    Likelihood approximation networks (LANs) for fast inference of simulation models in cognitive neuroscience

    Alexander Fengler, Lakshmi N Govindarajan ... Michael J Frank
    A novel method and software provides researchers with the capability to rapidly, flexibly, and robustly perform Bayesian parameter estimation of theoretically meaningful models in cognitive neuroscience that were heretofore intractable.

    Self-organization of in vitro neuronal assemblies drives to complex network topology

    Priscila C Antonello, Thomas F Varley ... Jean Faber
    Effectively connected neurons self-organize forming networks with a small-world architecture composed of modules, with most likely few and nearby neurons, integrated by more topologically important and high firing rate neurons.

    Unsupervised discovery of temporal sequences in high-dimensional datasets, with applications to neuroscience

    Emily L Mackevicius, Andrew H Bahle ... Michale S Fee
    Building on simple unsupervised matrix factorization techniques, the seqNMF algorithm successfully recovers neural sequences in a wide range of simulated and real datasets.

    Cell assemblies at multiple time scales with arbitrary lag constellations

    Eleonora Russo, Daniel Durstewitz
    A novel statistical algorithm for mining high-dimensional spike train (count) data for significant spatio-temporal patterns reveals new insights into task and brain area dependent functional organization of neural activity.
    1. Neuroscience

    Neuronal sequences during theta rely on behavior-dependent spatial maps

    Eloy Parra-Barrero, Kamran Diba, Sen Cheng
    A computational framework and analysis of rodent CA1 data reveals that theta oscillations sequentially sweep through the past, present, and future at a spatial scale that varies with the characteristic speed of the animal.

    Real-time classification of experience-related ensemble spiking patterns for closed-loop applications

    Davide Ciliberti, Frédéric Michon, Fabian Kloosterman
    A brain–computer interface for real-time identification of transient neural activity patterns enables causal inference of the role of these patterns in cognition through closed-loop manipulation.

    Pynapple, a toolbox for data analysis in neuroscience

    Guillaume Viejo, Daniel Levenstein ... Adrien Peyrache
    Pynapple advances data analysis in systems neuroscience with a versatile, open-source framework that uses common objects to handle diverse data streams, ensuring reliable and reproducible analysis while maintaining long-term backward compatibility.

    Multivariate cross-frequency coupling via generalized eigendecomposition

    Michael X Cohen
    A novel methodological framework for cross-frequency coupling and spike-field coherence in multichannel (LFP, EEG, MEG) electrophysiology data reveals new manifestations of coupling dynamics.

    Fast and flexible sequence induction in spiking neural networks via rapid excitability changes

    Rich Pang, Adrienne L Fairhall
    Biologically plausible changes in the excitabilities of single neurons may suffice to selectively modulate sequential network dynamics, without modifying of recurrent connectivity.
    1. Neuroscience

    A spiral attractor network drives rhythmic locomotion

    Angela M Bruno, William N Frost, Mark D Humphries
    The neural population of the Aplysia's pedal ganglion are a low-dimensional spiral attractor, and the parameters of the attractor directly define the properties of the Aplysia's escape locomotion behaviour.
