  1. 1. Variations in Functional Lateralization

    Detta är en avhandling från Department of Psychology, Lund University

    Författare :Peter E Wendt; Lunds universitet.; Lund University.; [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

  2. 2. Lateralization of human olfaction cognitive functions and electrophysiology

    Detta är en avhandling från Umeå : Psykologi

    Författare :Daniel Broman; Umeå universitet.; [2006]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Human olfaction; Laterality; Olfactory processes; Odor familiarity; Odor identification; OERP; SOCIAL SCIENCES Social sciences Psychology; SAMHÄLLSVETENSKAP Socialvetenskap Psykologi;

    Sammanfattning : In this thesis lateralization of olfactory functions was investigated by both behavioral and electrophysiological assessment, the latter with the olfactory event-related potential (OERP) technique. The olfactory sense is primarily ipsilateral in that a stimulus that is presented to one nostril is initially processed in the same hemisphere. LÄS MER

  3. 3. 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.

  4. 4. Mind your Language, All Right? Performance-dependent neural patterns of language

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Helene van Ettinger-Veenstra; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Language ability; performance; fMRI; functional magnetic resonance imaging; Broca; Wernicke; temporal lobe; inferior frontal gyrus; reading; fluency; lateralization; lateralisation; right hemisphere; performance-dependent; neural activation;

    Sammanfattning : The main aim of this dissertation was to investigate the difference in neural language patternsrelated to language ability in healthy adults. The focus lies on unraveling the contributions of theright‐hemispheric homologues to Broca’s area in the inferior frontal gyrus (IFG) and Wernicke’s areain the posterior temporal and inferior parietal lobes.
