  1. 1. Manual Motor Development in Infancy : Execution and Observation of Actions

    Författare :Therese Ljunghammar Ekberg; Gustaf Gredebäck; Claes von Hofsten; Jeffrey J. Lockman; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Infancy; Motor development; Reaching; Actions; Motor prediction; Prospective motor control; Social cognition; Stereopsis; Mirror neuron system; Mu rhythm; Motor impairment; Autism Spectrum Disorder; High-risk siblings; Psychology; Psykologi;

    Sammanfattning : Of all motor skills, manual reaching might be the one ability that matters most for infants’ perceptual, cognitive and social development. Reaching allows infants to learn about object properties, but also gives opportunities for socializing with others. LÄS MER

  3. 2. Neural Control of Movement : Motor Neuron Subtypes, Proprioception and Recurrent Inhibition

    Författare :Anders Enjin; Klas Kullander; Samuel L. Pfaff; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; motor neuron; proprioception; recurrent inhibition; molecular marker; Ia afferent; development; transgenic mice; Renshaw cell; Neurobiology; Neurobiologi; Neuroscience; Neurovetenskap;

    Sammanfattning : Movement is central for life, and all animals depend on accurate regulation of movement for purposeful behavior. There is great diversity of movements, ranging between simple and vital breathing movements to minute and subtle movements of the face used to communicate emotions. LÄS MER

  4. 3. Studies of Spinal Motor Control Networks in Genetically Modified Mouse Models

    Sammanfattning : Spinal neurons are important in several aspects motor control. For example, the neurons essential for locomotor movements reside in the ventral spinal cord. In this thesis, different motor control functions are being related to neuronal populations defined by their common expression of a gene. LÄS MER

  5. 4. Studies on metals in motor neuron disease

    Författare :Per M Roos; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : A slow but steady increase in neurodegenerative disorders has been noted in recent decades. Degenerations in the nervous system are found in Alzheimer's disease, Parkinson's disease and motor neuron diseases. Amyotrophic lateral sclerosis (ALS) is the most common of the motor neuron diseases. LÄS MER

  7. 5. On the Site of the Lesion in Konzo : Clinical and Neurophysiological Studies on a Non-Progressive Upper Motor Neuron Disorder

    Författare :Desire Tshala-Katumbay; Andrew Eisen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Konzo; upper motor neuron diseases; WHO criteria; electroencephalography; evoked potentials; brain involvement; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Sammanfattning : Konzo is a permanent spastic para/tetraparesis occurring in undernourished populations in Africa relying on insufficiently processed bitter cassava, which contains cyanogenic compounds, as staple food. Its pathogenetic mechanism is unknown. Our studies aimed at clarifying the lesion in konzo. LÄS MER
