How to build a brain – An introduction to neurophysiology for engineers

Brainless Embryos Suggest Bioelectricity Guides Growth

In recent years, by working on tadpoles and other simple creatures, Levin’s laboratory has amassed evidence that the embryo is molded by bioelectrical signals, particularly ones that emanate from the young brain long before it is even a functional organ. Those results, if replicated in other organisms, may change our understanding of the roles of electrical phenomena and the nervous system in development, and perhaps more widely in biology.

How Cheese, Wheat and Alcohol Shaped Human Evolution

As our evolution continues, the crucial role of diet hasn’t gone away. Genetic studies show that humans are still evolving, with evidence of natural selection pressures on genes impacting everything from Alzheimer’s disease to skin color to menstruation age. And what we eat today will influence the direction we will take tomorrow.
