  1. 1. The Cerebello-Olivary Feedback System

    University dissertation from Department of Experimental Medical Science, Lund Univeristy

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

    Abstract : 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. READ MORE

  2. 2. Cerebellar Control of Classical Conditioning

    University dissertation from Department of Physiological Sciences, Lund University

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

    Abstract : 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.

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

    University dissertation from Department of Physiology and Neuroscience, Lund University

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

    Abstract : 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. READ MORE

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

    University dissertation from Faculty of Medicine, Lund University

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

    Abstract : 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. READ MORE

  5. 5. Itch and Pain Inhibitory Mechanisms in Humans - evidence for a differential control of nociceptive senses

    University dissertation from Hans-Jörgen Nilsson, Dept of Physiological Sciences, Sölvegatan 19, 223 62 Lund, Sweden

    Author : Hans-Jörgen Nilsson; Lund University.; Lunds universitet.; [1999]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; Neurology; Human; TENS; Somatosensory; Pruritus; Analgesia; Pain; Nociception; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Abstract : It is known that stimulation of thin nerve afferents can inhibit itch and pain and that the nociceptive systems have a detailed topographical organisation, with subsystems exhibiting specific excitatory and inhibitory receptive fields. On this basis, a new technique was developed, termed Cutaneous Field Stimulation (CFS), that electrically stimulates thin nerve fibers innervating specific skin fields. READ MORE
