    Neural excitability and sensory input determine intensity perception with opposing directions in initial cortical responses

    Tilman Stephani et al.
    Larger evoked responses during initial cortical processing may reflect states of lower excitability.

    Spinal lumbar dI2 interneurons contribute to stability of bipedal stepping

    Baruch Haimson et al.
    Spinal dI2 interneurons relay peripheral and intraspinal feedback to premotor networks in the spinal cord and the cerebellum to ensure the stability of bipedal stepping.

    Scanned optogenetic control of mammalian somatosensory input to map input-specific behavioral outputs

    Ara Schorscher-Petcu et al.
    A system to generate ‘remote touch’ in freely behaving mice can be utilized to map behavior caused by precise somatosensory inputs.

    Perception of microstimulation frequency in human somatosensory cortex

    Christopher L Hughes et al.
    Increasing microstimulation frequency in some regions of the human somatosensory cortex decreased the perceived intensity and evoked specific percepts, providing insight into cortical organization and sensory feedback approaches for brain–computer interfaces.
    1. Neuroscience

    Sensory coding and the causal impact of mouse cortex in a visual decision

    Peter Zatka-Haas et al.
    Local sensory signals in visual and frontal cortex play a causal role in task performance, while widespread dorsal cortical signals correlating with movement reflect processes that do not.
    1. Neuroscience

    The organizational principles of de-differentiated topographic maps in somatosensory cortex

    Peng Liu et al.
    SI topographic finger maps of older adults show signs of cortical aging but do not show classical hallmarks of cortical de-differentiation.
    1. Neuroscience

    Sniff-synchronized, gradient-guided olfactory search by freely moving mice

    Teresa M Findley et al.
    To track odors borne on turbulent airflow, mice strategically follow their nose, with sampling movements and sensory computations reminiscent of those demonstrated in nematodes and insects.
    1. Neuroscience

    A spinoparabrachial circuit defined by Tacr1 expression drives pain

    Arnab Barik et al.
    A circuit involving Tacr1-expressing neurons in the spinal cord and the parabrachial nucleus controls how mice respond to a wide range of persistently painful stimuli.

    Genetic disruption of WASHC4 drives endo-lysosomal dysfunction and cognitive-movement impairments in mice and humans

    Jamie L Courtland et al.
    Cellular etiology of a human WASH complex mutation in mice reveals its specific roles in neuronal organelle trafficking and a surprising role in motor impairments.
    1. Neuroscience

    Neural encoding of actual and imagined touch within human posterior parietal cortex

    Srinivas Chivukula et al.
    Single neurons in human posterior parietal cortex encode actual and imagined touch within a shared neural substrate.
