My final piece of PhD work is finally out! I teamed up with Chris Harvey, Mike Greenberg Michael E. Greenberg, and Lynn Yap Lynn Yap to investigate Fos expression in the context of spatial memory. I recap some of the main results below! 1/N nature.com/articles/s4158…

I was watching that new Rings of Power show, and the opening credits have these abstract shapes forming and reforming in sand. They seemed strangely familiar, and I suddenly remembered I'd seen them before, they're Chladni figures! (1/x)

Please reach out if you are a masters or PhD student (apply through NeurosciencePhD_EPFL!) with research interests in large-scale neurophysiology, virtual reality, computational modeling, and the neurobiology of memory! Retweets appreciated!

A major problem with marketing AI for general use is that it’s so easy to forget that authors only ever show us Figure 1A. It should be a legal requirement to show us the rubbish in Supp. Fig. 13J…

Beautiful visualisation of an ugly message - same time period, economically similar peers, repeatable across epochs - Tory rule bleeds us dry.

If people can manipulate Bing/ChatGPT (and similar) to use aggressive language, despite creators’ best safeguards, embodied versions of such systems will be able to kill. Asimov’s Laws don’t apply when you’ve no idea which edge to cut or which node to silence.
