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

    Author : Linnea Granholm; Ingrid Nylander; Erika Roman; Anne-Lie Svensson; Maria Ellgren; Annika Thorsell; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 7. Machine learning for identification of brain activity patterns with applications in gentle touch processing

    Author : Malin Björnsdotter Åberg; Göteborgs universitet; []
    Keywords : Somatosensory; Machine learning; Pattern recognition; fMRI; Support vector machines; Neuroscience; Brain; BOLD; Signal processing; Artificial intelligence; Touch; Human; Unmyelinated; Sensory; Affective;

    Abstract : Since the first mention of artificial intelligence in the 1950s, the field of machine learning has provided increasingly appealing tools for recognition of otherwise unintelligible pattern representations in complex data structures. Human brain activity, acquired using functional magnetic resonance imaging (fMRI), is a prime example of such complex data where the utility of pattern recognition has been demonstrated in a wide range of studies recently (Haynes et al.

  5. 8. Functional Analysis of the Vesicular Glutamate Transporter 2 in Specific Neuronal Circuits of the Brain

    Author : Karin Nordenankar; Åsa Wallén-Mackenzie; Rainer Spanagel; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Addiction; amphetamine; affective behaviour; cocaine; cognitive behaviour; conditional knockout mouse; dopamine; operant self-administration; reward system; schizophrenia; Neuroscience; Neurovetenskap;

    Abstract : A key issue in neuroscience is to determine the connection between neuronal circuits and behaviour. In the adult brain, all neuronal circuits include a glutamatergic component. READ MORE

  6. 9. SACRED or NEURAL? : Neuroscientific Explanations of Religious Experience: A Philosophical Evaluation

    Author : Anne L. C. Runehov; Mikael Stenmark; J. Wentzel van Huyssteen; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; Philosophy of religion; Neuroscience; Neurotheology; Persinger; d Aquili; Newberg; neuroimaging technology; epilepsy; meditation; explanatory models; reductionism; religious experience; science and theology; Religionsfilosofi; Philosophy of religion; Religionsfilosofi; Philosophy of Religion; religionsfilosofi;

    Abstract : Neuroscientists place different explanations at our disposal of what religious experiences are. Some neuroscientists explain religious experiences in terms of consequences of a damaged, malfunctioning or mentally deranged brain. Others explain them in terms of existential crises. READ MORE

  7. 10. Revealing Secrets of Synaptic Protein Interactions : A Biosensor based Strategy

    Author : Christian Seeger; U Helena Danielson; Sarah Lummis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surface plasmon resonance; biosensor; AMPA receptor; GABAA receptor; ligand-gated ion channel; A-kinase anchoring protein; caldendrin; calmodulin; HIV; fragment based drug discovery; Biokemi; Biochemistry; Neuroscience; Neurovetenskap;

    Abstract : Protein interactions are the basis of synaptic function, and studying these interactions on a molecular level is crucial for understanding basic brain function, as well as mechanisms underlying neurological disorders. In this thesis, kinetic and mechanistic characterization of synaptic protein interactions was performed by using surface plasmon resonance biosensor technology. READ MORE
