  1. 1. The corticogeniculate synapse : a neuronal amplifier?

    Författare :Björn Granseth; Eric Hanse; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Consciousness is a nervous process that handles only a limited amount of information. Therefore the nervous system needs to select the most relevant input for aware processing. LÄS MER

  3. 2. Plasticity of the developing glutamate synapse in the hippocampus

    Författare :Therése Abrahamsson; Göteborgs universitet; []
    Nyckelord :synaptic plasticity; long-term potentiation; short-term potentiation; silent synapse; development; hippocampus; glutamate;

    Sammanfattning : Synapses are highly plastic, i.e. they have the ability to change their signaling strength both in the short- and long-term (e.g. LÄS MER

  4. 3. Synaptic elimination and the complement system in Alzhaimer's disease

    Författare :Jonny Daborg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Synapse; Alzheimer s disease; Genetics; CSF; Complement; RAGE;

    Sammanfattning : The mechanisms behind Alzheimer’s disease (AD) are largely unknown. The disease is to a large extent hereditary, and the best pathophysiological correlate to the severity of the symptoms is loss of synapses. LÄS MER

  5. 4. Astrocyte-mediated short-term synaptic depression

    Författare :My Andersson; Göteborgs universitet; []
    Nyckelord :glutamate; glia; plasticity; synapse; hippocampus;

    Sammanfattning : Short-term synaptic plasticity, the activity-dependent regulation of synaptic efficacy that occurs in the timeframe of milliseconds to seconds, is a fundamental property of the synapse, mostly attributed to changes in release probability. These changes are commonly ascribed to intrinsic mechanisms in the presynaptic terminal and to different transmitters acting on the presynaptic terminal. LÄS MER

  7. 5. Advanced Fluorescence Microscopy to Study Plasma Membrane Protein Dynamics

    Författare :Joachim Piguet; Horst Vogel; Ruud Hovius; Jerker Widengren; Antoine Triller; Switzerland Ecole Polytechnique Fédérale de Lausanne (EPFL); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence; microscopy; plasma membrane; membrane proteins; membrane proteins diffusion; single-molecule imaging; single-molecule tracking; pentameric ligand-gated ion channels; nicotinic acetylcholine receptor; serotonin receptor; synapse; neuromuscular junction; post-synaptic scaffold; rapsyn; myopathies; fluorescent proteins; Förster resonance energy transfer; FRET imaging; protein-protein interactions; protein trafficking; photo-activatable proteins; Biological Physics; Biologisk fysik;

    Sammanfattning : Membrane protein dynamics is of great importance for living organisms. The precise localization of proteins composing a synapse on the membrane facing a nerve terminus is essential for proper functioning of the nervous system. In muscle fibers, the nicotinic acetylcholine is densely packed under the motor nerve termini. LÄS MER
