P.93 right column bottom paragraph: "Transient dendritic filopodia on immature dendrites (9–11 DIV [days in vitro]) had a mean lifetime of 9.5 ± 7.7 min (mean and standard deviation, 63 filopodia, five experiments, same neurons as in Figure 4B). For this analysis, [investigators] necessarily considered only filopodia that both appeared and disappeared during the time-lapse session, while filopodia that were discernible either at the beginning or at the end of the time-lapse session (about 33%) were excluded. This selection procedure may discriminate against the more persistent filopodia, and [investigators’] mean lifetime values may therefore underestimate those that would be obtained with longer sampling periods." |
