The NMDA receptor antagonist CPP preferentially reduces peak activation of photostimulation-evoked VSD responses in a laminar-specific manner. (A1 and A2) are the averaged images across the initiation phase of VSD responses to photostimulation in layer 2/3 in normal ACSF and CPP, respectively. (A3) is the difference image between (A1 and A2). In these images, only the pixels with amplitudes ≥1 SD are plotted. (B1 and B2) are the averaged images across the peak phase of VSD responses to photostimulation in layer 2/3 in normal ACSF and CPP, respectively. (B3) is the difference image between (B1 and B2). (C1 and C2) Are the averaged images across the initiation phase of VSD responses to photostimulation in layer 4 in normal ACSF and CPP, respectively. (C3) Is the difference image between (C1 and C2). (D1 and D2) are the averaged images across the peak phase of VSD responses to photostimulation in layer 4 in normal ACSF and CPP, respectively. (D3) is the difference image between (D1 and D2). (E and F) Show laminar distributions of image pixels in (B3 and D3) at the peak phase, respectively. The x axis indicates the vertical location of image pixels from layer 2/3 to layer 6 (from the top to bottom of the image); the y axis denotes the number of row-wise summed pixels of the image.
