    Beta band oscillations in motor cortex reflect neural population signals that delay movement onset

    Preeya Khanna, Jose M Carmena
    Using a sequential neurofeedback-arm reaching task, a new link is established among population neural activity patterns, generation of beta oscillations, and motor behavior changes.

    Demixed principal component analysis of neural population data

    Dmitry Kobak et al.
    A new data analysis tool provides a concise way of visualizing neural data that summarizes all the relevant features of the population response in a single figure.

    Mouse V1 population correlates of visual detection rely on heterogeneity within neuronal response patterns

    Jorrit S Montijn et al.
    Heterogeneity of neural responses in mouse cortex correlates better with visual detection than mean population activity.

    The modulation of neural gain facilitates a transition between functional segregation and integration in the brain

    James M Shine et al.
    The flexible network architecture of the brain is sensitive to the modulation of neural gain, which may be mediated by ascending arousal nuclei, such as the noradrenergic locus coeruleus.

    Antagonistic modulation of NPY/AgRP and POMC neurons in the arcuate nucleus by noradrenalin

    Lars Paeger et al.
    The coordinated differential modulation of satiety signaling POMC- and hunger signaling AgRP- neurons in the arcuate nucleus of the hypothalamus assigns an important role to noradrenalin to promote feeding.

    A thesaurus for a neural population code

    Elad Ganmor et al.
    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.

    Population response magnitude variation in inferotemporal cortex predicts image memorability

    Andrew Jaegle et al.
    Population response magnitude predicts how well an image will be remembered, in both monkey inferotemporal cortex and neural networks trained to categorize objects.

    Paradoxical response reversal of top-down modulation in cortical circuits with three interneuron types

    Luis Carlos Garcia del Molino et al.
    Computational simulations and mathematical derivations reveal why the response of neural populations to external modulation is sometimes reversed with respect to what intuition would lead to believe in cortical circuits with multiple types of inhibitory neurons.

    Inhibitory peptidergic modulation of C. elegans serotonin neurons is gated by T-type calcium channels

    Kara E Zang et al.
    Genetic analysis of how neuropeptides control C. elegans reproductive behavior shows how T-type calcium channels engage and disengage target neurons from these critical regulators of neural circuits and behavior.
