    Neural basis of somatosensory target detection independent of uncertainty, relevance, and reports

    Pia Schröder et al.
    Neural correlates of somatosensory target detection are restricted to secondary somatosensory cortex, whereas activity in insular, cingulate, and motor regions reflects stimulus uncertainty and overt reports.

    Transcriptional profiling at whole population and single cell levels reveals somatosensory neuron molecular diversity

    Isaac M Chiu et al.
    Molecular analysis paints a detailed picture of the distinctiveness and complexities of peripheral somatosensory neurons.

    The causal role of the somatosensory cortex in prosocial behaviour

    Selene Gallo et al.
    A combination of human imaging and brain stimulation techniques show that the somatosensory cortex is essential to prosocial decision making, by transforming observed pain in accurate perception of others' distress.

    Stereotyped transcriptomic transformation of somatosensory neurons in response to injury

    Minh Q Nguyen et al.
    Peripheral injury induces a programmed but reversible transformation of gene expression in somatosensory neurons providing a mechanism to regulate sensory input during wound healing.

    Area 2 of primary somatosensory cortex encodes kinematics of the whole arm

    Raeed H Chowdhury et al.
    Area 2 of somatosensory cortex represents kinematic details of the entire arm during movement, but this mapping from limb state to neural activity differs for reaching and passive limb displacement.

    High-order thalamic inputs to primary somatosensory cortex are stronger and longer lasting than cortical inputs

    Wanying Zhang, Randy M Bruno
    Secondary thalamic nuclei may provide stronger, longer-lasting input to superficial layers of primary sensory cortex than other cortical areas can.

    nNOS-expressing interneurons control basal and behaviorally evoked arterial dilation in somatosensory cortex of mice

    Christina T Echagarruga et al.
    The diameter of cortical arteries is not controlled by the overall neural activity, but rather by a subset of specialized neurons.

    Perceptually relevant remapping of human somatotopy in 24 hours

    James Kolasinski et al.
    A combination of 7 tesla fMRI and psychophysics revealed the reorganisation of the human somatosensory cortex and changes in tactile perceptual abilities after just 24 hours of altered hand use.

    Proprioceptive and cutaneous sensations in humans elicited by intracortical microstimulation

    Michelle Armenta Salas et al.
    Electrical microstimulation of human somatosensory cortex elicited purely naturalistic proprioceptive and cutaneous sensations, with proprioceptive sensations more prominent at higher current amplitudes suggesting a relationship between amplitude and sensation type.

    A mutant with bilateral whisker to barrel inputs unveils somatosensory mapping rules in the cerebral cortex

    Nicolas Renier et al.
    The somatosensory cortex doesn't integrate mixed bilateral inputs, as partially uncrossing projections from the whiskers duplicates their representation by segregating lateralized inputs from each side of the head.
