    Perception as a closed-loop convergence process

    Ehud Ahissar, Eldad Assa
    Perception is proposed to be a dynamic motor-sensory closed-loop process in which information flows through the environment and the brain in continuous loops, converging towards steady-state percepts.

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

    Mohamed Khateb, Jackie Schiller, Yitzhak Schiller
    Primary motor cortex afferents supra-linearly amplify the responses and sharpen angular tuning of neurons in the S1 barrel cortex.

    Self-configuring feedback loops for sensorimotor control

    Sergio Oscar Verduzco-Flores, Erik De Schutter
    Learning to reach in the sensorimotor loop, and the required neural dynamics, can be potentially explained by simple principles.

    Nested mechanosensory feedback actively damps visually guided head movements in Drosophila

    Benjamin Cellini, Jean-Michel Mongeau
    Motor context and mechanosensory feedback together influence how flies control head movements during visually guided flight maneuvers.

    Sensorimotor feedback loops are selectively sensitive to reward

    Olivier Codol, Mehrdad Kashefi ... Paul L Gribble
    Motor performance benefits from rewarding contexts via a non-uniform reduction of response latencies and increase in feedback gains across the feedback loops involved in upper limb motor control.

    Circuit organization of the excitatory sensorimotor loop through hand/forelimb S1 and M1

    Naoki Yamawaki, Martinna G Raineri Tapies ... Gordon MG Shepherd
    Cell-type-specific circuit analysis reveals a highly polysynaptic pattern of excitatory feedforward connections along the somatosensory-to-motor loop, from cuneate via VPL thalamus to S1 and M1 cortex and corticospinal neurons.

    Saccadic suppression as a perceptual consequence of efficient sensorimotor estimation

    Frédéric Crevecoeur, Konrad P Kording
    Neural computations necessary for efficient control of saccades capture the phenomenon of saccadic suppression, which suggests that neural resources are shared for perception and control.

    Disrupting cortico-cerebellar communication impairs dexterity

    Jian-Zhong Guo, Britton A Sauerbrei ... Adam W Hantman
    The flow of neural activity across the cortico-cerebellar loop enables mice to reach for objects with skill and precision.

    Variability in locomotor dynamics reveals the critical role of feedback in task control

    Ismail Uyanik, Shahin Sefati ... Noah J Cowan
    Animals rely on sensory feedback rather than the precise tuning in the nervous system to achieve robust behavioral performances.

    Distance estimation from monocular cues in an ethological visuomotor task

    Philip RL Parker, Elliott TT Abe ... Cristopher M Niell
    Mice accurately perform an ethological distance estimation task based on gap jumping and can use monocular cues to estimate distance in addition to binocular cues such as stereopsis.
