  1. 6. To grip and not to slip : sensorimotor mechanisms in reactive control of grasp stability

    Författare :Charlotte Häger Ross; Roland S. Johansson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human; hand; precision grip; grasp force; friction; cutaneous mechanoreceptors; sensorimotor integration; motor control;

    Sammanfattning : The reactive control of fingertip forces maintaining grasp stability was examined in man during a prehensile task. Blindfolded subjects used the precision grip between the tips of index finger and thumb to restrain an object that was subjected to unpredictable load forces. These were delivered tangential to the parallel grip surfaces of the object. LÄS MER

  3. 7. Spinal Cord Processing of Sensory Information: Spatial Organization and Adaptive Mechanisms

    Författare :Anders Levinsson; Malmö Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neurophysiology; neuropsychology; Neurology; transplantatioin; pain; sensorimotor; plasticity; reflex; neuropsykologi; neurofysiologi;

    Sammanfattning : Principles for sensorimotor transformation and plasticity in the spinal cord and functional repair in the root-avulsed spinal cord were studied. A comparative study confirmed that the nociceptive withdrawal reflex (NWR) system is composed of reflex modules, with each performing a finely tuned transformation of skin sensory input to activity in one muscle.

  4. 8. Spontaneous Movements during Sleep Guide Spinal Self-organization: Formation and Expression of a Memory Trace

    Författare :Per Petersson; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neuropsychology; Neurology; long-term memory; somatosensory; receptive field; learning; sensorimotor; developmental; neurophysiology; neurofysiologi; neuropsykologi;

    Sammanfattning : During development, information about the three-dimensional shape and mechanical properties of the body is laid down in the synaptic connectivity of sensorimotor systems through adaptive mechanisms. In spinal reflex systems, this enables the fast transformation of complex sensory information into adequate correction of movements. LÄS MER

  5. 9. On the Move : Science and Development Behind Learning Sensorimotor Contingencies in the Mobile Paradigm

    Författare :Umay Sen; Gustaf Gredebäck; Pär Nyström; Philippe Rochat; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sensorimotor contingencies; mobile paradigm; scientific crisis; response differentiation; Psychology; Psykologi;

    Sammanfattning : Exploring the body and environment is essential for development. Detecting and learning contingent relationships between one’s own actions and their consequences instantiates such exploration. Furthermore, it facilitates the development of sense of agency, body awareness, and consciousness. LÄS MER

  7. 10. Cursed complexity. Computational properties of subcortical neuronal microcircuitry in sensorimotor control

    Författare :Anton Spanne; Hjärnans sensorimotoriska funktioner; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; spike firing statistics; spontaneous activity; sensorimotor control; tactile processing; cuneate nucleus; sparse coding; spinal border cells; cerebellum;

    Sammanfattning : One of the big obstacles for understanding the nervous system is its inherent complexity. It poses problems when interpreting both experimental and theoretical studies since we are currently forced to consider only reduced variants of the actual circuitry of the brain. LÄS MER
