Method Abstract:"Axo-dendritic synaptogenesis was examined in live hippocampal cell cultures using the fluorescent dyes DiO to label dendrites and FM 4-64 to label functional presynaptic boutons."
Comments P.93 left column 2nd paragraph:"Filopodial protrusive activity defines a zone extending 5–10 μm from the dendritic shaft that is periodically occupied by the filopodia of that dendrite. This is exemplified in Figure 3C. This figure was created by plotting, for each filopodium, a line proportional to the peak length it had attained during the time-lapse sequence in Figure 3A and suggests that dendritic filopodia are capable of exploring a considerable volume on all sides of a dendritic shaft."
