Comparative, developmental, neurobehavioral, sexual dimorphisms

1996 “It is now recognized that other genes on other chromosomes can induce sex reversal regardless of the individual’s SRY status.
2012 “…we now know that the SRY can begin directing sexual differentiation prior to onset of hormonal secretions

Epigenetic effects on chromatin and regulatation of gene expression (in Archaea?)

the bottom-up epigenetic effects of nutrient chemicals on speciation that are concurrently controlled by the top-down epigenetic effects of pheromones on reproduction challenges those who might rather attempt to-explain away the conserved molecular biology of adaptive evolution via random mutations theory

The logic of gene regulatory networks

As an alternative, we could continue to approach disorders of behavioral developmentas if nothing were known about epigenetic links between nature and nuture.

Waiting “forever” for something to happen for the “first” time

Stochastic gene expression is not random; it results from nutrient chemicals like glucose entering the cell.

Society for Social Neuroscience Presentation scheduled 10/11/12

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
