Plasma membrane dynamics in dendrites of a live hippocampal neuron at 37 °C. (A) Morphological changes of dendritic structures captured by a series of 10-sec STORM snapshots. Green arrowhead: A growing spine or filopodium. Blue arrowhead: An extending filopodium. Purple arrowhead: A retracting filopodium. (B–E) High-density single-particle-tracking of DiI. (B) Molecular trajectories lasting at least 15 camera frames (2 ms per frame) colored by their diffusion coefficients, D, according to the color map on the Right. (C) Diffusion coefficients in different dendritic structures. Error bars indicate standard errors: N = 613 traces for shaft; N = 90 traces for spine/filopodia. (D) A zoom-in of the boxed region in B. (E) Local distribution of diffusion coefficients within the filopodium in the dashed box in D. Error bars indicate standard errors (N = 7–18). Scale bars, 1 μm.
