    A neural-level model of spatial memory and imagery

    Andrej Bicanski, Neil Burgess
    The BB model explains spatial cognition in terms of interactions between specific neuronal populations, providing a common computational framework for the human neuropsychological and in vivo animal electrophysiological literatures.

    Framing of grid cells within and beyond navigation boundaries

    Francesco Savelli et al.
    Grid-cell maps can be aligned to both local and remote reference frames, suggesting that they provide a metric for space beyond the navigationally accessible boundaries of the local environment.
    1. Neuroscience

    A principle of economy predicts the functional architecture of grid cells

    Xue-Xin Wei et al.
    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.

    Dynamic representation of partially occluded objects in primate prefrontal and visual cortex

    Amber M Fyall et al.
    Complementary neural codes in frontal and visual cortex support a role for feedback signals in the representation and recognition of partially occluded objects.

    How spatial release from masking may fail to function in a highly directional auditory system

    Norman Lee, Andrew C Mason
    The auditory periphery of Ormia ochracea does not allow for spatial release from masking.

    Grid-cell representations in mental simulation

    Jacob LS Bellmund et al.
    Functional magnetic resonance imaging performed while people imagined directions from stationary viewpoints supports theories suggesting that spatially tuned cells such as grid cells underlie mental simulation for future thinking.

    Noise promotes independent control of gamma oscillations and grid firing within recurrent attractor networks

    Lukas Solanka et al.
    Random fluctuations in neuronal firing may enable a single brain region, the medial entorhinal cortex, to perform distinct roles in cognition (by generating gamma waves) and spatial navigation (by producing a grid cell map).

    Rat anterior cingulate cortex recalls features of remote reward locations after disfavoured reinforcements

    Ali Mashhoori et al.
    The anterior cingulate cortex intermixes a precise spatial map with a cognitive map of the task, and spontaneously recalls multimodal information about unrealized choice outcomes during pauses in behavior after reinforcements.
  1. Meta-Research: How significant are the public dimensions of faculty work in review, promotion and tenure documents?

    Juan P Alperin et al.
    An analysis of review, promotion and tenure documents from 129 US and Canadian universities suggests institutions could better fulfill their public missions by changing how they incentivize the public dimensions of faculty work.
