L5 neuron activation by multi-mode photostimulation. a The ensemble response probability of neurons to the simultaneous photostimulation of targets A and B (A + B, dark blue columns) as a function of the distance along a direction parallel to the cortical surface, where the background columns are the ensemble response probability to the single-mode photostimulation at A (light blue) and at B (light green). b Similar to A, but of targets B and C (B + C, dark green columns). c Similar to A, but of targets A and C (A + C, brown columns). d Comparison of the average response probability of the region ± 75 µm from the center of targets A and B (double-headed arrows shown in A). The symbols with lines indicate the individual data whereas each column with bars is mean ± SEM (A: n = 5, B: n = 5, A + B: n = 10). e Similar to D, but of targets B and C. f Similar to D, but of targets A and C. *P < 0.05, ***P < 0.0005, paired t-test (color figure online)
