  1. 1. On the Mechanisms Behind Hippocampal Theta Oscillations The role of OLMα2 interneurons

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Sanja Mikulovic; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hippocampus; interneuron; optogenetics; theta oscillations; anxiety;

    Sammanfattning : Theta activity is one of the most prominent rhythms in the brain and appears to be conserved among mammals.  These 4-12 Hz oscillations have been predominantly studied in the dorsal hippocampus where they are correlated with a broad range of voluntary and exploratory behaviors.

  2. 2. Molecular Adaptations in the Endogenous Opioid System in Human and Rodent Brain

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Muhammad Zubair Hussain; Uppsala universitet.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endogenous Opioid System; Dynorphins; Lateralization; Alcohol Dependence; Emotions; Traumatic Brain Injury; Anterior Cingulate Cortex; Dorsal Striatum; Neuroscience; Neurovetenskap;

    Sammanfattning : The aims of the thesis were to examine i) whether the endogenous opioid system (EOS) is lateralized in human brain areas involved in processing of emotions and pain; ii) whether EOS responses to unilateral brain injury depend on side of lesion, and iii) whether in human alcoholics, this system is involved in molecular adaptations in brain areas relevant for cognitive control of addictive behavior and habit formation.The main findings were that (1) opioid peptides but not opioid receptors and classic neurotransmitters are markedly lateralized in the anterior cingulate cortex involved in processing of  positive and negative emotions and affective component of pain.

  3. 3. 5-HT receptor-mediated modulation of glutamate transmission in the hippocampus and prefrontal cortex and its relation to cognition and depression

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Clinical Neuroscience

    Författare :Tiberiu Loredan Stan; Karolinska Institutet.; Karolinska Institutet.; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Depression is a multifaceted disease which is marked by cognitive and emotional memory impairments. It is characterised by an imbalacement of serotonergic and glutamatergic system in brain areas such as hippocampus and prefontal cortex. LÄS MER

  4. 4. Brain neurotrophin levels and mouse behavior : relationship to environmental influences

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Clinical Neuroscience, Occupational Therapy and Elderly Care Research (NEUROTEC)

    Författare :Shun-Wei Zhu; Karolinska Institutet.; Karolinska Institutet.; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Environmental Enrichment; Intermittent Individual Housing; Physical Exercise; Anxiety; NGF; BDNF; Dorsal Hippocampus; Ventral Hippocampus;

    Sammanfattning : All normal functions over the lifetime of an animal are based on a dynamic balance of at least three fundamental elements: brain, environment and behaviour. This thesis investigated different aspects of these three elements and revealed novel interactions of brain neurotrophins, environmental influences and emotional behaviour in mice. LÄS MER
