  1. 1. Programming and updaing of reaching movements

    Författare :Sergei Perfiliev; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Reaching movements; motor cortex; central command; neuronal recording; trajectory updating; descending pathways; spinal cord lesions;

    Sammanfattning : Neuronal activity in the motor cortex (area 4) was recorded during reaching movements in cats, trained to perform target-reaching in response to a tone burst. Out of 350 task related neurones 12% generated short latency (20?110 ms) sensory responses to the cue triggering the reaching movement. LÄS MER

  3. 2. Visual and proprioceptive control of arm movements : studies of development and dysfunction

    Författare :Birgit Rösblad; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vision; proprioception; reaching; pointing; arm movements; child; motor impairments; sensorimotor development;

    Sammanfattning : The aim of this dissertation was to examine the role of sensory information for control of goal-directed arm movements in children. The role of visual and proprioceptive information on the target for end point accuracy was examined in normal 4- to 12-year- old children (Study I), and in children with motor impairments (Study II).

  4. 3. Mobility, Sitting Posture and Reaching Movements in Children with Myelomeningocele

    Författare :Simone Norrlin; Lennart von Wendt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; myelomeningocele; PEDI; mobility; sitting posture; reaching; motor adaptation; Pediatrik; Paediatric medicine; Pediatrisk medicin; pediatrik; Pediatrics;

    Sammanfattning : Children with myelomeningocele (MMC) usually have problems with daily life activities, but the background to their problems is not altogether obvious. An understanding of the possible causes of activity problems is a prerequisite for the effectiveness of physical therapy. LÄS MER

  5. 4. Delayed Development of Visuomotor Capacity in Very Preterm Infants

    Författare :Katarina Strand Brodd; Uwe Ewald; Gerd Holmström; Bo Strömberg; Claes von Hofsten; Louise Rönnqvist; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preterm infants; visual development; neurosensory development; smooth pursuit eye movements; perinatal risk factors; reaching movements; Paediatric medicine; Pediatrisk medicin; Pediatrik; Pediatrics;

    Sammanfattning : To coordinate visual perception and motor control in daily life where we are constantly surrounded by motion, we are dependent on normal visuomotor capacity. One essential prerequisite for normal visuomotor capacity is smooth pursuit eye movements (SP). Infants born very preterm (VPT = born .. LÄS MER

  7. 5. From Motion to Movements : Revelations by the Infant EEG

    Författare :Pär Nyström; Claes von Hofsten; Riitta Hari; Uppsala universitet; []
    Nyckelord :Psychology; infant; brain; EEG; mirror neurons; ERP; ICA; MNS; Psykologi;

    Sammanfattning : The introduction of high density EEG (hd-EEG) nets for easy application on subjects of all ages has improved the possibilities to investigate the development of the infant neurophysiology. This dissertation consists of three studies (I – III) that investigate the visual motion system and mirror neuron system of the infant, and methodological sections that outline the bioelectrical background and the characteristics of the methods used.
