  1. 6. Activity-dependent changes of synaptic transmission in a long-term perspective and processes involved

    Författare :Mikhail Dozmorov; Göteborgs universitet; []
    Nyckelord :synaptic plasticity; hippocampus; LTP; LTD; AMPA; NMDA; protein synthesis;

    Sammanfattning : Synaptic plasticity is an essential property of the central nervous system. It is thought torepresent a mechanism for memory aquisition, storage and recall. The most well studied forms ofsynaptic plasticity are homosynaptic NMDAR-dependent LTP and LTD in the hippocampus inducedby specific patterns of electrical stimulation. LÄS MER

  3. 7. Neuropeptide release in the rat dorsal horn in models of persistent pain : effects of opioids

    Författare :Abdullahi Warsame Afrah; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Axotomy; Inflammation; Long term potentiation; Capsaicin; Opioids; Cholecystokinin; Substance P; Glutamate; NMDA; Spinal cord; Microdialysis; Radioimmunoassay.;

    Sammanfattning : Nerve injury and tissue inflammation may lead to exaggerated responses to both noxious stimuli (hyperalgesia) and innocuous stimuli (allodynia). Altered release pattems of neurotransmitters in the dorsal hom of the spinal cord have been suggested to contribute to hyperalgesia and allodynia. LÄS MER

  4. 8. Effects of ethanol on muscarinic acetylcholine receptors in nerve cells

    Författare :Murielle Hellsten Caron; Institutionen för laboratoriemedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk kemi; Clinical chemistry; nerve cell; SH-SY5Y; NOS; PKC; PLC; Ethanol; mAChR;

    Sammanfattning : This thesis focused on the mechanisms involved in the effects of long-term ethanol treatment on mAChRs and their coupled-signal transduction pathway in human neuroblastoma SH-SY5Y cells. All 5 subtypes of mAChRs were expressed in these cells. LÄS MER

  5. 9. Effects of ethanol on the expression of immediate-early genes in nerve cells

    Författare :Wei-Qun Ding; Institutionen för laboratoriemedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuroadaptation; the central nervous system; AP-1; junD; junB; c-jun; fosB; c-fos; neuroblastoma SH-SY5Y; ethanol; immediate-early genes; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Immediate-early genes of the fos and jun families encode proteins that dimerize to form a complex of activator protein 1 and regulate the expression of a number of genes in the nervous system. Ethanol has previously been shown to induce alterations in expression of fos and jun genes in the brain. LÄS MER

  7. 10. Neuromodulation via endocannabinoids and nitric oxide in the lamprey spinal cord

    Författare :Alexandros Kyriakatos; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The overall objective of this thesis is to increase our understanding of neural networks generating locomotion. These networks called Central Pattern Generators (CPG), are localized in the spinal cord and can generate the basic locomotor pattern in the absence of sensory or supraspinal inputs. LÄS MER
