1. Aerobic fitness and healthy brain aging : cognition, brain structure, and dopamine
Abstract : Background: Performing aerobic exercise and maintaining high levels of aerobic fitness may have positive effects on both brain structure and function in older adults. Despite decades of research however, there is still a rather poor understanding of the neurocognitive mechanisms explaining the positive effects of aerobic exercise on cognition. READ MORE

2. Quantitative MRI Biomarkers of Neurodegeneration in Multiple Sclerosis
Abstract : Background: Multiple sclerosis (MS) is a chronic neuroinflammatory and neurodegenerative disease that targets myelin in the brain and spinal cord. The corpus callosum connects the cerebral hemispheres and is composed of heavily myelinated axons. READ MORE

3. Analysis of Human Brain MRI : Contributions to Regional Volume Studies
Abstract : Many disorders are associated with regional brain volumes. The analysis of these volumes from MR images often requires sequential processing steps such as localization and delineation. READ MORE

4. Regimented language training : Changes to brain and behaviour following intensive non-native language learning
Abstract : The influence of foreign-language acquisition on adult brain structure remains mostly unexplored. Whilst several cross-sectional studies have led to further understanding of how language can affect brain structure, only a few longitudinal studies have been conducted. READ MORE

5. Methodological advancements in data analysis and quantitative performance of positron emission tomography
Abstract : Positron emission tomography (PET) is a medical imaging modality with which neurophysiological functions can be studied. After a radio-labeled molecule is injected intravenously, it is transported by the blood stream to the target of interest. The radioactive atom of the molecule decays, resulting in two gamma rays that the PET system detects. READ MORE
