1. 1. Decoding the complex brain : multivariate and multimodal analyses of neuroimaging data

   Författare :Alireza Salami; Lars Nyberg; Cheryl Grady; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multivariate analysis; univariate analysis; multimodal imaging; episodic memory; aging; functional magnetic resonance imaging; diffusion tensor imaging; biology; biologi; Psychology; psykologi; datoriserad bildanalys; Computerized Image Analysis;

   Sammanfattning : Functional brain images are extraordinarily rich data sets that reveal distributed brain networks engaged in a wide variety of cognitive operations. It is a substantial challenge both to create models of cognition that mimic behavior and underlying cognitive processes and to choose a suitable analytic method to identify underlying brain networks.

3. 2. Brain Structure and Function in Adolescents with Atypical Anorexia Nervosa

   Författare :Gaia Olivo; Helgi B. Schiöth; Christian Benedict; Jessica Mwinyi; Andreas Jansen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; functional MRI; fMRI; magnetic resonance imaging; neuroimaging; brain imaging; anorexia nervosa; eating disorders; neuroscience; adolescents; Medicinsk vetenskap; Medical Science; Neuroscience; Neurovetenskap;

   Sammanfattning : Atypical anorexia nervosa (AAN) has a high incidence in adolescents, resulting in significant morbidity and mortality. The weight loss is generally less pronounced than that experienced in full-syndrome anorexia nervosa (AN), but the medical consequences can be as severe. LÄS MER

4. 3. Non-invasive EEG Functional Neuroimaging for Localizing Epileptic Brain Activity

   Författare :Yazdan Shirvany; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Somatosensory Evoked Potentials; Forward Problem; Inverse Problem; Mathematical Dipole; Epileptic Spike; Functional Neuroimaging; Structural Magnetic Resonance Imaging; Particle Swarm Optimization; Source localization; Finite Element Method; Non-invasive EEG;

   Sammanfattning : Epilepsy is one of the most common neurologic diseases in the world, and is present in up to 1% of the world’s population. Many patients with epilepsy never receive the treatment which make them seizure free. Surgical therapy has become an important therapeutic alternative for patients with drug resistant epilepsy.

5. 4. Methodological developments in small animal PET neuroimaging

   Författare :Miklós Tóth; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Positron emission tomography (PET) is a nuclear imaging technique using a multidisciplinary approach to functionally visualize processes in the brain or other living tissue. It is capable to determine the pharmacokinetic and pharmacodynamic properties of a molecule in the CNS, with a low risk of side effects on the subject. LÄS MER

7. 5. Multimodal neuroimaging of pain and inflammation in the central nervous system in patients with fibromyalgia and rheumatoid arthritis

   Författare :Angelica Sandström; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The prevalence of concomitant fibromyalgia (FM) is puzzlingly high among rheumatoid arthritis (RA) patients and a contemporary challenge is to resolve why some RA patients continue to report pain despite adequate treatment of their peripheral inflammation. While recent literature has concentrated on the link between cerebral and inflammatory mechanisms in RA patients with concomitant FM, little attention has been directed towards commonalities and divergences among these two patient groups when they are wellcharacterized.
