Fig. 3.

VSD imaging of V1 responses to the apparent motion stimuli following the real motion. (A and B, Upper) stimulus sequence as in Fig. 2. (Lower) Example of VSD signals in response to the apparent motion stimuli immediately after the real motion along path A and path B, respectively. (Scale bar, 500 μm.) (C) Difference of VSD responses (“Δ response”) to the apparent motion stimuli for the example recording shown in A and B. Red and blue arrowheads mark the cortical regions representing path A and path B, respectively. Black contour lines are the same as in Fig. 2C, representing cortical regions with strong positive Δ response to the real motion stimulation. (D) Average Δ response to apparent motion stimuli from all of the experiments (n = 19 mice).
