Our paper on 'mini analysis' is now published in @jphysiol.bsky.social If you are recording mPSCs or sPSCs, I hope this helps with analysis. Interpretation of these datasets is not as easy as it seems..! Happy to discuss if you are interested physoc.onlinelibrary.wiley.com/doi/10.1113/...

‘Mini analysis’ misrepresents changes in synaptic properties due to incomplete event detection

Abstract figure legend Summary of the study where simulated recordings (left) were used to characterise the effect of incomplete detection on mini (mPSC) analysis. Recording noise levels (red) determ...

Our work looking into heterogeneous pyramidal neurons (PNs) in hippocampal CA3 is now online @cp-cellreports.bsky.social: www.sciencedirect.com/science/arti... With a pile of multicellular recordings from mouse CA3, we characterised the recurrent network at the single cell level...

Cell-specific wiring routes information flow through hippocampal CA3

The hippocampus, critical for learning and memory, is dogmatically described as a trisynaptic circuit where dentate gyrus granule cells (GCs), CA3 pyr…

A new paper from the group is online: we show that longterm low-frequency stimulation alleviates seizures beyond stimulation periods and reverses epilepsy-associated synaptic alterations. #TrEPILab www.sciencedirect.com/science/arti...

Long-term hippocampal low-frequency stimulation alleviates focal seizures, memory deficits and synaptic pathology in epileptic mice

Mesial temporal lobe epilepsy (MTLE) is a prevalent form of focal epilepsy characterized by seizures originating from the hippocampus and adjacent reg…

Incredibly impressive and powerful new method - connectomics with light microscopy! Congrats @mojtabart.bsky.social, Hans Danzl and team @istaresearch.bsky.social ! It works incredibly well - we will keep using this magic, and recommend you do too!

Light-microscopy-based connectomic reconstruction of mammalian brain tissue - Nature

A technique called LICONN (light-microscopy-based connectomics) allows mapping of brain tissue at synapse level and simultaneous measurement of molecular information, thus enabling quantification of c...

New preprint about SWRs, this time in HUMANS! 🤩 With @anna-maslarova.bsky.social and @JiyunShin, from @NYU, we’ve (i) developed a pipeline to analyze SWRs in intracranial EEG, and (ii) created ripmap, an open-source toolbox that allows versatile inspection and curation of events 🧵

Spatiotemporal Patterns Differentiate Hippocampal Sharp-Wave Ripples from Interictal Epileptiform Discharges in Mice and Humans

Hippocampal sharp-wave ripples (SPW-Rs) are high-frequency oscillations critical for memory consolidation in mammals. Despite extensive characterization in rodents, their application as biomarkers to ...

Stable maps from drifting neurons: CA1 solves the "representational drift paradox" through coordinated population dynamics. New preprint w/ @antjekilias.bsky.social , Marlene Bartos and @jf-sauer.bsky.social showing that representational drift isn’t random—it’s structured to preserve information🧵👇

Coordinated representational drift supports stable place coding in hippocampal CA1

The phenomenon of representational drift (i.e., changing neuronal tuning during repeated exposure to the same stimuli), is a fundamental paradox in neuroscience that raises the question how stable beh...

Are you interested in drifting place cells and the paradox of stable spatial maps? We have uploaded a new preprint: We find coordinated drifting in CA1. Very happy about this collaboration w/ @olechsylte.bsky.social, Marlene Bartos and @jf-sauer.bsky.social 👇👇👇

Our new preprint on long-term low-frequency stimulation in MTLE is online. We show that LFS has lasting effects on seizures even during stimulation-free periods and induces ultrastructural changes at the PP synapse.

Is neuroscience research really working to understand the human brain? Or do we get lost in mouse cognition? I’ve asked myself this a lot since starting to work with human tissue. Our first Jonas Lab foray into untangling human hippocampal circuits is now online! www.cell.com/cell/fulltex... 1/a few

Human hippocampal CA3 uses specific functional connectivity rules for efficient associative memory

Human hippocampal CA3 networks use sparse and broad synaptic connectivity, and their recurrent synapses employ reliability, precision, and long integration times to enhance memory capacity. Thus, the human hippocampus is distinct from both rodent counterparts and human neocortical circuits.
