    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.

    Beta band oscillations in motor cortex reflect neural population signals that delay movement onset

    Preeya Khanna, Jose M Carmena
    Using a sequential neurofeedback-arm reaching task, a new link is established among population neural activity patterns, generation of beta oscillations, and motor behavior changes.

    A comprehensive excitatory input map of the striatum reveals novel functional organization

    Barbara J Hunnicutt et al.
    The first comprehensive map of all excitatory inputs to the mouse striatum is presented and used to define and demarcate striatal subdivisions, including a previous unappreciated novel subdivision in the posterior striatum.

    Minimally dependent activity subspaces for working memory and motor preparation in the lateral prefrontal cortex

    Cheng Tang et al.
    The evidence of subspace computation in the lateral prefrontal cortex provides insights into the neural mechanisms underlying cognitive flexibility and interference between different cognitive processes.

    Movement initiation and grasp representation in premotor and primary motor cortex mirror neurons

    Steven Jack Jerjian et al.
    Mirror neurons, including corticospinal neurons, in primary motor cortex of macaque monkeys, clearly dissociate between execution and observation of grasping actions while ventral premotor cortex (F5) maintains a similar representation.
