       PRESENTATION HIGHLIGHTS:

  • [00:00:00] Is the blinking of the quantum dots a problem?
  • [00:01:33] You mentioned that these actin rings are at different neurons. Are there similar structures on non-neuronal cells or is it specific to neurons?
  • [00:03:23] Was your tracking 2D or 3D?
  • [00:04:49] Are there actin rings at the plasma membrane possibly seen in other eukaryotic cells?
  • [00:08:25] How did you determine the ideal localization density for the pope?
