    Differential temporal dynamics during visual imagery and perception

    Nadine Dijkstra, Pim Mostert ... Marcel AJ van Gerven
    In contrast to perception, during visual imagery, there are no clear time-locked processing stages and imagery specifically overlaps with perceptual processing around 160 ms after stimulus onset and from 300 ms onwards.

    Altered functional connectivity during speech perception in congenital amusia

    Kyle Jasmin, Frederic Dick ... Adam Taylor Tierney
    Individuals with amusia, who have unreliable pitch processing, show decreased functional connectivity between right auditory and left language-related cortex during speech perception, demonstrating a neural basis for compensatory dimensional weighting.

    Separable pupillary signatures of perception and action during perceptual multistability

    Jan W Brascamp, Gilles de Hollander ... Tomas Knapen
    When conscious visual perception changes, the observer's pupils simultaneously signal the accompanying change in visual cortical representation, and specific neuromodulatory activity that helps translate the altered visual experience into behavior.

    Theta oscillations locked to intended actions rhythmically modulate perception

    Alice Tomassini, Luca Ambrogioni ... Eric Maris
    Theta oscillations synchronize perception with the emerging motor intention in an automatic and task-independent way.

    Slowing the body slows down time perception

    Rose De Kock, Weiwei Zhou ... Martin Wiener
    The perception of time is influenced by movement environments, with slower movements associated with shorter perceived time intervals.

    Feedback contribution to surface motion perception in the human early visual cortex

    Ingo Marquardt, Peter De Weerd ... Kâmil Uludağ
    Novel evidence for a role of feedback in the perception of uniform surfaces in the human brain suggests that feedback already re-enters at an early visual processing stage.

    Neuronal temperature perception induces specific defenses that enable C. elegans to cope with the enhanced reactivity of hydrogen peroxide at high temperature

    Francesco A Servello, Rute Fernandes ... Javier Apfeld
    C. elegans nematodes can assess faithfully the threat that H2O2 poses by coupling the induction of their H2O2 defenses to the perception of high temperature—an inherent enhancer of the reactivity of H2O2.

    Positive and negative incentive contrasts lead to relative value perception in ants

    Stephanie Wendt, Kim S Strunk ... Tomer J Czaczkes
    Relative value perception, a basic tenant of Behavioural Economics, is demonstrated in an insect, and further shown to be driven by cognitive processes and induced by private and social information.

    How many neurons are sufficient for perception of cortical activity?

    Henry WP Dalgleish, Lloyd E Russell ... Michael Häusser
    Targeted optogenetic activation of small ensembles of neurons is sufficient to trigger a behavioral report while recruiting matched network suppression, suggesting exquisite sensitivity despite network mechanisms that maintain sparseness.
    1. Neuroscience

    Respiration aligns perception with neural excitability

    Daniel S Kluger, Elio Balestrieri ... Joachim Gross
    Noninvasive human magnetoencephalography recordings characterize the functional relationship between respiration, neural oscillations, and performance in low-level perception.
