  4. 2. Dopamine and the affective-cognitive gradient in the human striatum studied with multimodal brain imaging

    Author : Filip Grill; Anna Rieckmann; Lars Nyberg; Alison Adcock; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dopamine; striatum; incentive; motor; associative; reinforcement learning; reward prediction error; positron emission tomography; functional magnetic resonance imaging; PET MR; cognitive modelling;

    Abstract : Both dopamine and the dopamine rich brain area, striatum, have been linked to behaviors related to incentives, motor action, and associative processing. Most of the cortex sends projections to the striatum, these connections have been described as a gradient organization representing a repertoire of functional behaviors. READ MORE

  5. 3. Imaging and Quantification of Brain Serotonergic Activity using PET

    Author : Pinelopi Lundquist; Margareta Hammarlund-Udenaes; Per Hartvig; Gunnar Blomquist; Paul Cumming; Uppsala universitet; []
    Keywords : Pharmacokinetics Pharmacotherapy; Brain serotonin; Neurotransmitter release; Neurotransmitter synthesis; Positron emission tomography; Tracer validation; Tracer modelling; Farmakokinetik Farmakoterapi;

    Abstract : This thesis investigates the potential of using positron emission tomography (PET) to study the biosynthesis and release of serotonin (5HT) at the brain serotonergic neuron. As PET requires probe compounds with specific attributes to enable imaging and quantification of biological processes, emphasis was placed on the evaluation of these attributes. READ MORE

    Abstract : Stress has emerged as one of the most important factors to consider in psychiatric diagnoses and has become a common reason for long-term sick leave (LTSL). Roughly 50% of LTSL due to psychiatric diseases are thought to be associated with work-related stress. READ MORE

  7. 5. Methods for the analysis and characterization of brain morphology from MRI images

    Abstract : Brain magnetic resonance imaging (MRI) is an imaging modality that produces detailed images of the brain without using any ionizing radiation. From a structural MRI scan, it is possible to extract morphological properties of different brain regions, such as their volume and shape. READ MORE
