    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.

    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.

    Intracortical Microstimulation: Regaining the senses of touch and movement

    Victor de Lafuente
    Artificially activating certain neurons in the cortex can make a tetraplegic patient feel naturalistic sensations of skin pressure and arm movement.

    Lifting the veil on the dynamics of neuronal activities evoked by transcranial magnetic stimulation

    Bingshuo Li et al.
    A cellular-level in vivo investigative method that provides unprecedented insights into the dynamics of neuronal activities evoked by transcranial magnetic stimulation.

    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.

    Intraneural stimulation elicits discrimination of textural features by artificial fingertip in intact and amputee humans

    Calogero Maria Oddo et al.
    Delivering specific patterns of electrical activity to the median nerve of the arm triggers reliable sensations of texture, suggesting that it may ultimately be possible to restore complex tactile information to users of prosthetic limbs.

    The corticospinal tract primarily modulates sensory inputs in the mouse lumbar cord

    Yunuen Moreno-Lopez et al.
    While the corticospinal tract is often considered exclusively as a motor path, a combination of intersectional viral strategy and in vivo electrophysiology reveals that, in the mouse lumbar cord, its main role is the modulation of sensory inputs.

    Developmental 'awakening' of primary motor cortex to the sensory consequences of movement

    James C Dooley, Mark S Blumberg
    Early in development, before neurons in primary motor cortex are involved in motor control, they undergo a rapid transition in how they process sensory information following sleep and wake movements.

    Motor cortex signals for each arm are mixed across hemispheres and neurons yet partitioned within the population response

    Katherine Cora Ames, Mark M Churchland
    Neurons in motor cortex contain information about each arm, but these signals are separated into different dimensions, allowing separate control of each arm.

    Cortex-dependent recovery of unassisted hindlimb locomotion after complete spinal cord injury in adult rats

    Anitha Manohar et al.
    After complete spinal transection in adult rats, careful combinations of pharmacological and physical therapies create a novel cortical sensorimotor circuit that may bypass the lesion through biomechanical coupling, allowing animals to recover unassisted hindlimb locomotion.
