    Model discovery to link neural activity to behavioral tasks

    Jamie D Costabile, Kaarthik A Balakrishnan ... Martin Haesemeyer
    Model identification of neural encoding is an accessible system for the analysis of neural data that allows identifying and characterizing arbitrary relationships between neural activity and task-related variables such as behavior, stimuli, or internal states.

    Emergence of time persistence in a data-driven neural network model

    Sebastien Wolf, Guillaume Le Goc ... Rémi Monasson
    A data-driven model of the neural activity of a circuit essential to swimming orientation in zebrafish can be mathematically interpreted to unveil the dynamical mechanism leading to persistence in tail orientation.

    A dynamic neural resource model bridges sensory and working memory

    Ivan Tomić, Paul M Bays
    Psychophysical measurement and computational modeling show that sensory information cannot contribute directly to a cognitive judgment, but must first be integrated into resource-limited working memory.

    Visualization of currents in neural models with similar behavior and different conductance densities

    Leandro M Alonso, Eve Marder
    Visualization methods display the dynamics of the currents in conductance-based model neurons, and show how their contribution changes in response to perturbation.

    Internal models for interpreting neural population activity during sensorimotor control

    Matthew D Golub, Byron M Yu, Steven M Chase
    A novel analysis of neural activity recorded in monkeys performing a “brain-machine interface” task reveals that a mismatch between motor effectors and the brains’ internal models of those effectors can explain a substantial portion of movement errors.

    A neural network model of hippocampal contributions to category learning

    Jelena Sučević, Anna C Schapiro
    A neural network model of the hippocampus exhibits a division of labor across its two main pathways during category learning, with one pathway specializing in extracting systematic category information and another in encoding arbitrary details.

    16p11.2 microdeletion imparts transcriptional alterations in human iPSC-derived models of early neural development

    Julien G Roth, Kristin L Muench ... Theo D Palmer
    A model of in vitro human corticogenesis identifies alterations in gene expression caused by loss of 16p11.2 CNV genes in hiPSC-derived progenitor cells.

    Velocity coupling of grid cell modules enables stable embedding of a low dimensional variable in a high dimensional neural attractor

    Noga Mosheiff, Yoram Burak
    The neural representation of position in the medial entorhinal cortex may be stabilized by synaptic connectivity across modules, which enforces coherent updates in their states.
