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

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

    Abstract : 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. READ MORE

  2. 2. Episodic memory in the human prefrontal cortex

    University dissertation from Stockholm : Karolinska Institutet, Department of Clinical Neuroscience

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

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

    University dissertation from Umeå : Umeå university

    Author : Kristiina Kompus; Lars Nyberg; Katrine Åhlström Riklund; Emrah Düzel; [2010]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

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

    Abstract : 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. READ MORE

  5. 5. Neuropsychological Function in Relation to Structural and Functional Brain Changes in Alzheimer’s Disease

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Eva Elgh; Jarl Risberg; [2004]
    Keywords : Alzheimer´s disease; neuropsychological function; episodic memory; hippocampus; prefrontal cortex; brain imaging; MRI; fMRI; SPECT; LHPA-axis; cortisol; geriatrik; Geriatrics;

    Abstract : The aim of this doctoral thesis was to study neuropsychological function in relation to structural and functional brain changes in Alzheimer´s disease (AD).In the first study relations between hippocampal volume, neuropsychological function and limbic-hypothalamic-pituitary-adrenal (LHPA) axis disturbances in AD were investigated with magnetic resonance imaging (MRI).
