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. Telomeres and the brain : an investigation into the relationships of leukocyte telomere length with functional and structural attributes of the brain
Abstract : Telomeres are the outermost parts of linear chromosomes. They consist of tandemly repeated non-coding short nucleotide sequences (TTAGGG in all vertebrates), in humans spanning over the last 2 to 15 kilobase pairs of the chromosome. Due to the end-replication problem, telomeres shorten with each cellular division. 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

5. Regulation of site-selective A-to-I RNA editing : During mammalian brain development
Abstract : Adenosine (A) to inosine (I) RNA editing is a widespread post-transcriptional mechanism in mammals that contributes to increase the protein diversity. Adenosine deaminases that act on RNA (ADARs) are the enzymes catalyzing RNA editing. ADARs are particularly active within the brain where they act on transcripts involved in neurotransmission.
