Area PEc Neurons Use a Multiphasic Pattern of Activity to Signal the Spatial Properties of Optic Flow

Figure 3

Pattern of activity of a PEc exemplary neuron: multiphasic and burst/pauses activity. On the top spike density plots (50 ms bin). On the bottom raster plot of firing rates, each vertical bar represents a single action potential. Spikes are aligned with the lever press. (a)–(y) Neural activity during expanding (EXP) and contracting (CONTR) radial optic flow stimuli, with nine different foci of expansion (FOE) and/or fixation. The (x)/(y) position of the FOE/FP is reported at the left of the raster plot. Data set: unit F232, the same cell as in Figure 2. Conventions as in Figure 1.
