Pharmacogenomics

genetic code RNA medium

“The gene, cell, tissue, organ, organ-system pathway is a neuroscientifically established link between sensory input and behavior. Marts and Resnick (2007) stress the importance of this pathway in the context of a systems biology approach to pharmacogenomics.” (Kohl, 2012) “Naftolin…

Ecological variation and niche construction: 1, 2, 3

human-brain

Part 1 From its most basic expression in grazing and predatory nematodes with differences in morphological and behavioral phenotypes, neurogenic niche construction is nutrient-dependent and pheromone-controlled. One of these two worms has teeth. It also recognizes self vs other differences…
