Figure 7.

a–c, Immunogold labeling of CALM in tubulovesicular organelles at or near dendrite branch points in the CA1 stratum radiatum (a, b) and CA1 stratum oriens (c) of the adult hippocampus. Thin arrows indicate dendrite branch orientations. Arrowheads in a1, b1, c1 indicate the area that is enlarged in the respective micrograph a2, b2, c2. Note that the CALM-labeled tubulovesicular organelles are located at the base of branch points separating the typical microtubule-rich dendrites. Scale bars: (in c1) for a1–c1, 500 nm; (in c2) for a2–c2, 100 nm.
