    Precise excitation-inhibition balance controls gain and timing in the hippocampus

    Aanchal Bhatia, Sahil Moza, Upinder Singh Bhalla
    Delayed inhibition precisely balances excitation from arbitrary combinations of CA3 neurons and controls the gain of CA1 output by reducing inhibitory delay with increasing excitation.

    Signaling pathways as linear transmitters

    Harry Nunns, Lea Goentoro
    Mathematical and experimental analyses suggest that despite their complex architectures, multiple metazoan signaling pathways act in physiological contexts as linear signal transmitters.

    Coding of chromatic spatial contrast by macaque V1 neurons

    Abhishek De, Gregory D Horwitz
    Many V1 double-opponent cells integrate light information across their receptive fields as linearly as simple cells do.

    The cerebellum linearly encodes whisker position during voluntary movement

    Susu Chen, George J Augustine, Paul Chadderton
    Cerebellar Purkinje cells represent movements via bidirectional linear changes in spike rate, and activity from single cells is sufficient to reconstruct kinematic changes during bouts of free whisking.

    State-dependent representations of mixtures by the olfactory bulb

    Aliya Mari Adefuin, Sander Lindeman ... Izumi Fukunaga
    Responses to odour mixtures are more discriminable in awake, behaving mice due to a combination of dampened responses keeping responses in the linear range and pattern decorrelation, with these two mechanisms operating on different timescales.

    Adaptation in cone photoreceptors contributes to an unexpected insensitivity of primate On parasol retinal ganglion cells to spatial structure in natural images

    Zhou Yu, Maxwell H Turner ... Fred Rieke
    A combination of electrophysiology and quantitative modeling shows that subtle changes in input due to adaptation in cone phototransduction control the linearity or nonlinearity of how ganglion cells integrate spatial inputs.

    Signaling Systems: Transferring information without distortion

    Steven S Andrews, Roger Brent, Gábor Balázsi
    Despite employing diverse molecular mechanisms, many different cell signaling systems avoid losing information by transmitting it in a linear manner.

    Condensin DC loads and spreads from recruitment sites to create loop-anchored TADs in C. elegans

    Jun Kim, David S Jimenez ... Sevinc Ercan
    Loading and linear translocation of condensin dosage compensation along the X-chromosomes create the loop-anchored topologically associating domains detected by Hi-C.

    Mapping nonlinear receptive field structure in primate retina at single cone resolution

    Jeremy Freeman, Greg D Field ... EJ Chichilnisky
    Multi-electrode recordings and modeling are combined to reveal the transformations of signals from cones to bipolar cells and then to ganglion cells within the primate retina.

    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.
