    Thalamic reticular nucleus induces fast and local modulation of arousal state

    Laura D Lewis et al.
    A neural circuit that can selectively induce sleep-like patterns in small regions of the brain demonstrates how sleep and arousal states may be controlled in local brain regions.

    Neurocalcin regulates nighttime sleep and arousal in Drosophila

    Ko-Fan Chen et al.
    The neuronal calcium sensor Neurocalcin regulates sleep and arousal thresholds during the night in Drosophila.

    Differential regulation of the Drosophila sleep homeostat by circadian and arousal inputs

    Jinfei D Ni et al.
    Functional imaging and circuit mapping in the Drosophila brain identifies neuropils where sleep-promoting and arousal-promoting neuronal networks converge.

    Behavioural and neural signatures of perceptual decision-making are modulated by pupil-linked arousal

    Jochem van Kempen et al.
    A direct relationship between pupil diameter and electrophysiological correlates of attention, sensory stimulus processing and target detection was observed demonstrating that arousal has a substantial influence on perceptual decision-making.

    Unexpected arousal modulates the influence of sensory noise on confidence

    Micah Allen et al.
    Changes in physiological arousal – as revealed by pupil dilation and heart rate – shape our confidence in decisions about uncertain perceptual information.

    A highly tunable dopaminergic oscillator generates ultradian rhythms of behavioral arousal

    Ian D Blum et al.
    An internal clock based on brain levels of dopamine works with the circadian clock to maintain daily patterns of alertness and activity, and may be implicated in the altered behavioral patterns seen in schizophrenia and bipolar disorder.

    Regulation of sleep homeostasis by sexual arousal

    Esteban J Beckwith et al.
    Sexual arousal, exposure to aphrodisiac pheromones, or mere activation of peripheral pheromone-sensing neurons can modulate sleep homeostasis and are able to counteract the effects of sleep deprivation in Drosophila.

    Dynamic modulation of decision biases by brainstem arousal systems

    Jan Willem de Gee et al.
    Rapid increases in the brain’s level of alertness, or arousal, contribute to variability in decision making by reducing existing biases.
    1. Neuroscience

    Frequency-selective control of cortical and subcortical networks by central thalamus

    Jia Liu et al.
    Central thalamus relay neurons dynamically switch the activity of cortical and subcortical networks at distinct frequencies, providing a mechanism for this region's role in arousal regulation.
    1. Neuroscience

    Norepinephrine is required to promote wakefulness and for hypocretin-induced arousal in zebrafish

    Chanpreet Singh et al.
    Experiments in genetically modified zebrafish that are unable to produce norepinephrine show that this neurotransmitter promotes wakefulness by mediating the effects of the neuropeptide hypocretin.
