Fig 5.

Electrode tracks, one from each of the four animals, with locations of the functionally identified cells, reconstructed from three or four Nissl-stained sections. The koniocellular extensions into the parvocellular layers (into P3 in A, B and D and P4 in C) near the electrode tracks are shown, but not all such koniocellular bridges in the sections are shown in the figure. The inset provides the key for cell types. The horizontal black lines on the electrode tracks indicate the sites of electrolytic lesions.
