Whether CA3–CA3 recurrent connectivity is genetically preconfigured or environmentally shaped during ongoing memory storage is currently unknown. To address this question, we performed multicellular patch-clamp-based circuit mapping of up to eight CA3 PNs in the mouse hippocampus at multiple postnatal time points (P7–8, P18–25, and P45–50). Here, we show that the hippocampal CA3 network undergoes a developmental transformation from local, dense, and random connectivity to a distributed, sparse, and structured configuration. Thus, sparse and structured connectivity may emerge via experience-dependent mechanisms. In parallel, the strength of single synapses is downregulated; single synaptic events are sufficient to trigger postsynaptic spiking early in development, whereas spatial summation of several inputs is required at later time points. Biologically inspired models of memory storage by Hebbian synaptic plasticity and retrieval via pattern completion suggest that developmental changes improve specific aspects of memory storage and retrieval. Our results imply a developmental transformation of the neuronal code and the memory functions in the hippocampal CA3 network.</jats:p>","lang":"eng"}],"ec_funded":1,"pmid":1,"oa_version":"Published Version","volume":17,"date_published":"2026-06-23T00:00:00Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2026","title":"Developmental emergence of sparse and structured synaptic connectivity in the hippocampal CA3 memory circuit","article_processing_charge":"Yes","author":[{"id":"2F55A9DE-F248-11E8-B48F-1D18A9856A87","full_name":"Vargas Barroso, Victor M","first_name":"Victor M","last_name":"Vargas Barroso"},{"orcid":"0000-0002-8698-3823","id":"63836096-4690-11EA-BD4E-32803DDC885E","last_name":"Watson","full_name":"Watson, Jake","first_name":"Jake"},{"full_name":"Navas Olivé, Andrea C","first_name":"Andrea C","last_name":"Navas Olivé","id":"739d26c9-52e8-11ee-8d72-f14d3893b4ce","orcid":"0000-0002-9280-8597"},{"last_name":"Schlögl","full_name":"Schlögl, Alois","first_name":"Alois","orcid":"0000-0002-5621-8100","id":"45BF87EE-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Jonas","full_name":"Jonas, Peter M","first_name":"Peter M","orcid":"0000-0001-5001-4804","id":"353C1B58-F248-11E8-B48F-1D18A9856A87"}],"acknowledgement":"We thank Jose Guzman, Simon Hippenmeyer, and Tim Vogels for critically reading the manuscript, Jozsef Csicsvari for useful discussions, Florian Marr for technical assistance, and Eleftheria Kralli-Beller for manuscript editing.

However, little of our neuroscience knowledge covers the human brain. Is this organ truly unique, or is it a scaled version of the extensively studied rodent brain? Combining multicellular patch-clamp recording with expansion-based superresolution microscopy and full-scale modeling, we determined the cellular and microcircuit properties of the human hippocampal CA3 region, a fundamental circuit for memory storage. In contrast to neocortical networks, human hippocampal CA3 displayed sparse connectivity, providing a circuit architecture that maximizes associational power. Human synapses showed unique reliability, high precision, and long integration times, exhibiting both species- and circuit-specific properties. Together with expanded neuronal numbers, these circuit characteristics greatly enhanced the memory storage capacity of CA3. Our results reveal distinct microcircuit properties of the human hippocampus and begin to unravel the inner workings of our most complex organ.

With this approach, spontaneous synaptic transmission events are recorded in an attempt to determine quantal synaptic parameters or the effect of synaptic manipulations. However, at the majority of brain synapses these events are small, with many undetectable due to recording noise. The effects of incomplete detection were well appreciated in the early years of synaptic physiology analysis, but appear to be increasingly forgotten. Here we sought to characterise the consequences of incomplete detection on the interpretability of mini analysis, using simulated mPSC data to give full control over event parameters. We demonstrate that commonly reported measures such as mean event amplitude and frequency, are misrepresented by the loss of undetected events. Probabilistic loss of small events results in detected event amplitude distributions that appear biologically complete, yet do not reflect the underlying synaptic properties. With both simulated and experimental datasets, we demonstrate that specific changes in event amplitude are primarily detected as changes in frequency, compromising classical biological interpretations. To facilitate more robust data analysis and interpretation, we detail a means for experimental estimation of the event detection limit and provide practical recommendations for data analysis. Together, our study highlights how mini analysis is prone to falsely reporting synaptic changes, raising awareness of these considerations, and provides a framework for more robust data analysis and interpretation.","lang":"eng"}],"ec_funded":1,"scopus_import":"1","OA_type":"hybrid","_id":"20457","issue":"22","date_updated":"2026-01-05T13:13:32Z","citation":{"ieee":"I.

