OBJECTIVE Structural brain changes appear years before the onset of Alzheimer's disease, the leading cause of dementia late in life. Determining risk factors for such presymptomatic brain changes may assist in identifying candidates for future prevention treatment trials. In addition to the e4 allele of the apolipoprotein E gene (APOE-4), the major known(More)
People with the apolipoprotein-Eepsilon4 (APOE-4) genetic risk for Alzheimer's disease show morphologic differences in medial temporal lobe regions when compared to non-carriers of the allele. Using a high-resolution MRI and cortical unfolding approach, our aim was to determine the rate of cortical thinning among medial temporal lobe subregions over the(More)
Gene expression data are most useful if they can be associated with specific cell types. This is particularly so in an organ such as the brain, where many different cell types lie in close proximity to each other. We used zebra finches (Taeniopygia guttata), fluorescent tracers and laser capture microdissection (LCM) to collect projection neurons and their(More)
Across species structural and functional hemispheric asymmetry is a fundamental feature of the brain. Environmental and genetic factors determine this asymmetry during brain development and modulate its interaction with brain disorders. The e4 allele of the apolipoprotein E gene (APOE-4) is a risk factor for Alzheimer's disease, associated with regionally(More)
The ability to critically evaluate neuroscientific findings is a skill that is rapidly becoming important in non-science professions. As neuroscience research is increasingly being used in law, business, education, and politics, it becomes imperative to educate future leaders in all areas of society about the brain.
