Cerebral blood flow associated with creative performance: a comparative study.

Creativity is important for social survival and individual wellbeing; science, art, philosophy and technology have been enriched and expanded by this trait. To our knowledge this is the first study probing differences in brain cerebral blood flow (CBF) between highly creative individuals (scientists and/or artists socially recognized for their contributions to their fields with creativity indexes corresponding to the 99% percentile) and average control subjects while performing a verbal task from the Torrance Tests of Creative Thinking. Additionally, we correlated CBF with creativity dimensions such as fluency, originality and flexibility.

Distribution of apolipoprotein E alleles in coras and huicholes from Nayarit and Nahuas and Mestizos from Veracruz, Mexico.

We report allele frequencies for the most common polymorphism of the APOE gene in Mexican individuals from two regions not previously described: Coras and Huicholes from Nayarit, and Nahuas and mestizos from Veracruz. We also report APOE allele frequencies for inhabitants of Mexico City. These descriptive data underscore the allelic heterogeneity for this particular locus in Mexico.