Here we developed Comprehensive Analysis of Tissues across Scales (CATS), a technology to densely map brain tissue architecture from millimeter regional to nanometer synaptic scales in diverse chemically fixed brain preparations, including rodent and human. CATS uses fixation-compatible extracellular labeling and optical imaging, including stimulated emission depletion or expansion microscopy, to comprehensively delineate cellular structures. It enables three-dimensional reconstruction of single synapses and mapping of synaptic connectivity by identification and analysis of putative synaptic cleft regions. Applying CATS to the mouse hippocampal mossy fiber circuitry, we reconstructed and quantified the synaptic input and output structure of identified neurons. We furthermore demonstrate applicability to clinically derived human tissue samples, including formalin-fixed paraffin-embedded routine diagnostic specimens, for visualizing the cellular architecture of brain tissue in health and disease."}],"language":[{"iso":"eng"}],"oa":1,"file_date_updated":"2025-01-09T07:48:01Z","OA_type":"hybrid","scopus_import":"1","_id":"14257","related_material":{"record":[{"id":"18660","relation":"dissertation_contains","status":"deleted"},{"status":"public","relation":"research_data","id":"13126"},{"id":"18674","relation":"dissertation_contains","status":"public"}],"link":[{"url":"https://github.com/danzllab/CATS","relation":"software"}]},"quality_controlled":"1","citation":{"ista":"Michalska JM, Lyudchik J, Velicky P, Korinkova H, Watson J, Cenameri A, Sommer CM, Amberg N, Venturino A, Roessler K, Czech T, Höftberger R, Siegert S, Novarino G, Jonas PM, Danzl JG. 2024.

A combination of AMPAR structural data, super-resolution imaging of excitatory synapses, and an abundance of electrophysiological studies are providing an ever-clearer picture of how AMPARs are recruited and organized at synaptic junctions. Here, we review the latest insights into this process, and discuss how both cytoplasmic and extracellular receptor elements cooperate to tune the AMPAR response at the hippocampal CA1 synapse.","lang":"eng"}],"scopus_import":"1","OA_type":"hybrid"},{"author":[{"id":"63836096-4690-11EA-BD4E-32803DDC885E","orcid":"0000-0002-8698-3823","first_name":"Jake","full_name":"Watson, Jake","last_name":"Watson"},{"full_name":"Arroyo-Urea, Sandra","first_name":"Sandra","last_name":"Arroyo-Urea"},{"last_name":"García-Nafría","full_name":"García-Nafría, Javier","first_name":"Javier"}],"type":"book_chapter","date_created":"2024-09-11T10:40:36Z","publication_status":"published","department":[{"_id":"PeJo"}],"doi":"10.1201/9781003055211-8","date_published":"2024-09-05T00:00:00Z","oa_version":"None","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","page":"66-72","year":"2024","title":"DNA Cloning","article_processing_charge":"No","editor":[{"first_name":"Dongyou","full_name":"Liu, Dongyou","last_name":"Liu"}],"day":"05","status":"public","scopus_import":"1","language":[{"iso":"eng"}],"publication":"Handbook of Molecular Biotechnology","abstract":[{"text":"DNA cloning is a core technique in biomedical and biotechnological research and is used to assemble and modify DNA fragments at will.

This pathway is present in all standard laboratory E. coli strains and, by bypassing the need for in vitro DNA assembly, allows simplified molecular cloning to be performed without the plasmid instability issues associated with specialized recombination-cloning bacterial strains. The methodology requires specific primer design and can perform all standard plasmid modifications (insertions, deletions, mutagenesis, and sub-cloning) in a rapid, simple, and cost-efficient manner, as it does not require commercial kits or specialized bacterial strains. Additionally, this approach can be used to perform complex procedures such as multiple modifications to a plasmid, as up to 6 linear fragments can be assembled in vivo by this recombination pathway. Procedures generally require less than 3 h, involving PCR amplification, DpnI digestion of template DNA, and transformation, upon which circular plasmids are assembled. In this chapter we describe the requirements, procedure, and potential pitfalls when using this technique, as well as protocol variations to overcome the most common issues.","lang":"eng"}],"scopus_import":"1","OA_type":"green","place":"New York, NY, United States","_id":"12720","alternative_title":["Methods in Molecular Biology"],"date_updated":"2025-06-25T05:56:45Z","citation":{"ieee":"S.

