🕷️💤 New paper in time for 🎃! Do #spiders really sleep? In our new study on #Portia fimbriata we tested all behavioural criteria of #sleep and found evidence for regulated, two-stage sleep with recurring REM-like stages. Out in @pnas.org! @roesslerdaniela.bsky.social 📄 tinyurl.com/3fky8ze7 🧵1/9

🚨 New preprint! REM Sleep Iota Oscillations Across the Lifespan 🧪💤 #sleep @snipeso.bsky.social analysed high-density EEG from 578 people aged 7–70 to investigate iota oscillations and explore how the brain changes across the lifespan. doi.org/10.64898/202...

Can less cognitive control help us learn? I'm excited to share our new Cell Reports paper. Using inhibitory rTMS in 95 adults, we found that inhibiting the right DLPFC—or both sides—improved learning of hidden statistical patterns. Inhibiting the left alone did not. www.cell.com/cell-reports...

Synchronization in the visual cortex is coordinated with hippocampal sharp-wave-ripples during awake immobility. The effect is stronger in high cortical synchrony and constricted pupil phase.

After a long journey it's finally out! My work on navigation strategy-dependent hippocampal representations during plnning with Richard Morris is out on @natcomms.nature.com ! rdcu.be/iS72dYSzBxya

Interesting new study from the Frank lab: Hippocampal representations of alternative possibilities are flexibly generated to meet cognitive demands

New paper from the Neurosurgery Research Team at BCM! “Neural geometry in the human hippocampus enables generalization across spatial position and gaze” led by @assiachericoni.bsky.social! 🧵 www.cell.com/neuron/abstr...

Apply!

Now in Science: How does the brain’s navigation system allocate its limited representational resources during behavior? We found that grid cells sweep toward locations of interest, providing a potential mechanism for allocating spatial attention in the cognitive map.🧵 science.org/doi/10.1126/...

A really interesting new two-photon miniscope study for all the retrosplenial geeks out there! Anterior and posterior retrosplenial cortex employ distinct strategies for egocentric–allocentric transformation in spatial coding

***New preprint from the lab*** showing “Generative replay across hippocampal-neocortical circuits”. In sleep we show spiking sequences in V1 (sensory neocortex!) that represent information that has not been directly experienced www.biorxiv.org/content/10.6... @bndu.ox.ac.uk @ndcnoxford.bsky.social

Cool work on the HPC and activation of context representations in the prefrontal cortex 🧪

🧠 BOARD, Be Open About Animal Research Day, is a global, 24-hour social media campaign created by the @eara.eu, which celebrates openness by biomedical institutions across the world in communicating animal research.

Join us tonight, at FENS Forum, Hall H, starting with 18:45! #FENS2026 h1.nu/1yJG2

We're finally getting the tools to study replay in humans. But why bother? What can we learn from it that we don't know from rodent recordings? Our thoughts are now out in a new TICS Forum Great fun writing this w @smfleming.bsky.social + @maritpetzka.bsky.social authors.elsevier.com/sd/article/S...

We are proud to introduce the new FKNE Scholars!

Larry can be on my team. Hell, *I* want to be on Larry’s team.

Our @fens.org Satellite meeting is tomorrow! #FENS2026 Check out our updated program👇 youngpisymposium2026.com/program/ We are all super excited to have everyone joining! Safe travels everyone 🚅 ✈️ 🚲 See you in Barcelona 🔆😎

On the way to #FENS Forum! Come by, we have a symposium (Beyond episodic memory: engrams for feelings and facts Thursday 9:45 Hall D) and posters (Thursday 14:00-17:30 PS06-09PM-466-8) on learning complex multi-trial tasks spanning species (mouse, rat, human). See you there!

Some neurons like to ride on slow LFP oscillations, regardless of their phase! This might represent a mechanism to coordinate neural activity and propagate information across brain circuits 🧠 amazing collaboration led by the super talented @zahrajourahmad.bsky.social and Andrew Watrous!

New lab paper ! "Shared neural geometries for bilingual semantic representations in human hippocampal neurons" led by @xinyuanyan.bsky.social. 🧵 www.sciencedirect.com/science/arti...

How does the brain build a memory? A common assumption is that the neurons activated during an experience collectively form the memory engram. In our new Nature Neuroscience paper (finally out!), we show that this is not the case. www.nature.com/articles/s41...

Every time you experience something new, your brain faces a decision: Should it update an existing memory or create a new one? In our new paper in @sfnjournals.bsky.social #JNeurosci, we isolate that exact decision, moment-by-moment during learning 🧵

Today we present another of our amazing speakers: @anne-schreiter.bsky.social the executive director from @gso-forresearchers.bsky.social. She will give us an interactive workshop about Leadership and Team-building. Register to our @fens.org Satellite 👉 youngpisymposium2026.com

The deadline for our young PI symposium was extended! Don't miss out on this opportunity to build your community and share strategies to navigate these uncertain times.
