Dendrites are of strategic importance in understanding the cellular organization of the neural circuits in the brain because they form the receptive surface for the many thousands of synapses that converge on a single neuron. I examine dendrites as a way of understanding how neurons are built during early development and become “plastic” to store new information from individual experience. Working with long-term collaborator Ginger Withers, I combine behavioral, anatomical and molecular techniques to identify structural changes in dendrites and accompanying changes in gene expression to understand their molecular regulation. Currently, we are at work on 3 related areas of research in developmental neurobiology: 1) development of mRNA transport and localization in dendrites, 2) the “social” regulation of the onset of dendritic plasticity through the interactions between neurons, glial cells and blood vessels, 3) using diminished plasticity as a novel assay for subtle brain damage caused by exposure of the developing brain to harmful chemicals.
