    Coding of latent variables in sensory, parietal, and frontal cortices during closed-loop virtual navigation

    Jean-Paul Noel, Edoardo Balzani ... Dora E Angelaki
    Primates use their eyes to keep track of spatial goals, and this strategy is reflected by the functional connectivity between a traditionally considered optic flow area (dorsomedial superior temporal area) and prefrontal cortex.

    Neural criticality from effective latent variables

    Mia C Morrell, Ilya Nemenman, Audrey Sederberg
    Signatures of criticality that have been observed across diverse neural systems, such as power-law avalanche distributions and exponent relationships, can arise without fine-tuning in networks coupled to latent, dynamical variables.

    Sex differences in learning from exploration

    Cathy S Chen, Evan Knep ... Nicola M Grissom
    A new computational analysis of decision making in mice shows sex biases in value-updating while exploring unknown options, with male mice tending to explore longer than females due to updating values more slowly.

    Gated recurrence enables simple and accurate sequence prediction in stochastic, changing, and structured environments

    Cédric Foucault, Florent Meyniel
    Small gated recurrent neural networks can dynamically adapt to inferred changes in the environment, represent and use the precision of their estimate to weight their updates, and leverage the environment's latent hierarchical structure, like the Bayesian agent and the brain.

    Toward a more informative representation of the fetal–neonatal brain connectome using variational autoencoder

    Jung-Hoon Kim, Josepheen De Asis-Cruz ... Catherine Limperopoulos
    A nonlinear deep generative model can represent fetal–neonatal resting-state functional magnetic resonance imaging better than conventional linear models.

    Modelling the neural code in large populations of correlated neurons

    Sacha Sokoloski, Amir Aschner, Ruben Coen-Cagli
    The proposed techniques enable researchers to disentangle the statistical features of neural population responses, and rigorously quantify how these features carry information about stimuli and experimental variables.

    Local field potentials reflect cortical population dynamics in a region-specific and frequency-dependent manner

    Cecilia Gallego-Carracedo, Matthew G Perich ... Juan Álvaro Gallego
    There is a frequency-dependent association between the local field potential and the coordinated activity of populations of single neurons, which remains constant during different aspects of behaviour but changes across regions of primate sensorimotor cortex.

    Adaptive coding for dynamic sensory inference

    Wiktor F Młynarski, Ann M Hermundstad
    To make reliable but metabolically efficient perceptual inferences in a changing world, neural systems should dynamically adapt based on surprise and uncertainty about the sensory environment.

    Low-dimensional learned feature spaces quantify individual and group differences in vocal repertoires

    Jack Goffinet, Samuel Brudner ... John Pearson
    Modern machine learning methods offer new techniques for analyzing complex vocal behavior like ultrasonic mouse calls and birdsong.

    Hidden long-range memories of growth and cycle speed correlate cell cycles in lineage trees

    Erika E Kuchen, Nils B Becker ... Thomas Höfer
    The combination of statistical inference and perturbation experiments reveals that trans-generational inheritance of cell size and cell-cycle speed, coupled through a minimum-size checkpoint, shapes paradoxical cell-cycle correlations in lineage trees.