Their signalling is uniquely diversified by brain region-specific auxiliary subunits, providing an opportunity for the development of selective therapeutics. AMPARs associated with TARP γ8 are enriched in the hippocampus, and are targets of emerging anti-epileptic drugs. To understand their therapeutic activity, we determined cryo-EM structures of the GluA1/2-γ8 receptor associated with three potent, chemically diverse ligands. We find that despite sharing a lipid-exposed and water-accessible binding pocket, drug action is differentially affected by binding-site mutants. Together with patch-clamp recordings and MD simulations we also demonstrate that ligand-triggered reorganisation of the AMPAR-TARP interface contributes to modulation. Unexpectedly, one ligand (JNJ-61432059) acts bifunctionally, negatively affecting GluA1 but exerting positive modulatory action on GluA2-containing AMPARs, in a TARP stoichiometry-dependent manner. These results further illuminate the action of TARPs, demonstrate the sensitive balance between positive and negative modulatory action, and provide a mechanistic platform for development of both positive and negative selective AMPAR modulators.","lang":"eng"}],"file_date_updated":"2023-04-03T06:38:56Z","oa":1,"language":[{"iso":"eng"}],"scopus_import":"1","article_processing_charge":"No","title":"Modulatory mechanisms of TARP γ8-selective AMPA receptor therapeutics","year":"2023","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"Published Version","volume":14,"date_published":"2023-03-25T00:00:00Z","article_number":"1659","ddc":["570"],"external_id":{"isi":["001066658700003"]},"acknowledgement":"We thank James Krieger for generating the ‘proDy’ interaction maps in Fig. 5B and S7C, and Jan-Niklas Dohrke for critically reading the manuscript.

