  1. 1. Ontogenetic and comparative aspects of cerebellar and motor development

    Detta är en avhandling från Division of Neuroscience, Department of Experimental Medical Sciences, Lund University

    Författare :Maria Christensson; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; Neurologi; Neurology; neuropsychology; Medicine human and vertebrates ; time-translation; cross-species; cerebellum; motor adaptation; development; ferret; external granular layer; neuropsykologi; neurofysiologi; Medicin människa och djur ;

    Sammanfattning : During the course of development the motor repertoire of animals and humans alike go through dramatic changes. New motor patterns arise; movements become coordinated, improve in precision and are at the same time continuously calibrated to the changing body dimensions. The cerebellum is critical for movement coordination and adaptation in adults. LÄS MER

  2. 2. The Cerebello-Olivary Feedback System

    Detta är en avhandling från Department of Experimental Medical Science, Lund Univeristy

    Författare :Fredrik Bengtsson; Lunds universitet.; Lund University.; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurofysiologi; neuropsykologi; neurophysiology; Neurology; neuropsychology; Fysiologi; Physiology; Cerebellum; Purkinje cell; Inferior olive; Neurologi; Nucleo-olivary; Climbing fibre.; Deep cerebellar nuclei;

    Sammanfattning : The pathway from the deep cerebellar nuclei to the inferior olive, the nucleo-olivary pathway, is known to be inhibitory. The physiological and temporal properties, as well as the localisation, of the nucleo-olivary pathway were characterised in the decerebrate ferret. LÄS MER

  3. 3. Cerebellar Control of Classical Conditioning

    Detta är en avhandling från Department of Physiological Sciences, Lund University

    Författare :Magnus Ivarsson; Lunds universitet.; Lund University.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bilateral; Associative module; Orbicularis oculi muscle; Inferior olive; Purkinje cell; Eyeblink; Conditioned response; neuropsykologi; neurofysiologi; Neurologi; neurophysiology; neuropsychology; Neurology;

    Sammanfattning : It has previously been shown that the cerebellum is critical for classical conditioning. The experiments presented in this thesis aimed to study how the cerebellum controls conditioned eyeblink responses (CRs) and specifically the efferent path from the cerebellar cortex to the muscles.

  4. 4. Functional Organization of Cerebellar Modules Controlling Forelimb Movements: Climbing and Mossy Fibre Input and Motor Output via the Red Nucleus and Motor Cortex

    Detta är en avhandling från Department of Physiology and Neuroscience, Lund University

    Författare :Henrik Jörntell; Lunds universitet.; Lund University.; [1997]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neuropsykologi; neurofysiologi; Neurology; neuropsychology; neurophysiology;

    Sammanfattning : A modular organization has recently been described for the cerebellar control system comprising the forelimb areas of the C1/C3/Y zones in the cerebellar cortex and nucleus interpositus anterior (NIA) of the cat. A module is a group of cells in NIA which receives homogenous climbing fibre input via Purkinje cells that belong to the same set of microzones in the C1/C3/Y zones. LÄS MER

  5. 5. Molecular mechanisms of synaptic transmission and plasticity in spinal sensory pathways

    Detta är en avhandling från Faculty of Medicine, Lund University

    Författare :Max Larsson; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; neurophysiology; Neurology; electron microscopy; synaptic plasticity; synapse; pain; spinal cord; hyperalgesia; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : An intense, potentially tissue-damaging (noxious) stimulus may lead to enhanced pain sensation of subsequent noxious stimuli (hyperalgesia) and to the perceiving of innocuous stimuli as painful (allodynia). This is thought to result to a large extent from strengthening of synapses established by primary afferent fibers onto spinal cord dorsal horn neurons. LÄS MER
