  1. 1. Characterization of the synaptic connectivity patterns of genetically defined neuron types in circuits that regulate dopamine and serotonin

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :Alexandros Ikaros Pavlopoulos; [2014]
    Nyckelord :neuroscience; lateral habenula; optogenetics; neuronal populations; neurons; brain; dopamine; serotonin; dual viral system; retrograde viral tracing; globus pallidus; rabies virus; reward; basal ganglia;

    Sammanfattning : The Lateral Habenula (LHb) have been implicated in both reward-seeking behavior and in depressive disorders due to its modulatory effects on dopamine rich areas. Excitatory projections from LHb target GABAergic interneurons of both ventral tegmental area (VTA) and rostromedial tegmental nucleus (RMTg) and consequently provide strong inhibition on VTA‟s dopaminergic neurons.

  3. 2. Energy Efficiency in IP over WDM Networks

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Carlos Ribera; [2013]
    Nyckelord :;

    Sammanfattning : In the last decade, energy efficiency in backbone networks has become an important problem due to the significant growth in the Internet traffic. A very promising solution to solve this problem in Internet Protocol (IP) over Wavelength Division Multiplexing (WDM) networks is the Virtual Topology Adaptation approach, which permits adapting network resources by following a dynamic daily traffic profile.

  4. 3. Dependence-induced changes in opioid-receptor gene expression

    Master-uppsats, Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Författare :Anna Johansson; [2013]
    Nyckelord :Neuropeptides; Alcohol; Gene expression; C57 BL6 mice model; Addiction; VTA; Opioid Receptors; Reward; Quantitative RT-PCR; neoropeptider; gene expression; real tids-PCR;

    Sammanfattning : Using drugs such as alcohol and morphine among others can be addictive in some individuals, and progress into a substance abuse disorder. The mesolimbic dopaminergic system (MD-system) is involved in the reward process during the development of drug addiction. LÄS MER

  5. 4. VTA-aggregatet : En undersökning av driftegenskaper och funktion vid slowsteaming.

    Kandidat-uppsats, Sjöfartshögskolan, SJÖ

    Författare :Edward Lundin; [2011]
    Nyckelord :VTA-turbo; emissions; fuel reduction; slowsteaming; VTA-turbo; emissioner; bränsleförbrukning; slowsteaming;

    Sammanfattning : Turboaggregat med variabel geometri har länge funnit hos automobiler, men det dröjde ända tills 2008 innan det första dök upp på ett fartyg. Syftet med denna undersökning har varit att kontrollera om de fördelar som Man B&W hävdar att VTA-aggregatet skall ha stämmer, samt att undersöka om VTA-aggregatet kan lösa de problem som uppkommer i och med att man kör med reducerad fart, s.

  7. 5. Identification and characterization of genes that are involved in reward mechanisms in ethanol self-administration

    L3-uppsats, SLU/Dept. Of Plant Biology

    Författare :Hung Trinh; [2009]
    Nyckelord :brain reward pathway; ethanol self-administration; neurotransmitter receptor; real-time PCR; mRNA; VTA; NAc; Sn; CPu;

    Sammanfattning : Alcohol addiction is one of the most common drug addictions amongst societies. Alcohol abuse, can lead serious injuries, severe diseases or even death. Despite intensive research, complete knowledge about alcohol addiction and a specific "ethanol receptor" has not been found yet. LÄS MER
