    Pre-saccadic remapping relies on dynamics of spatial attention

    Martin Szinte, Donatas Jonikaitis ... Heiner Deubel
    To see the world stable across saccades, the brain compensates retinal shifts induced by the movements, pre-saccadic maps of sensitivity reveal that this process takes time and follows attentional dynamics.

    Mouse color and wavelength-specific luminance contrast sensitivity are non-uniform across visual space

    Daniel J Denman, Jennifer A Luviano ... R Clay Reid
    Mice can detect changes in hue independent of luminance, with differing sensitivity to hue and luminance in different parts of visual space.

    A principle of economy predicts the functional architecture of grid cells

    Xue-Xin Wei, Jason Prentice, Vijay Balasubramanian
    Mathematical modeling suggests that grid cells in the rodent brain use fundamental principles of number theory to maximize the efficiency of spatial mapping, enabling animals to accurately encode their location with as few neurons as possible.

    Calcium and bicarbonate signaling pathways have pivotal, resonating roles in matching ATP production to demand

    Maura Greiser, Mariusz Karbowski ... Liron Boyman
    A novel signaling system in heart mitochondria in which the byproduct of energy metabolism, CO2/bicarbonate, acts as the primary signal to tune mitochondrial ATP production while keeping energy supply in tight synchronization with energy consumption.
    1. Neuroscience

    Olfactory receptor neurons generate multiple response motifs, increasing coding space dimensionality

    Brian Kim, Seth Haney ... Mark A Stopfer
    The odor-elicited responses of olfactory receptor neurons consist of a discrete set of four spike pattern motifs, each with distinct adaptation properties, together amplifying distinctions between similar and temporally complex chemical inputs such as odor plumes.

    Space as a scaffold for rotational generalisation of abstract concepts

    Jacques Pesnot Lerousseau, Christopher Summerfield
    Spatial mapping serves as a cognitive scaffold for acquiring abstract conceptual invariances across sensory domains, shedding light on the mechanisms of human learning.

    Cell-sized confinement controls generation and stability of a protein wave for spatiotemporal regulation in cells

    Shunshi Kohyama, Natsuhiko Yoshinaga ... Nobuhide Doi
    A cell-sized fully confined space significantly controls the emergence and stability of a protein wave, resulting in intracellular spatiotemporal regulation driven by a reaction-diffusion mechanism.
    1. Neuroscience

    Short-term synaptic dynamics control the activity phase of neurons in an oscillatory network

    Diana Martinez, Haroon Anwar ... Farzan Nadim
    The phase of a neuron in an oscillatory network can remain independent of network frequency when synaptic input strength and peak phase are adjusted in a frequency-dependent manner.

    Emergent regulation of ant foraging frequency through a computationally inexpensive forager movement rule

    Lior Baltiansky, Guy Frankel, Ofer Feinerman
    Rather than complex decisions, it is the motion of individuals that allows for collective foraging regulation in ant colonies.
    1. Neuroscience

    Visual mode switching learned through repeated adaptation to color

    Yanjun Li, Katherine EM Tregillus ... Stephen A Engel
    The visual system can learn to rapidly adjust itself through experience, switching modes to stabilize vision perception and optimize perceptual processes.
