Fig. 10.

The auditory stream is depicted. We begin with the superposition of objects 4 and 3, and their corresponding visual maps. We normalize the grayscale image of the superposed objects before display. The phase of the first winner (in blue) corresponding to object 4 in the upper layer y is 0.588 radians. The phase of the second winner in y (in red) corresponding to object 3 is 3.767. We use a vector field to display the activity in the lower layers. The magnitude of a vector reflects the amount of activity in a unit, and its direction encodes the phase of the unit.
