  1. 6. Neurobiological Consequences of Social Conditions and Alcohol Exposure in Adolescent rats

    Författare :Linnea Granholm; Ingrid Nylander; Anne-Lie Svensson; Erika Roman; Maria Ellgren; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adolescence; alcohol; amphetamine; dopamine; dorsal striatum; dynorphin; endogenous opi- oids; enkephalin; high-speed chronoamperometry; housing conditions; rats; nociceptin orphanin FQ; radi- oimmunoassay; self-administration; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Adolescence represents a time of extensive reorganisation and maturation of brain circuits involved in emotions, motivation and cognition and it is a period particular sensitive for external stimuli. External stimuli can be both socio-environmental factors and exposure to exogenous compounds such as drugs of abuse (e.g. alcohol). LÄS MER

  2. 7. Epigenetic Dysregulations in the Brain of Human Alcoholics : Analysis of Opioid Genes

    Författare :Igor Bazov; Georgy Bakalkin; Catharina Lavebratt; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neuropeptides; dynorphin; human brain; alcohol dependence; epigenetics; gene transcription;

    Sammanfattning : Neuropeptides are special in their expression profiles restricted to neuronal subpopulations and low tissue mRNA levels. Genetic, epigenetic and transcriptional mechanisms that define spatiotemporal expression of the neuropeptide genes have utmost importance for the formation and functions of neural circuits in normal and pathological human brain.

  3. 8. Adolescent behavior : Links to early-life stress and alcohol in male and female rats

    Författare :Stina Lundberg; Erika Roman; Ingrid Nylander; Heidi MB Lesscher; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adolescence; alcohol exposure; behavior; corticosterone; dynorphin; early life; endogenous opioid peptides; Met-enkephalin-Arg6Phe7 MEAP ; individual differences; multivariate concentric square field MCSF ; phenotyping; radioimmunoassay; selective breeding for alcohol consumption; voluntary alcohol intake; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Adolescence is an important developmental phase with large changes in behavior, physiology and neurobiology, which transform an individual from immature child to independent adult. Due to these changes, adolescence is a sensitive period for exposure to environmental factors such as stress and drug exposure; it is also a common age of onset for alcohol consumption as well as several psychiatric disorders.

  4. 9. Stress, Drugs and Neuroscience : Neurobiological Effects of Social Stressors and Drug Exposure in Young and Adolescent Rats

    Författare :Linnea Granholm; Ingrid Nylander; Erika Roman; Anne-Lie Svensson; Maria Ellgren; Annika Thorsell; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adolescence; alcohol exposure; amphetamine; beta-endorphin; dopamine; dynorphin; early life; endogenous opioids; enkephalin; gene expression; high-speed chronoamperometry; nociceptin orphanin FQ; radioimmunoassay; self-administration; social stress; voluntary alcohol intake; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Experiences early in life or during adolescence modulate neuronal networks in the immature brain and consequently lay the foundation for future susceptibility or resilience towards psychiatric disorders. The objective in this thesis is to understand, in part, how the surrounding environment shapes the brain of a young individual. LÄS MER

  5. 10. Maternal Separation in the Rat : The Short- and Long-term effects of Early-life Experience on Neuropeptides, Monoamines and Voluntary Ethanol Consumption

    Författare :Sadia Oreland; Ingird Nylander; Joram Feldon; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Early-life stress; Handling; Serotonin; Dopamine; Oxytocin; Vasopressin; Enkephalin; Dynorphin; Two-bottle free choice; Maternal deprivation; Pharmaceutical pharmacology; Farmaceutisk farmakologi; Farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Sammanfattning : Early-life experience has profound effects on the individual’s neurobiology and behaviour later in life. The rodent animal experimental model maternal separation (MS) was used to study this more in detail. The MS model involves short and prolonged postnatal separations simulating an emotionally safe and stressful environment, respectively. LÄS MER
