  1. 1. Developmental plasticity of the glutamate synapse: Roles of low frequency stimulation, hebbian induction and the NMDA receptor

    Author : Joakim Strandberg; Göteborgs universitet; []
    Keywords : AMPA receptor; Development; Glutamate; Hippocampus; Long-term depression; Long-term potentiation; NMDA receptor; Synaptic depression;

    Abstract : The glutamate synapse is by far the most common synapse in the brain and acts via postsynaptic AMPA, NMDA and mGlu receptors. During brain development there is a continuous production of these synapses where those partaking in activity resulting in neuronal activity are subsequently selected to establish an appropriate functional pattern of synaptic connectivity while those that do not are elimimated.

  2. 2. Modulation of AMPA glutamate receptor functions in primary neuronal cultures

    Author : Gvido Cebers; Karolinska Institutet; Karolinska Institutet; []
    Keywords : glutamate; AMPA; cerebellar granule cells; cortical cells; cyclothiazide; AP-1; transcription factors; receptor desensitization; Ca2 ; neurotoxicity; 45Ca2 uptake; apoptosis; ischemia; muscarinic; carbachol;

    Abstract : Primary neuronal cultures were used to investigate the properties of AMPA receptors and functional consequences of their activation, as well as AMPA receptor desensitization and possibilities for its modulation. We established the presence and spontaneous functional activity of AMPA receptors in cerebellar granule and cortical cell cultures. READ MORE

  3. 3. Beyond AMPA and NMDA: Slow synaptic mGlu/TRPC currents : Implications for dendritic integration

    Author : Marcus Petersson; Erik Fransén; Abdel El Manira; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transient receptor potential; TRP; metabotropic glutamate receptor; mGlu1 5; dendritic integration; synaptic activation; temporal summation; low-frequency; entorhinal cortex; mathematical model; computational neuroscience; Computer science; Datavetenskap;

    Abstract : In order to understand how the brain functions, under normal as well as pathological conditions, it is important to study the mechanisms underlying information integration. Depending on the nature of an input arriving at a synapse, different strategies may be used by the neuron to integrate and respond to the input. READ MORE

  4. 4. GABA-, glycine- and glutamate-induced currents in rat medial preoptic neurons : functional interactions and modulation by capsaicin

    Author : Urban Karlsson; Staffan Johansson; Johannes Krupp; Bryndis Birnir; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medial preoptic nucleus; synaptic transmission; glutamate; GABA; glycine; TRPV1; Physiology; Fysiologi;

    Abstract : The medial preoptic nucleus (MPN) of the hypothalamus plays a major role in many functions involved in maintaining bodily homeostasis, such as thermoregulation and osmoregulation, as well as in the control of complex behaviours, e.g. sexual behaviour. READ MORE

  5. 5. Anti-epileptic and neuroprotective mechanisms by Topiramate and Levetiracetam evaluated in primary cultures

    Author : Mikael Ängehagen; Göteborgs universitet; []
    Keywords : calcium imaging; phosphorylation; kainate; glutamate; caffeine; cerebral cortex; hippocampus; field potentials; neurons; astrocytes;

    Abstract : The aim of this thesis was to evaluate plausible intracellular mechanisms of action for antiepileptic drugs, Topiramate (TPM) and Levetiracetam (LEV), and to investigate if TPM possesses neuroprotective properties. The thesis is based on results from calcium imaging, immunohistochemical stainings, viability tests, and Western blot using primary cortical or hippocampal cultures, or hippocampal brain slices.
