  2. 1. Fear, Startle, and Fear-Potentiated Startle : Probing Emotion in the Human Brain

    Author : Anna Pissiota; Mats Fredrikson; Scott Rauch; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; anxiety; attention; brain; fear; fear-potentiated startle; human; neuroimaging; positron emission tomography; posttraumatic stress disorder; regional cerebral blood flow; startle; startle habituation; symptom provocation; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : The present thesis explored the neurobiological basis of three aspects of defense behaviors in humans. Positron emission tomography methodology was used, and changes in regional cerebral blood flow (rCBF) were measured as an index of neural activity. READ MORE

  4. 2. Human brains and virtual realities : Computer-generated presence in theory and practice

    Author : Daniel Sjölie; Lars-Erik Janlert; Johan Eriksson; Giuseppe Riva; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human brain function; virtual reality; presence; cognitive neuroscience; human-computer interaction; brain imaging; fMRI; BCI; neural correlates; HCI theory; reality-based interaction.;

    Abstract : A combined view of the human brain and computer-generated virtual realities is motivated by recent developments in cognitive neuroscience and human-computer interaction (HCI). The emergence of new theories of human brain function, together with an increasing use of realistic human-computer interaction, give reason to believe that a better understanding of the relationship between human brains and virtual realities is both possible and valuable.

  5. 3. Mass Spectrometry-based Neuroproteomics : Deciphering the Human Brain Proteome

    Author : Sravani Musunuri; Jonas Bergquist; Ganna Shevchenko; Jean-Charles Sanchez; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brain; Proteomics; Mass spectrometry; Alzheimer s disease; Traumatic brain injury; Membrane proteins; Sample preparation; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Abstract : Mammalian brain is challenging to study due to its heterogeneity and complexity. However, recent advances in molecular imaging, genomics and proteomics have contributed significantly to achieve insights into molecular basis of brain function and pathogenesis of neurological disorders.

  6. 4. Imaging fear and anxiety in the human brain : Positron emission tomographic studies

    Author : Håkan Fischer; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; fear; anxiety; panic; conditioning; human; brain; neuroimaging; positron emissiontomography; PET; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : Fear and anxiety are central human experiences. However, the relation between aspects of these aversive emotional states and brain function have previously been studied mostly in animals. READ MORE

  7. 5. Analysis of Human Brain MRI : Contributions to Regional Volume Studies

    Author : Richard Nordenskjöld; Joel Kullberg; Elna-Marie Larsson; Lars Johansson; Håkan Ahlström; Göran Starck; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; Brain; Volume; Hemisphere; Intracranial volume; Image analysis; Computerized Image Analysis; Datoriserad bildanalys;

    Abstract : Many disorders are associated with regional brain volumes. The analysis of these volumes from MR images often requires sequential processing steps such as localization and delineation. READ MORE
