Information content of perievent spiking. Mutual information between 5-ms-binned spike counts and target direction (the Cartesian direction from the location of the previous target to the location of the new target) (see Materials and Methods). The solid line is the mean information obtained from the spiking of the 10% of units that were most the precisely firing. The dashed line is mean over the 25% of units that were most precise. The gray line is mean over all units.
