learning and memory in unicellular yeasts is exemplified via epigenetically-effected changes in
gonadotropin releasing hormone (GnRH) secretion in young mammals
We incorporated what is currently known about the ability of chemical signals to condition behavior. This conditioning occurs via epigenetic effects that calibrate and standardize the molecular biology of intracellular signal transduction and stochastic gene expression
Epigenetic influences of nutrition and socialization on intracellular signalling pathways link epigenetic cause directly to gene activation and stochastic gene expression are required for genetically predisposed phenotypic changes in the body and behavior of organisms from microbes to man.
