Deconstruction of a memory engram reveals distinct ensembles recruited at learning - Nature Neuroscience Pouget et al. identified distinct CA1 neuron ensembles active during specific moments of fear learning and uncovered the core engram essential for memory formation.

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.

It’s out! 🎉
My thesis research conducted in @funsycnrs.bsky.social team at @unistra.fr in collaboration with @cnrs.fr is published. Using new #EEG metrics, we show how #brain #dynamics are altered in early #Alzheimer’s & how 40 Hz visual #stimulation (vGENUS) can restore them and boost #memory. 🧠💡

New paper in Imaging Neuroscience by Matthieu Aguilera, Romain Goutagny et al.:

40 Hz light stimulation restores early brain dynamics alterations and associative memory in Alzheimer’s disease model mice

40 Hz light stimulation restores early brain dynamics alterations and associative memory in Alzheimer's disease model mice Abstract. Visual gamma entrainment using sensory stimuli (vGENUS) is a promising non-invasive therapeutic approach for Alzheimer's disease (AD), showing efficacy in improving memory function. However,...

🧠 New from FunSy!
Our latest in @imagingneurosci.bsky.social: @aguilera-matthieu.bsky.social shows that early brain dynamics disruptions and memory deficits in AD mice are rescued by 40 Hz visual stimulation (vGENUS)!

Experience reorganizes content-specific memory traces in macaques Memory formation requires neural activity reorganization during experience that persists in sleep. How these processes promote learning while preserving established memories remains unclear. We record...

How does the brain integrate information from new experiences while preserving established memories? Have a look at our latest preprint,

Etats-Unis : un chercheur français refoulé pour avoir exprimé « une opinion personnelle sur la politique menée par l’administration Trump » Le ministre de la recherche a dit sa « préoccupation », mercredi, après cette décision des autorités américaines. Le chercheur du CNRS aurait subi un contrôle aléatoire à son arrivée, avant que son or...

French researcher, going to a conference in Houston, was forbidden entry to US; his work and personal electronics were both confiscated.

Why? Because a “random search” of his cell phone revealed a negative personal opinion on Trump and the Trump administration. www.lemonde.fr/internationa...

Yet another fantastic study! Congrats Antonio and team!

⚠️ Un poste de MCU en Maths-Info-Stats s'ouvre bientôt à Sorbonne Université pour rejoindre mon équipe (background computationnel et experience en analyse de données de neurosciences experimentales souhaités + qualification requise). Contactez-moi pour plus d'infos!
