  1. 1. Cytoskeletal mechanisms in synaptic vesicle recycling

    University dissertation from Stockholm : Karolinska Institutet, Department of Neuroscience

    Author : Jenny Gustafsson; Karolinska Institutet.; Karolinska Institutet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Synapse; actin cytoskeleton; synaptic vesicle; endocytosis;

    Abstract : This thesis explores cytoskeletal mechanisms involved in the recycling of synaptic vesicles. As an initial step it characterizes synapses formed by giant reticulospinal axons in lamprey and defines their use as a model system. The most common type of reticulospinal synapse, "simple synapse", appeared to be most suitable as an experimental model. READ MORE

  2. 2. Zinc-enriched neurons in the spinal cord, cerebellum and peripheral sympathetic system

    University dissertation from Göteborg

    Author : Zhan-You Wang; Göteborgs universitet.; Gothenburg University.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; autometallography; axonal transport; confocal laser scanning microscopy; immuno-electron microscopy; immunofluorescence; inhibitory neurons; sympathetic neurons; synaptic vesicles; zinc ions; zinc transporter;

    Abstract : Zinc ions are abundant in the nervous system and are involved in many biological functions. Most zinc is tightly bound to macromolecules, whereas a small fraction of zinc exists in synaptic vesicles of the zinc-enriched (ZEN) neurons, and can be visualized using various histochemical techniques, including autometallography (AMG).

  3. 3. 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

  4. 4. Mechanisms underlying sustained synaptic release of glutamate

    University dissertation from Stockholm : Karolinska Institutet, false

    Author : Oleg Shupliakov; Karolinska Institutet.; Karolinska Institutet.; [1996]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; synaptic transmission; synaptic vesicle proteins; synapsin; glutamate; glutamine; glutamate uptake; glia; spinal cord; hippocampus; neuromuscular junction; lamprey; crayfish; mouse.;

    Abstract : Fast communication between neurons in the brain is mediated mainly by amino acidtransmitters, such as glutamate, GABA and glycine. These transmitters are stored in smallsynaptic vesicles which undergo exocytosis at synaptic release sites (active zones) in responseto action potentials. READ MORE

  5. 5. Synaptic vesicle endocytosis studied in a living synapse

    University dissertation from Stockholm : Karolinska Institutet, Department of Neuroscience

    Author : Helge Gad; Karolinska Institutet.; Karolinska Institutet.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; synapse; synaptic vesicles; endocytosis; clathrin; calcium; dynamin; endophilin; amphiphysin; synaptojanin; microinjection; electron microscopy;

    Abstract : Neurons in the central nervous system communicate by transmitting electrical signals at special sites of contact called synapses. Synapses contain neurotransmitter-filled synaptic vesicles, which fuse with the presynaptic plasma membrane. The neurotransmitter diffuses to the neighboring neuron and triggers a new electrical signal. READ MORE
