a, Examples of sCRACM maps overlaid on reconstructed dendritic arbors and fluorescence images. b, Group averages aligned by pia position. White triangles, soma position. c, sCRACM map of POm input onto a L5A pyramidal cell (blue). No responses were detected on the L5B neuron (green). d, EPSCsCRACM recorded on the L5A neuron (blue) or the L5B neuron (green) when photostimuating the boxed regions in Panel c . The stimulus occurred at the beginning of each trace.
