| − | '''Background Info:''' Dendritic spines are the primary sites of excitatory neuronal communication in the brain. It is of fundamental interest to cellular neurobiologists to understand how the number, size, and shape of dendritic spines varies across brain regions, and as a function of experimental treatment within a given region.
