English: The ΔV(t) of the occlusion condition and the estimate of the position of the cortical position of the representations of the bar without delay in one animal. (A) Animation of the stimuli in the occlusion condition with a frame frequency of 200 Hz. Distance from the center of field of view shown on the sides of the monitor. Time in ms from the start of motion is shown in green. (B) The voltage sensitive dye signal, ΔV(t), in the occlusion condition. The scale to the right shows the absolute values. Yellow and colors above yellow signify significant changes (p < 0.01). Notice the two spatially restricted depolarizations starting along the 19/21 border (115 ms), and then shortly after along the 17/18 border. For location of cytoarchitectural borders in this animal see C and D. Notice also the almost simultaneous decrease in the ΔV(t) starting at 445 ms. (C) Location of the bar representation without delay in response to single bars, here shown as downward moving, after (Kalatsky and Stryker, 2003) (see details in Figure A1). (D) Bonferoni corrected (p < 0.01) and normalized, ΔV(t)rel(s), signal for a downward moving bar. This movie shows only the significant responding after the presentation of a bar moving downward along the vertical meridian.
