learning and memory in unicellular yeasts is exemplified via epigenetically-effected changes in
gonadotropin releasing hormone (GnRH) secretion in young mammals
This model of systems biology represents the conservation of bottom-up organization and top-down activation and the required reciprocity that links genes to behavior and back.
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
