1. 1. Reliability of visual assessment of medial temporal lobe atrophy

   Författare :Lena Cavallin; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Medial temporal lobe atrophy (MTA) has been found to be an early sign of Alzheimer’s disease (AD). Visual assessment of MTA (vaMTA) is a rapid, cost-efficient and clinically adaptable visual interpretation method for rating MTA, based on coronal magnetic resonance imaging (MRI) scans. LÄS MER

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

   Författare :Helene van Ettinger-Veenstra; Maria Engström; Peter Lundberg; Thomas Karlsson; Anita McAllister; Karsten Specht; Linköpings universitet; []
   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.

4. 3. The limbic-hypothalamic-pituitary-adrenal axis in Alzheimer's disease

   Författare :Birgitta Näsman; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; multi-infarct dementia; hippocampus; temporal lobe; adrenal androgens; adrenocorticotropin; corticotropinreleasing hormone; cortisol; skin blanching;

   Sammanfattning : Dysfunction of the limbic-hypothalamic-pituitary-adrenal (LHPA) axis is a common finding in advanced dementia. In this study, the function of the LHPA axis at different levels was investigated in patients with dementia and in healthy elderly.A subtle disturbance in the feedback regulation of the LHPA axis was found in patients with early (i.e. LÄS MER

5. 4. Source localisation of epileptiform activity in epilepsy of temporal lobe origin

   Författare :Göran Lantz; Klinisk neurofysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; frequency analysis; ictal; singe photon emission computed tomography; volume conduction; extracranial; intracranial; LORETA; dipole; source localisation; epilepsy; mesolimbic; Fast Fourier Transform; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

   Sammanfattning : In patients with drug resistant partial epilepsy, who are under consideration for epilepsy surgery, interictal and ictal EEG recorded with extracranial electrodes plays an important role in the localisation of the seizure onset area. During the past years, methods have been developed, which can be used to estimate the location of the source of epileptiform activity in the brain from extracranial EEG data. LÄS MER

7. 5. Effects of Meditation on Respiration and the Temporal Lobes : An Exploratory and Meta-Analytic Study

   Författare :Yvonne Petersson Bouin; Centrum för teologi och religionsvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; Personality; Cognition; Emotions; Deconditioning; Amygdala; Temporal lobes; Carbon dioxide; Meditation; Respiration; Meta-analysis; Theology; Teologi;

   Sammanfattning : Two assertions made by the Eastern meditation traditions were investigated: (a) breath regulation is a prerequisite for attaining altered states of consciousness, (b) meditation leads to changes in cognitive processes and in personality. A deconditioning process was conceptualized involving the temporal lobes and the amygdala. LÄS MER
