  1. 1. The prefrontal cortex and information processing : nitric oxide signaling studied in an animal model of schizophrenia

    Författare :Kim Fejgin; Göteborgs universitet.; Gothenburg University.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; schizophrenia; nitric oxide; prepulse inhibition; phencyclidine; prefrontal cortex; cGMP; baclofen; cognition;

    Sammanfattning : The prefrontal cortex has been extensively linked to several cognitive domains that are severely compromised in schizophrenia. It has therefore become a key region for studies on the disabling cognitive dysfunction commonly observed in patients with schizophrenia. LÄS MER

  2. 2. Episodic memory in the human prefrontal cortex

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

    Författare :Johan Sandblom; Karolinska Institutet.; Karolinska Institutet.; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : This thesis consisting of five papers examines the relationship between haemodynamicactivation in the prefrontal cortex with episodicmemoryfunction in the healthy human brain. Brain function is measured with positron emission tomography (PET) and functional magnetic resonance imaging (FMRI) and episodic memory for words as well as visuo-spatial material is examined.

  3. 3. Variations in Functional Lateralization

    Detta är en avhandling från Department of Psychology, Lund University

    Författare :Peter E Wendt; [1998]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; posterior association cortex; prefrontal; DLPFC; regional cerebral blood flow; normal subjects; lateralization; asymmetry; performance; creativity.; Neurology; neuropsychology; neurophysiology; Neurologi; neurofysiologi; neuropsykologi; cognitive; ethanol; activation; visual stimulation; functional; verbal; divergent; spatial;

    Sammanfattning : The general aim of this thesis was to study asymmetric activation of the neocortex in normal subjects, using the rCBF technique and different cognitive tasks. The aim was also to study individual and group variations of asymmetric activation, as well as factors pertaining to these variations. The thesis is based on four investigations. LÄS MER

  4. 4. How the past becomes present neural mechanisms governing retrieval from episodic memory

    Detta är en avhandling från Umeå : Umeå university

    Författare :Kristiina Kompus; Lars Nyberg; Katrine Åhlström Riklund; Emrah Düzel; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; episodic retrieval; cognitive control; retrieval intention; prefrontal cortex; functional magnetic resonance imaging; event-related potentials; MEDICINE Physiology and pharmacology Physiology Neurophysiology; MEDICIN Fysiologi och farmakologi Fysiologi Neurofysiologi; diagnostisk radiologi; Diagnostic Radiology;

    Sammanfattning : Remembering previously experienced events can happen as a result of an effortful retrieval attempt. At other occasions, a memory can enter our minds without any apparent effort – or, indeed, intention - to retrieve. LÄS MER

  5. 5. Mind really does matter The Neurobiology of Placebo-induced Anxiety Relief in Social Anxiety Disorder

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Vanda Faria; Tomas Furmark; Mats Fredrikson; Predrag Petrovic; [2012]
    Nyckelord :HUMANIORA; HUMANITIES; Placebo effect; anxiolysis; SAD; PET; TPH2 G-703T polymorphism; SSRIs; amygdala subregions; prefrontal cortex.; Psychology; Psykologi;

    Sammanfattning : The placebo effect, a beneficial effect attributable to a treatment containing no specific properties for the condition being treated, has been demonstrated in a variety of medical conditions. This thesis includes four studies aimed at increasing our knowledge on the neurobiology of placebo. LÄS MER
