    Population codes enable learning from few examples by shaping inductive bias

    Blake Bordelon, Cengiz Pehlevan
    Neural sensory representations impose an inductive bias over the space of learning tasks, allowing some tasks to be learned by a downstream neuron more sample-efficiently than others.

    Distinct population code for movement kinematics and changes of ongoing movements in human subthalamic nucleus

    Dennis London, Arash Fazl ... Roozbeh Kiani
    Subthalamic nucleus spiking activity, beta oscillation power, and locking of spikes to the beta oscillation are decreased prior to changes in ongoing movements.

    Mixed-mode oscillations and population bursting in the pre-Bötzinger complex

    Bartholomew J Bacak, Taegyo Kim ... Ilya A Rybak
    Computational modeling reveals the mechanisms by which a diverse group of neurons in the brainstem generates rhythmic breathing in mammals.

    Synthesis of a comprehensive population code for contextual features in the awake sensory cortex

    Evan H Lyall, Daniel P Mossing ... Hillel Adesnik
    Novel stimulation patterns and large-scale neural activity recording show that an input-specific supra-linear summation synthesizes a sparse, but comprehensive code of tactile and visual stimuli in the sensory cortex.

    Visual and motor signatures of locomotion dynamically shape a population code for feature detection in Drosophila

    Maxwell H Turner, Avery Krieger ... Thomas R Clandinin
    Neurons responsible for detecting local visual features are modulated by visual and motor-related forms of gain control that increase the threshold for detection when self-generated movement signals would dominate visual input.

    Large-scale two-photon imaging revealed super-sparse population codes in the V1 superficial layer of awake monkeys

    Shiming Tang, Yimeng Zhang ... Tai Sing Lee
    Two-photon imaging reveals super-sparse responses to natural images in primate V1, which carry sufficient information for discrimination of the input natural images with high accuracy.

    A thesaurus for a neural population code

    Elad Ganmor, Ronen Segev, Elad Schneidman
    The activity patterns of populations of neurons in the retina are organized as semantic clusters (analogous to synonyms), in which component patterns bear little physical resemblance to one another but convey the same meaning.

    Stable task information from an unstable neural population

    Michael E Rule, Adrianna R Loback ... Timothy O'Leary
    Analysis and modelling of sensorimotor neural activity shows how ongoing plasticity and appropriately tuned weights can cope with substantial ongoing changes in the neural code.

    1. Epidemiology and Global Health

    Direct and indirect mortality impacts of the COVID-19 pandemic in the United States, March 1, 2020 to January 1, 2022

    Wha-Eum Lee, Sang Woo Park ... Cécile Viboud
    The overall mortality consequences of the COVID-19 pandemic in the United States are predominantly attributable to the direct impact of SARS-CoV-2 infection but there are substantial indirect effects among children and young adults, and in mortality from accidents, homicides, and overdoses.

    Dynamics and maintenance of categorical responses in primary auditory cortex during task engagement

    Rupesh K Chillale, Shihab Shamma ... Yves Boubenec
    Primary auditory cortex shows population-level correlates of sound categorization, with categorical patterns emerging during sound presentation and task engagement leading to asymmetrical representation of stimuli, indicating an early involvement in stimulus categorization.
