P.96 right column 3rd paragraph: "As previously noted, dendritic protrusions associated with a presynaptic bouton were, as a rule, persistent. This does not necessarily reflect a global condition of either the dendrite or the target cell as a whole. In neurons younger than 16 DIV [days in vitro], some (but not all) neighboring dendritic protrusions not associated with presynaptic boutons displayed relatively high motility levels (see, for example Figure 7A). A quantitative comparison of the average motility levels of protrusions associated with presynaptic boutons (average motility = 0.59 μm/3 min) to those not associated with presynaptic boutons (average motility = 1.30 μm/3 min) supports this observation (6 neurons, 160 filopodia and spines, 11–15 DIV)." |
