Figure 2—figure supplement 1. Examples of branch-specific persistent calcium activity. ; (A) Example of branch-specific persistence of calcium activity following multi-branch events in the dendrites of a L2/3 neuron (soma not imaged in this session). Top, example apical trunk (black) and two dendritic branches (light and dark magenta) calcium signals. Bottom, maximum intensity projections (au) and branch insets at example times (dashed vertical lines in upper traces). Note persistent activity in one dendritic branch (light magenta) that is not present in the other (dark magenta). (B) Same as (A), but for the apical tuft of a L5 neuron. (C) Another example of (B). (D) Example of a putative independent branch event in the apical tuft of a L5 neuron. Note the large increase in calcium signal in one branch (light magenta), but no detectable increase in the apical trunk or other branch.
