    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.

    Stage-dependent remodeling of projections to motor cortex in ALS mouse model revealed by a new variant retrograde-AAV9

    Barbara Commisso et al.
    The projections from discrete areas to motor cortex increase over disease course in motoneuron disease model with selective spatial and temporal patterns.
    1. Neuroscience

    Independent representations of ipsilateral and contralateral limbs in primary motor cortex

    Ethan A Heming et al.
    Neural recordings demonstrate how information about the contralateral limb can be isolated from the ipsilateral limb in motor cortex.

    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.
    1. Neuroscience

    Target-specific membrane potential dynamics of neocortical projection neurons during goal-directed behavior

    Takayuki Yamashita, Carl CH Petersen
    A learning-induced, motor-related, projection-specific signal from S1 to S2 accompanies reward-based-learning of a goal-directed sensorimotor transformation of whisker sensation into licking motor output.
    1. Neuroscience

    Feedforward motor information enhances somatosensory responses and sharpens angular tuning of rat S1 barrel cortex neurons

    Mohamed Khateb et al.
    Primary motor cortex afferents supra-linearly amplify the responses and sharpen angular tuning of neurons in the S1 barrel cortex.
    1. Neuroscience

    A critical re-evaluation of fMRI signatures of motor sequence learning

    Eva Berlot et al.
    A systematic assessment of previously proposed fMRI metrics of motor sequence learning reveals widespread activity reductions and subtle multivariate pattern changes outside of primary motor cortex.
    1. Neuroscience

    Local GABA concentration is related to network-level resting functional connectivity

    Charlotte J Stagg et al.
    In the brain at rest, the degree of coordinated activity within the motor network is inversely related to levels of the inhibitory transmitter GABA in primary motor cortex.
    1. Neuroscience

    Object vision to hand action in macaque parietal, premotor, and motor cortices

    Stefan Schaffelhofer, Hansjörg Scherberger
    The cortical grasping circuit separates but shares visual and motor processes to transform object attributes into appropriate hand movements.

    Dynamic range adaptation in primary motor cortical populations

    Robert G Rasmussen et al.
    Motor neurons adjust their sensitivity to direction of movement in a manner analogous to how neurons in the visual system adjust their sensitivity to light.
