    Biophysical clocks face a trade-off between internal and external noise resistance

    Weerapat Pittayakanchit et al.
    Molecular clocks that are robust to external fluctuations are vulnerable to internal fluctuations and vice versa.

    Contribution of correlated noise and selective decoding to choice probability measurements in extrastriate visual cortex

    Yong Gu et al.
    Addressing the controversy regarding the interpretation of choice probabilities demonstrates that both readout strategy and noise correlations contribute to the link between neural activity and perceptual decisions.

    Cross-synaptic synchrony and transmission of signal and noise across the mouse retina

    William N Grimes et al.
    Cells within the retina synchronize transmitter release across their output synapses in the dark, reducing the impact of noise generated at these synapses and allowing light-dependent signals to be transmitted with minimal added synaptic noise.

    Attentional modulation of neuronal variability in circuit models of cortex

    Tatjana Kanashiro et al.
    Attention reduces noise correlations through enhancing inhibitory feedback in cortical networks.

    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).

    Efficient sampling and noisy decisions

    Joseph A Heng et al.
    An efficient coding theory for higher-level cognitive processes reveals that humans efficiently adapt to contextual distributions by economizing on environmental prior information.

    Persistence, period and precision of autonomous cellular oscillators from the zebrafish segmentation clock

    Alexis B Webb et al.
    Time-lapse recording and theoretical analysis of individual cells isolated from the zebrafish segmentation clock reveal that they behave as self-sustained, autonomous oscillators with distinctive noisy dynamics.

    Phenotypic diversity and temporal variability in a bacterial signaling network revealed by single-cell FRET

    Johannes M Keegstra et al.
    Noise in a signaling network comprising thousands of molecules shapes diversity across cell populations and generates giant temporal fluctuations at the single-cell level.

    Massive normalization of olfactory bulb output in mice with a 'monoclonal nose'

    Benjamin Roland et al.
    Inhibitory circuits in the olfactory bulb can amplify or suppress sensory inputs over a wide range of intensities to generate robust mitral cell output.

    Sources of noise during accumulation of evidence in unrestrained and voluntarily head-restrained rats

    Benjamin B Scott et al.
    Statistical analysis of evidence-based decisions reveals new insights into the source of behavioral variability.