Super-resolution optical microscopy excels at visualizing specific molecules and individual cells but fails to provide tissue context. Here we developed Comprehensive Analysis of Tissues across Scales (CATS), a technology to densely map brain tissue architecture from millimeter regional to nanoscopic synaptic scales in diverse chemically fixed brain preparations, including rodent and human. CATS leverages fixation-compatible extracellular labeling and advanced optical readout, in particular stimulated-emission depletion and expansion microscopy, to comprehensively delineate cellular structures. It enables 3D-reconstructing single synapses and mapping synaptic connectivity by identification and tailored analysis of putative synaptic cleft regions. Applying CATS to the hippocampal mossy fiber circuitry, we demonstrate its power to reveal the system’s molecularly informed ultrastructure across spatial scales and assess local connectivity by reconstructing and quantifying the synaptic input and output structure of identified neurons.","lang":"eng"}],"status":"public","corr_author":"1","article_processing_charge":"No","day":"18","title":"Uncovering brain tissue architecture across scales with super-resolution light microscopy","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2022","oa_version":"Preprint","date_published":"2022-08-18T00:00:00Z","doi":"10.1101/2022.08.17.504272","department":[{"_id":"SaSi"},{"_id":"GaNo"},{"_id":"PeJo"},{"_id":"JoDa"}],"author":[{"last_name":"Michalska","full_name":"Michalska, Julia M","first_name":"Julia M","orcid":"0000-0003-3862-1235","id":"443DB6DE-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Lyudchik, Julia","first_name":"Julia","last_name":"Lyudchik","id":"46E28B80-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Velicky, Philipp","first_name":"Philipp","last_name":"Velicky","id":"39BDC62C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2340-7431"},{"first_name":"Hana","full_name":"Korinkova, Hana","last_name":"Korinkova","id":"ee3cb6ca-ec98-11ea-ae11-ff703e2254ed"},{"orcid":"0000-0002-8698-3823","id":"63836096-4690-11EA-BD4E-32803DDC885E","last_name":"Watson","first_name":"Jake","full_name":"Watson, Jake"},{"last_name":"Cenameri","first_name":"Alban","full_name":"Cenameri, Alban","id":"9ac8f577-2357-11eb-997a-e566c5550886"},{"last_name":"Sommer","full_name":"Sommer, Christoph M","first_name":"Christoph M","orcid":"0000-0003-1216-9105","id":"4DF26D8C-F248-11E8-B48F-1D18A9856A87"},{"orcid":"0000-0003-2356-9403","id":"41CB84B2-F248-11E8-B48F-1D18A9856A87","last_name":"Venturino","first_name":"Alessandro","full_name":"Venturino, Alessandro"},{"last_name":"Roessler","first_name":"Karl","full_name":"Roessler, Karl"},{"last_name":"Czech","first_name":"Thomas","full_name":"Czech, Thomas"},{"full_name":"Siegert, Sandra","first_name":"Sandra","last_name":"Siegert","id":"36ACD32E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8635-0877"},{"first_name":"Gaia","full_name":"Novarino, Gaia","last_name":"Novarino","id":"3E57A680-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-7673-7178"},{"last_name":"Jonas","full_name":"Jonas, Peter M","first_name":"Peter M","orcid":"0000-0001-5001-4804","id":"353C1B58-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Danzl","full_name":"Danzl, Johann G","first_name":"Johann G","orcid":"0000-0001-8559-3973","id":"42EFD3B6-F248-11E8-B48F-1D18A9856A87"}],"type":"preprint","date_created":"2022-08-24T08:24:52Z","publication_status":"draft"},{"abstract":[{"lang":"eng","text":"AMPA receptors (AMPARs) mediate the majority of excitatory transmission in the brain and enable the synaptic plasticity that underlies learning1. A diverse array of AMPAR signalling complexes are established by receptor auxiliary subunits, which associate with the AMPAR in various combinations to modulate trafficking, gating and synaptic strength2. However, their mechanisms of action are poorly understood. Here we determine cryo-electron microscopy structures of the heteromeric GluA1–GluA2 receptor assembled with both TARP-γ8 and CNIH2, the predominant AMPAR complex in the forebrain, in both resting and active states. Two TARP-γ8 and two CNIH2 subunits insert at distinct sites beneath the ligand-binding domains of the receptor, with site-specific lipids shaping each interaction and affecting the gating regulation of the AMPARs. Activation of the receptor leads to asymmetry between GluA1 and GluA2 along the ion conduction path and an outward expansion of the channel triggers counter-rotations of both auxiliary subunit pairs, promoting the active-state conformation. In addition, both TARP-γ8 and CNIH2 pivot towards the pore exit upon activation, extending their reach for cytoplasmic receptor elements. CNIH2 achieves this through its uniquely extended M2 helix, which has transformed this endoplasmic reticulum-export factor into a powerful AMPAR modulator that is capable of providing hippocampal pyramidal neurons with their integrative synaptic properties.

Changes in AMPAR localisation can enact synaptic plasticity, allowing long-term information storage, and is therefore tightly controlled. Multiple mechanisms regulating AMPAR synaptic anchoring have been described, but with limited coherence or comparison between reports, our understanding of this process is unclear. Here, combining synaptic recordings from mouse hippocampal slices and super-resolution imaging in dissociated cultures, we compare the contributions of three AMPAR interaction domains controlling transmission at hippocampal CA1 synapses. We show that the AMPAR C-termini play only a modulatory role, whereas the extracellular N-terminal domain (NTD) and PDZ interactions of the auxiliary subunit TARP γ8 are both crucial, and each is sufficient to maintain transmission. Our data support a model in which γ8 accumulates AMPARs at the postsynaptic density, where the NTD further tunes their positioning. This interplay between cytosolic (TARP γ8) and synaptic cleft (NTD) interactions provides versatility to regulate synaptic transmission and plasticity."}],"scopus_import":"1","_id":"9985","issue":"1","citation":{"mla":"Watson, Jake, et al. “AMPA Receptor Anchoring at CA1 Synapses Is Determined by N-Terminal Domain and TARP Γ8 Interactions.” <i>Nature Communications</i>, vol. 12, no. 1, 5083, Nature Publishing Group, 2021, doi:<a href=\"https://doi.org/10.1038/s41467-021-25281-4\">10.1038/s41467-021-25281-4</a>.","ieee":"J.
