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

    Författare :Marcus Petersson; Erik Fransén; Abdel El Manira; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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;

    Sammanfattning : 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. LÄS MER

  2. 2. Free energy calculations of G protein-coupled receptor modulation : New methods and applications

    Författare :Willem Jespers; Hugo Gutiérrez-de-Terán; Johan Åqvist; Jonathan Essex; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; G protein-coupled receptor; adenosine receptor; molecular dynamics; free energy perturbation; homology modeling; computer simulations; conformational selectivity; binding free energy.; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : G protein-coupled receptors (GPCRs) are membrane proteins that transduce the signals of extracellular ligands, such as hormones, neurotransmitters and metabolites, through an intracellular response via G proteins. They are abundant in human physiology and approximately 34% of the marketed drugs target a GPCR. LÄS MER

  3. 3. Dendritic and axonal ion channels supporting neuronal integration : From pyramidal neurons to peripheral nociceptors

    Författare :Marcus Petersson; Erik Fransén; Theodore Cummins; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ion channels; computational modeling; simulations; dendrites; axons; TRP; hippocampus; C-fiber nociceptors; pain;

    Sammanfattning : The nervous system, including the brain, is a complex network with billions of complex neurons. Ion channels mediate the electrical signals that neurons use to integrate input and produce appropriate output, and could thus be thought of as key instruments in the neuronal orchestra. LÄS MER

  4. 4. Modeling receptor induced signaling in MSNs : Interaction between molecules involved in striatal synaptic plasticity

    Författare :Anu G. Nair; Jeanette Hellgren Kotaleski; Omar Gutierrez-Arenas; Upinder S. Bhalla; Pierre Vincent; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; Striatal synaptic plasticity; LTP; Dopamine; Acetylcholine; Synergy; Medium spiny neurons; MSNs;

    Sammanfattning : Basal Ganglia are evolutionarily conserved brain nuclei involved in several physiologically important animal behaviors like motor control and reward learning. Striatum, which is the input nuclei of basal ganglia, integrates inputs from several neurons, like cortical and thalamic glutamatergic input and local GABAergic inputs. LÄS MER

  5. 5. Modeling Biochemical Network Involved in Striatal Dopamine Signaling

    Författare :Anu G. Nair; Jeanette Hellgren Kotaleski; Omar Gutierrez Arenas; Upinder Singh Bhalla; Jakob Kisbye Dreyer; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; Dopamine signaling; Striatum; Reward learning; Acetylcholine; Mass-action modeling; FRET biosensor; Adenosine; Eligibility trace; Datalogi; Computer Science;

    Sammanfattning : In this thesis, I studied the molecular integration of reward-learning related neuromodulatory inputs by striatal medium-sized projection neurons (MSNs) using mass-action kinetic modeling.It is known that, in reward learning, an unexpected reward results in transient elevation in dopamine (peak) whereas omission of an expected reward leads to transient dopamine decrease (dip).
