  1. 26. Modelling conversion of adult skin cells to neurons

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Viktor Drugge; [2018]
    Keywords : Human adult fibroblast; Neuron; Neural conversion; Transdifferentiation; Direct reprogramming; Direct lineage conversion; Simulation; Regulatory gene network; Gene network topology; Gene circuit; Gene dynamics; Physics and Astronomy;

    Abstract : Scientists are now able to directly convert one somatic cell type into another using a procedure known as direct lineage reprogramming or transdifferentiation. In this procedure, transcription factors which are important for initiating a rewriting of the gene expressions are introduced in the cell. READ MORE

  3. 27. Neurobiology of opioid addiction

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Ludvig Rudén; [2018]
    Keywords : Opioids; reinforcement; mu opioid receptor; addiction; allostasis; cAMP; Opioider; belöning; mu opioid receptor; beroende; allostas; cAMP;

    Abstract : Since the use of opioids started to emerge for analgesic reasons in the 19th century with the synthetization of morphine, opioids have been studied rigorously to better understand its effects on the brain. This thesis shows that both the analgesic effects and the reinforcing effects of opioids are mediated by the same receptor, the mu opioid receptor (MOR). READ MORE

  4. 28. The key role of dopamine as the neural correlate of intrinsic motivation and trait plasticity

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Lars Temnerud; [2018]
    Keywords : dopamine; intrinsic motivation; metatrait plasticity; personality neuroscience; the five factor model; exploration;

    Abstract : Self-determination theory (SDT), a motivation theory, consists of motivation types: intrinsic motivation, extrinsic motivation, and amotivation, where the social environment is important. SDT’s motivation orientations are about individual differences in people’s tendencies to orient towards environments. READ MORE

  5. 29. The mechanisms of addiction and impairments related to drug use

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Emelie Eeli; [2018]
    Keywords : Addiction; drug abuse; mesocorticolimbic system; cognitive impairments; affective impairments;

    Abstract : This thesis contains an overview of the mechanisms of addiction as well as a description of the impairments related to drug abuse. The general view of addiction is that it depends on three characteristics that have separate neural mechanisms, called “wanting”, liking and learning. READ MORE

  6. 30. Simulating Direct Conversion of Adult Fibroblasts to Neurons

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Joakim Eriksson; [2017]
    Keywords : Computational; Biology; Direct; Conversion; Physics and Astronomy;

    Abstract : Regenerative medicine offers a great prospect for curing diseases. Scientists are using direct conversion to reprogram fibroblasts, a kind of skin cell, into neurons in an attempt to cure Parkinson's disease. READ MORE
