New animal research finds life experiences influence brain development, behavior
Washington — Scientists presented new research today demonstrating the impact life experiences can have on genes and behavior. The studies examine how such environmental information can be transmitted from one generation to the next — a phenomenon known as epigenetics. This new knowledge could ultimately improve understanding of brain plasticity, the cognitive benefits of motherhood, and how a parent‘s exposure to drugs, alcohol, and stress can alter brain development and behavior in their offspring.

Some of us are hopeful that epigenetics will get past the useless bad genes vs. “bad environment” conflict, to find out what is really happening when people have predictable bad health problems.
